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.

Side Effects of Trenbolone Enanthate:
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. 

Estrogenic: 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. 

Androgenic: 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. 

Cardiovascular: 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.

Testosterone: 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. 

Hepatotoxicity: 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.
