A Closer Look at Trenbolone

Not too many steroids have an air of mystique about them quite like trenbolone. The bodybuilding literature is full of strong, unusual, and often-inaccurate statements about this drug, and consequently an air of misunderstanding has begun to cloud our view of trenbolone. The unusual history of this compound, including prolonged periods of very limited availability and high selling prices, has no doubt played a part in shaping the view of this steroid in the minds of athletes. It seems when anything is out of reach, overly expensive or both, people start looking at it in a different way. I therefore thought it would be a good idea to take a closer look at the physical properties of trenbolone, as well as its current state of availability and use.

Androgenic Activity

Although derived from nandrolone, trenbolone is comparatively far more androgenic than this steroid. In fact it is several times stronger in this regard than our primary androgen testosterone as well. The first contributing factor to this of course is that trenbolone is a strong binder of the androgen receptor. This trait is also characteristic of its parent nandrolone, which is several times more active than testosterone in this regard. Androgen binding is in fact further enhanced by the introduction of double bonds in delta-9,11, which makes trenbolone an even more potent agonist of the androgen receptor than nandrolone.

Perhaps more significant though is the fact that unlike nandrolone, the strong receptor binding potency of trenbolone is not diminished in androgen sensitive tissues by 5-alpha reductase. Trenbolone does not seem to undergo 5-alpha reduction in humans to any appreciable degree at all, which is evidenced by the fact that the major urinary metabolites of trenbolone all possess the original tri-en structure with an intact delta-4 group. So trenbolone retains its original potency as it enters cells in androgen target tissues with high 5AR concentrations, as this enzyme is not affecting it. These factors work together to allow trenbolone to be a potently androgenic steroid, instead of a primarily anabolic one in nature like nandrolone.
Progestational Activity

It has been reported in other bodybuilding literature that trenbolone does not exhibit any activity as a progestin in the body. I am not certain where this belief originated, as trenbolone does appear to exhibit the classic progesterone receptor binding ability that is characteristic of nandrolone and its derivatives. One study looking at the bovine uterine progesterone receptor for example found trenbolone to be a very potent binder, startlingly even more so than progesterone itself. Another looking at the binding of various compounds to the androgen, estrogen, progestin, mineral corticoid and glucocorticoid receptors found trenbolone to be a more potent binder of the progestin receptor than nandrolone decanoate, a steroid normally noted for its usual activity in this regard.

What does this mean for trenbolone? I don’t think it really means that much. Trenbolone clearly doesn’t cause gyno, water retention or fat buildup, which one might attribute to estrogenic or progestational activity. So whatever slight action it does have as a progestin on paper doesn’t amount to all that much in the real world. The absence of estrogen may be a significant factor, as progesterone is believed to cause gyno by enhancing estrogen’s stimulation of mammary gland growth. Perhaps when trenbolone is taken with other aromatizable compounds it could affect a person’s sensitivity level to gyno and water/fat retention. This seems logical, at least in a technical sense, although admittedly I have seen no evidence to support this.

Mass or Cutting Agent

The potently androgenic and non-aromatizing nature of trenbolone makes it an extremely effective hardening and cutting agent. In fact, it is thought of as unmatched in its capacity as a body-sculpting steroid. Many competitive bodybuilders similarly find it indispensable to any good pre-contest cutting stack. For this type of purpose I doubt another steroid would serve you better. Many people do additionally find they make very good muscle gains with trenbolone. It is a potent muscle-builder, although we should probably not consider it an ideal mass-builder when used alone. The absence of estrogen is an important factor, as this trait seems integral in this type of steroid.

This probably has to do not only with water retention but also interactions between estrogen and muscle glucose utilization, GH release and androgen receptor proliferation. Today we are finally starting to understand why this hormone is needed for optimal growth. Trenbolone is probably still the most potent muscle-building agent of all the non-estrogenic steroids though, and admittedly is quite unusual in its potency in this regard. But I would still think that if mass were the goal and you were choosing only one steroid, testosterone, Dianabol or Anadrol would be more productive every time in terms of overall size, weight and muscle mass gain.

Cycle and Dosing Info for Primobolan

Although Primobolan (GP Prima 100) is a quality steroid, as said it is rather week. Also due to the fact that it contains (in injectable form) an enanthate ester, anything under 400mg per week is rather a pointless use of GP Prima 100 and a waste of money. Generally with AS, more does not always mean better (due to side-effects and other issues), however in the case of GP Prima 100 more does definitely equal better. If stacking GP Prima 100 with testosterone, 400-800mg per week will be an effective dose, with obviously the higher doses being the most effective. GP Prima 100 will have two main effects in such a stack. Firstly it will seem to amplify the effects of test, so 500mg of test enanthate may seem like 750mg or more. Secondly, Primo is very forgiving with one's diet. Quality muscle can still be obtained at a steady rate even with one's diet being off from time to time. However, with a spot-on diet, Primo and test will work wonders.

For those who would want to use Primo on its own or without test, you would really need to use a minimum of 600-800mg per week. If you can afford it, 1000mg per week of Primo will highly reward the user. Some people often ask about using Primo with Trenbolone. This can be done, however without test one must realise that you are likely to be quite shut down, and it is likely you would need some sex medicines as well as HCG. Despite this, for those that want a test-less cycle, Primo and Tren is a great cutting cycle. My ultimate cutting cycle however is one that incorporates Primo, Test Prop and Tren Acetate. Another very good cutting cycle that is test-free would be Primo (600-1000mg per week) with Anavar (60-80mg per day).

Due to the enanthate ester that is attached to the Methenolone base in Primo, it really should not be run for less than 8 weeks. In my opinion, I would run Primo for a minimum of 12 weeks, also bearing in mind that the Primo really kicks in at about weeks 5-6, where a real fullness of muscles is experienced. Primo is also useful at a high dose for those who use higher doses of test and experience appetite loss from this. Primo doesn't cause such appetite loss, thus when bulking this can give a chance for diet to be spot-on. Primo does suppress and shut you down as said, however it is roughly about half as suppressive as test, so a 12 week Primo cycle would shut you down similar to a 6 week test cycle. For this reason, Primo alone can be run up to 20 weeks without fear of a very difficult recovery in PCT.


Due to the enanthate ester, PCT should be run approximately 14-18days after last Primo injection.

Here are some example GP Prima 100 (Primobolan) cycles:
Test-free cycles

    GP Prima 100 600-800mg pw weeks 1-12; Anavar 60mg ed weeks 1-8
    GP Prima 100 600-800mg pw weeks 1-12; Tren Ace 75mg eod weeks 1-6
    GP Prima 100 800mg pw weeks 1-12; Masteron 400-600mg pw weeks 1-14
    GP Prima 100 1000mg per week up to 20 weeks (expensive)

2) GP Prima 100 cycles with Test

    GP Prima 100 600mg pw weeks 1-12; Test enanthate 500mg pw weeks 1-12
    GP Prima 100 600mg pw weeks 1-12; Test prop 100mg eod weeks 1-14; Tren enanthate 300-400mg pw weeks 1-10 (Superb cutting cycle for advanced user)

There are many other different cycles you could do; these are just a few examples. Generally, the amount of GP Prima 100 you will use in the cycle will be down to how much you can afford, and how many injections you mind doing. As said though, generally with GP Prima 100 , the more you can do, the better, but a minimum amount would have to be no less than 400mg/week.

Everything You Need to Know About HGH

Human growth hormone can turn back your body’s internal clock, helping you rapidly build muscle, slash fat, and increase libido, all while sending energy levels through the roof. but when it comes to discussions on hGh, there are often more questions than answers. to help you decide whether you need hGh, check out our straightforward Q&a, which answers some of the more commonly asked questions and learn how you can boost your own natural levels of this powerful anabolic hormone.


What is human growth hormone?
The body naturally produces growth hormone (HGH or simply GH) in the pituitary gland, and, as its name implies, it is responsible for cell growth and regeneration. Increasing muscle mass and bone density are impossible without GH, but it also plays a major role in maintaining the health of all human tissue, including that of the brain and other vital organs. When secreted, GH remains active in the bloodstream for only a few minutes, but this is enough time for the liver to convert it into growth factors, the most crucial of which is insulin-like growth factor-1, or IGF-1, which boasts a host of anabolic properties. Scientists began to harvest GH from the pituitary glands of cadavers in the 1950s, but didn’t synthesize the first HGH in laboratories until 1981, with its use as a performance-enhancing drug becoming popular shortly thereafter.

How much GH do I produce naturally?
Healthy adult men typically have just less than 5 nanograms per milliliter circulating in the blood. Healthy females can produce about twice that amount for child-bearing purposes. Levels for both sexes peak during puberty and drop sharply starting in the early 20s.

How can I learn if I have a GH deficiency?
Ask your doctor to perform a GH test. You’ll need to fast for a simple blood test that is not unlike the one administered during an annual physical.

Where can I get HGH?
HGH can be obtained only through a doctor’s prescription in the United States. Anti-aging clinics like Braverman’s specialize in identifying GH deficiencies and making the diagnosis. For those who lack GH sensitivity, a doctor may prescribe pure IGF-1. You can also buy HGH online, but only from reliable and trusted steroids shop like http://www.halfpricegear.com

How To Get The Most Natural HGH Secretion

One of the best natural ways to get the most natural HGH secretions for your genetics is to workout at a high intensity for periods no longer than 45 minutes. This is according to the Bulgarians Olympic power lifting studies. But it is believed that you should be monitoring your affected muscles for the amount of blood gorging they have.
The higher your testosterone and growth hormone levels, considering your diet and rest is optimal as well, you will be able to maintain a pump for longer. You will also have a fuller pump!
Cardiovascular health is crucial to saturate the blood capillaries with oxygen. Start with the goal of finishing your workouts around the forty five minute mark. If you feel that you lose your pump before this time is up, then before you completely lose your pump, quit to keep as much of the pump for as long as possible.
On the other hand if you still have a good pump at the end of the forty five minute period I suggest you keep pushing yourself until you feel your pump starting to
subside. This way you can get the most amount of growth without overtraining in the least amount of time possible.

Pushing yourself after your pump has subsided is a double edged sword cutting your progress in half!

To improve your progress you may use HGH injects.
