Primobolan / Methenolone is a very mild anabolic.
The androgenic activity of this compound is considerably low, as are its anabolic properties.
One should not expect to achieve great gains in muscle mass with this drug. Instead, Primobolan® is utilized when the athlete has a specific need for a mild anabolic agent, most notably in cutting phases of training.
It is also a product of choice when side effects are a concern.
A welcome factor is that Primobolan® is not c17 alpha alkylated as most orals are.
Due to the absence of such an alteration, this compound is one of the few commercially produced orals that is not notably stressful to the liver.
While liver enzymes values have been affected, in some rare instances, actual damage due to use of this substance is not a documented problem.
Unfortunately the 1 alkylation and 17-beta esterification of Primobolan® do not protect the compound very well during first pass however, so much of your initial dose will not make circulation.
This is obviously why we need such high daily dose with the oral version of Primobolan®.
Primobolan® will also not aromatize, so estrogen related side effects are of no concern.
This is very useful when leading up to a bodybuilding contest, as subcutaneous water retention (due to estrogen) can seriously lessen the look of hardness and definition to the muscles.
Non-aromatizing orals are therefore indispensable to the competitor, helping to bring about a tight, solid build the weeks leading up to a show and of course without excess estrogen there is little chance of the athlete developing gynecomastia.
Likewise there should never be a need for antiestrogen use with Primo.
For example, in one stud more than half of the patients receiving only 30-45 mg noted a suppression of gonadotropin levels of 15% to 65% a.
This is a dose far less than most bodybuilders would use, and no doubt increasing it would only lead to worse suppression.
One would therefore still need a testosterone stimulating drug like HCG or Clomid®/Nolvadex® when concluding a low-dose Primobolan® cycle, unless a deliberately small dose were being used.
Suggestive dose 75-150mg daily.
