Pharmacokinetics and Indications:Trenbolone Enanthate is a 19-nortestosterone (19-nor) anabolic androgenic steroid. The 19-nor label refers to a structural change of the testosterone hormone in that it lacks a carbon atom at the 19th position. This is the same classification given to the popular Nandrolone hormone that makes up the popular anabolic steroid Deca Durabolin. In fact, Trenbolone is simply a modified form of Nandrolone, which itself is simply a structurally altered form of testosterone. When we break down various steroids, it is very slight changes that give us massive differences, but the relationships in a total sense are often far more closely related than we might realize. As for the Trenbolone hormone, it is the Nandrolone hormone with an added double bond at carbons 9 and 11. This structural change slows its metabolism, greatly increases its binding affinity to the androgen receptor and inhibits it from aromatizing. While this is truly a slight modification, it truly creates a different hormone and one that is far more powerful than Nandrolone. Trenbolone Enanthate, like all Tren carries and anabolic rating of 500 and an androgenic rating of 500. More importantly, its translating activity matches its structural ratings perfectly, meaning strong and pronounced anabolic and androgenic effects will be displayed.
Beyond the structural nature of Trenbolone, Trenbolone Enanthate carries the Enanthate (enanthoic acid) ester. The ester does not affect the Trenbolone hormone. This version will not create a more or less powerful Tren compound or change any of the traits of the hormone. It will, however, affect the hormone’s release time post injection, which will be much slower than the Acetate version. It will carry a longer half-life similar to Testosterone Enanthate. The Enanthate ester attached will also affect the compounds concentrated potency. On a milligram for milligram basis, Trenbolone Acetate is stronger than Trenbolone Enanthate due to the Enanthate ester taking up more mass in the compound. With the Acetate version, the Acetate ester is small, therefore takes up less mass in the total compound. However, total dosing can be adjusted with either form, which will enable you to receive the same amount of active Trenbolone with any form you choose. The following chart will breakdown the potency and milligram for milligram discrepancies:
87mg per 100mg
72mg per 100mg
50mg per 76.5mg
Parabolan is always found in 76,5mg/ml form, whereas the Acetate version is normally found at 50-100mg/ml and the Enanthate version 100-200mg/ml.
Trenbolone Enanthate carries with it several primary anabolic steroidal traits that make it one of the most versatile and powerful anabolic steroids of all time. Many of the traits are very similar to numerous anabolic steroids. However, the Trenbolone hormone simply carries them at a rate of power far beyond and above most others. When we consider this rate of power alongside its lacking of aromatase activity, which we will go over in the side effects section, this makes it an even more valuable hormone. All in all, Trenbolone Enanthate carries seven primary functional traits that are worthy of mention and largely define the hormone’s mode of action. The traits include the following:
 Enhanced Protein Synthesis:
Protein is the primary building block of muscle. It is not the only important factor but it is primary. Protein synthesis refers to the rate by which cells build proteins and as synthesis is increased more is available for work and production. This increases the body’s anabolic atmosphere, and also greatly improves the overall rate of recovery, which is essential to total progress. This is not only important during periods of growth, but essential to periods of weight loss in a preservation capacity. We will find all the primary functional traits of Trenbolone Enanthate to be equally important and valuable in bulking and cutting phases.
 Enhanced Nitrogen Retention:
All lean muscle tissue is comprised of approximately 16% nitrogen. As nitrogen levels fall, this can lead to a catabolic (muscle wasting) state. The more nitrogen we retain the more anabolic we remain. Again, the anabolic atmosphere is enhanced, recovery is improved and progress enjoyed.
 Increased Red Blood Cell Count:
Red blood cells are responsible for carrying oxygen to and through the blood. As red blood cell count increases, this increases blood oxygenation levels. With greater blood oxygenation, this greatly improves muscular endurance. It will also promote more efficient muscular recovery and even play a role in a direct conditioning sense of a visual nature.
 Increased IGF-1 Output:
Insulin-Like Growth Factor-1 (IGF-1) is a powerful protein hormone of the peptide class that is primarily produced by the liver. The hormone plays an integral role with Human Growth Hormone (HGH) in a regulation sense and is extremely anabolic. It is also essential to recovery and our body’s ability to rejuvenate. So important, IGF-1 actually affects nearly every cell in the human body from muscle tissue, ligaments and tendons, cartilage, bone, the central nervous system and even affects our lungs to a degree.
 Inhibition of Glucocorticoids:
Glucocorticoid hormones are essential to our health but only in minimal levels. These are muscle wasting and fat promoting hormones and while important to our immune system can bring havoc to the body when found in abundance. Hard training, and even more so when coupled with hard dieting can greatly increase in amount, cortisol being primary and the most well know. Trenbolone Enanthate will ensure levels are kept to a minimum state, in turn ensuring the powerful anabolic atmosphere is maintained.
 Strong Binding Affinity to the Androgen Receptor:
Most all anabolic androgenic steroids will promote a stronger and more powerful metabolism. However, steroids that bind firmly to the androgen receptor have been linked to the promotion of direct lipolysis (fat loss). Trenbolone Enanthate can actually help you directly burn body fat. As we will later see, this is actually very beneficial during off-season periods of growth, as well as periods of cutting.
 Increased Feed Efficiency:
The above six functional traits of Trenbolone Enanthate are enough to make this a very powerful and beneficial anabolic steroid. However, its ability to increase or enhance feed efficiency, often referred to as nutrient efficiency is what truly makes the Trenbolone hormone the greatest anabolic steroid of all time. By supplementing with Trenbolone Enanthate, each and every nutrient we consume becomes more valuable. We are now able to make better use of every last gram of fat, protein and carbohydrates we consume. Without a hormone like Tren, the body can only utilize each nutrient to a certain degree. This will vary depending on the precise food in question, but each nutrient will never be utilized fully. With Tren, the utilization is enhanced, the same total caloric intake becomes more valuable and more progress is made. This is the very reason Trenbolone is given to livestock before slaughter. In this case, it will be Trenbolone Acetate and actually in the form of subcutaneous implant pellets known as Finaplix.
Effects of Trenbolone Enanthate:
From looking at the functional traits of Trenbolone Enanthate, it’s not too hard to see how valuable this hormone can be. Further, you should already have a good idea of the effects that can be enjoyed. However, we want to look at the effects of Trenbolone Enanthate in a more realistic way. Specifically, we want to explain what you can expect due to supplementation. We cannot pinpoint every last effect to the full possible degree. This will vary from one man to the next and can be dependent on numerous factors, but the following will give you a very good idea of what can be obtained.
The Trenbolone hormone is well known for being the greatest anabolic steroid for cutting purposes, and that’s a hard point to argue against. However, compounds like Trenbolone Enanthate are also tremendously beneficial during periods of off-season growth. This anabolic steroid has the ability to promote true lean tissue growth at a rate far above and beyond most anabolic steroids. More importantly, it will do so in a cleaner way than most steroids. Many steroids associated with off-season bulking often promote large amounts of water retention, but this is impossible with Tren. Each and every pound of weight gained due to the use of this hormone will be pure lean muscle mass. Of equal importance, the individual will find he gains less body fat during his off-season phase due to this steroid’s tremendous metabolic enhancement and fat burning properties.
When considering off-season use of Trenbolone Enanthate, there is something we must keep in mind. Use will help the individual control his body fat, but this does not mean body fat is impossible to gain. You must consume a level of calories above maintenance to truly grow. Thankfully, with Tren you will make better use of each calorie and the metabolic factors will also provide fat gain protection. However, there will still be a cutoff point. The use of Tren in the off-season is not a license to eat like there’s no end in site. You can still gain plenty of body fat if you don’t exercise self-control.
Then we have the cutting phase, and we can say with confidence there is no anabolic steroid on earth more valuable to this phase than Trenbolone. Trenbolone Enanthate, as should be obvious will help you burn fat at a more powerful and far more efficient rate. That alone is a benefit but it is far from the primary one. There is no anabolic steroid that will preserve lean mass like Tren and that is one of the two key goals during a diet. In order to lose body fat, we must burn more calories than we consume. This can put our lean tissue at risk and the body will begin to feed on it in order to meet its energy demands. It will often feed on it before body fat as part of its survival instinct, especially once our body fat levels become low. If we’re losing weight, but also losing muscle tissue this is not successful dieting. The goal is to lose body fat while maintaining as much muscle tissue as we can. Trenbolone Enanthate will provide this protection and ensure we burn only body fat and not our hard earned muscle tissue. The hormone will also promote strong conditioning effects. Hardness, increased vascularity and overall greater definition are all common with Tren. In fact, you can take any two steroids on earth and combine them and not receive the conditioning effects provided at the rate of power of Tren.
All who supplement with Trenbolone Enanthate will find their muscular endurance is greatly enhanced. Bulking or cutting this will occur, as will a dramatic improvement in recovery. This all leads to greater progress and a more efficient body in a physical functioning capacity. However, some have reported issues of decreased cardiovascular endurance when using Tren, and this will keep some athletes from using it. However, it is not a guaranteed effect by any means. Many will be able to use the hormone without any negative effect on cardiovascular endurance. It appears to be very individually based. All who use Trenbolone Enanthate, especially in the off-season should also find their strength greatly increases. Even at maintenance calorie levels strength increases should be significant. During a calorie deficit, especially when the individual becomes very lean, an increase in strength should not be expected. However, the use of Tren should ensure you maintain far more strength than you would otherwise.
Possible Side effects:Trenbolone Enanthate is not what we’d call the most side effect friendly anabolic steroid of all time. There are many possible side effects of Trenbolone Enanthate use, but possible is the key word. The side effects of Trenbolone Enanthate with one exception are not guaranteed. Many of the possible side effects are very similar to many other anabolic steroids and most should find they are very easy to control. However, there are certain response side effects of Trenbolone Enanthate that will keep many from being able to use this hormone. There will be more who cannot use the Trenbolone hormone perhaps more so than any anabolic steroid. However, the majority of men should still tolerate the hormone well despite a stronger number not being able to use it compared to most steroids. In order to help you understand the possible side effects of Trenbolone Enanthate, we have broken them down into their separate categories along with all the information you’ll need.
Trenbolone Enanthate is not estrogenic in that it does not aromatize. There is no testosterone to estrogen conversion with this hormone making water retention impossible due to use. However, the hormone does carry a strong progestin nature, which can make gynecomastia a concern, especially in sensitive individuals. When combined with the use of an aromatizing steroid, this appears to increase the risk. Progesterone has the ability to stimulate the estrogenic mechanism in the mammary tissue, which in turn can promote gynecomastia. In order to combat this issue, some men will need an anti-estrogen.
When it comes to Tren produced gynecomastia, there has been a prevailing myth that has been passed around message boards for years. The myth simply states that it’s the possible prolactin buildup caused by Trenbolone that leads to gynecomastia, but this simply isn’t true. William Llewellyn has largely dispelled this myth showing the intrinsic relationship between estrogen and progesterone imbalances and their effects on the mammary tissue. In his Anabolics series, you will find he goes into great detail explaining this issue.
Trenbolone Enanthate is highly androgenic, which can lead to acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth. The androgenic side effects of Trenbolone are, however, highly dependent on genetic predispositions. If you are not predisposed to male pattern baldness, losing any hair will be impossible. If you are not normally acne sensitive, the odds of any related problem during use is unlikely.
Those who are sensitive to the androgenic side effects of Trenbolone Enanthate will often attempt to combat them with a 5-alpha reductase inhibitor. This is very common and is also a waste of time. Such inhibitors, Finasteride being primary, are commonly used to reduce the androgenicity of a steroid that is brought on by a reduction of testosterone to dihydrotestosterone (DHT). This is all caused by the hormone being metabolized by the 5-alpha reductase enzyme, but Trenbolone is not metabolized by this enzyme. As a result, the use of any related inhibitor will have very little to no affect on the hormone’s androgenicity.
The possible cardiovascular side effects of Trenbolone Enanthate are by far the most concerning. In the present moment of use many are often far more concerned with gynecomastia, but this is merely a visual issue. Cardiovascular issues can directly and negatively affect your health. The primary area of concern will surround cholesterol. Tren can increased LDL cholesterol (bad cholesterol) levels and suppress/reduce HDL cholesterol (good cholesterol) levels. This cholesterol strain should not be as strong as many oral steroids, but potentially more severe than most injectable steroids.
In order to control your cholesterol, living a healthy lifestyle is imperative. A healthy lifestyle should include a cholesterol friendly diet that is low in saturated fats and simple sugars and abundant in omega fatty acids. Supplementing daily with large amounts of fish oils is normally advised. The individual should also ensure he implements plenty of cardiovascular activity on a regular basis and this includes off-season periods of growth. Do not buy into the idea that cardio is damaging to your off-season gains. You do not have to implement contest style cardio programs during your off-season but a regular amount for your health is recommended. This will, however, actually help you with off-season growth. It will keep your metabolism even stronger, minimize off-season fat gain and lead to a better physique. If you already have high cholesterol or cannot maintain a healthy cholesterol level during use you should not use this anabolic steroid.
Trenbolone Enanthate can also have a negative impact on blood pressure. The odds are in most men’s favor, especially since water retention, a primary promoter of high blood pressure is impossible with this steroid. However, high blood pressure is possible and you should keep an eye on it. Most healthy adult men will be fine if they live a healthy lifestyle.
All anabolic steroids will suppress natural testosterone production; however, the rate of suppression varies greatly from one steroid to the next. In the case of Trenbolone Enanthate, suppression will be dramatic and will not be affected by genetics. Due to the powerful rate of suppression all men who supplement with Trenbolone are strongly encouraged to include exogenous testosterone into their plan. Those who do not include exogenous testosterone will fall into a low testosterone state. Low testosterone comes with numerous possible symptoms. Sexually related symptoms are the most common, such as erectile dysfunction and suppressed libido, but they are far from the only ones. It is actually possible to suffer from low testosterone without sexually related symptoms and while the symptoms are not directly life threatening the condition is extremely unhealthy. The form of testosterone you choose is inconsequential. All that matters is you provide your body with this essential hormone.
Once the use of all anabolic steroids comes to an end natural testosterone production will begin again on its own. However, you will be at a low testosterone level for quite sometime. This can begin to produce low testosterone symptoms, which can include a loss of muscle mass and strength. It is very easy for cortisol to become dominant during this phase. For this reason, most men are encouraged to implement a Post Cycle Therapy (PCT) plan if they are going to be off-cycle for any decent length of time.
A PCT plan will stimulate natural testosterone production and greatly reduce the total recovery time. There is, however, no PCT plan on earth that will get you back to normal on its own, this will still take time. However, such a plan will ensure you have enough testosterone for proper bodily function while your levels continue to naturally rise.
Important notes on natural testosterone recovery; natural recovery assumes no prior low testosterone condition existed. It also assumes there was no severe damage done to the Hypothalamic-Pituitary-Testicular-Axis (HPTA) due to the improper use of anabolic steroids.
Trenbolone Enanthate is not what we’d traditionally consider a hepatotoxic anabolic steroid. However, there does appear to be a level of toxicity associated with extremely high doses, but such doses are extremely high and far beyond what even most hardcore bodybuilders would attempt. The average Trenbolone user should not experience any hepatic stress or damage.
There are four possible side effects of Trenbolone Enanthate that are 100% based on individual response and the subject of numerous myths surrounding the hormone. The effects have become such a topic of debate on many message boards that some believe if you don’t experience them your Tren must be no good. Not only is this ridiculous but it’s a borderline insane way of thinking. Successful use of any anabolic steroid not only refers to progress made but progress made without side effects or issues of concern. However, it will be the response based side effects of Trenbolone Enanthate that will keep some men from being able to use this hormone. In some cases, lowering the dose can fix the problem, but many who suffer will find that such effects occur even at low doses. The response effects include anxiety, insomnia, night sweats and rapid heart rate. They can also be so strong that they become unbearable. If a low dose of Tren causes such effects in you the hormone is probably not for you. If such effects occur, the best course of action is to discontinue use and try again later on at a lower dose. If problems still occur, this hormone is in no way for you. That may seem unfair but it’s life. Everyone has varying reactions to various hormones, medicines and even foods.
Because of the possible response side effects of Trenbolone, Trenbolone Enanthate is not recommended for first time users. Your first go with the hormone should always be Trenbolone Acetate, which most will prefer anyway. However, if you choose the Enanthate version your first time, run into problems and discontinue use you will still have to wait every bit of three weeks or more for the effects to dissipate. If you choose the Acetate version and run into problems, you can discontinue use and see them fade in a few days.
Methenolone Enanthate U.S.P. - 100 mg/ml/10 ml Primobolan is an enanthate esterified injectable steroid which shows mild anabolic and low androgenic properties. The enanthate ester creates a situation in which concentrations of the steroid rises and stays elevated for roughly two weeks. Primobolan is the injectable version of methenolone, the same compound available in oral form created by Schering. The injectable version is much more popular, being much more cost effective to males bodybuilders whom require a relatively high dose.
Primobolan is commonly used by those who wish to keep oestrogen and androgenic related side effects to a minimum. Primobolan is also a popular choice for cutting cycles due its mild anabolic properties which may be best suited for sustaining muscle tissue under strict pre-content dieting. Excessive subcutaneous fluids will also not be a concern due to primobolan being a non-aromatising steroid. The compound could also be added to bulking cycles to heighten the anabolic nature of the cycle whilst minimising adding to the overall oestrogen and androgenic side effects.
Androgenic related side effects are usually only confined to the sensitive individuals, or those who opt to take the larger dosages of the product. Primobolan is often regarded as a safe steroid in comparison to other products, and it is a very sought after product which reflects in its cost. A dose of 400mg a week has been shown to provide decent gains, but higher doses are common, with many claiming 600-800mg a week will provide a much better yield in muscle size whilst not causing too much in terms of side effects. As we rise the dose we can expect the androgenic side effects to become more pronounced, so its down to the user to see what dose provides fruitful when weighing up the side effects to net positive gains.
Primobolan is often stacked with other steroids to provide more pleasing results to the user. During a cutting cycle the product could be stacked with a non-aromatising androgen to aid muscle hardness whilst keeping a very defined look with little water retention. Others may find primobolan a nice compound to add to their usual testosterone course to add to the anabolic nature of the cycle, whilst not adding too much to side effects. This may be useful for those who have found their tolerance dosage with testosterone but wish to add another compound to their stack to aid gains.
Due to the high demand and cost of the drug there are many fakes of primobolan around. Pharmaceutical grade primobolan is heavily faked, but if you can get legit Schering primobolan it will be the best for your money. Otherwise, use a trusted UG product with good reports.
