The injection is naturally regarded as having a higher bioavailability. It is an enanthate ester which is quite long-acting. Because it by-passes hepatic breakdown on the first pass, it also has a higher survival rate. The tablets are in a short-lived acetate form. Methenolone is not 17-alpha-alkylated, but 1-methylated for oral bioavailability.
Primobolan Depot will not aromatize in the body, therefore estrogenic side effects such as bloat should not be a concern. Bodybuilders with reasonably low bodyfat will notice an increase in definition and lean muscle mass.
One side effect that a lot of people are not aware of with Primobolan is its effect on the kidneys. It does not directly harm the kidneys but since it’s so anabolic, it keeps an enormous amount of protein (nitrogen) recirculating throughout the body. That’s great for your muscles but the kidneys still have to remove the waste and after a while it can start to be a strain. So if you’re thinking of doing 500 mgs of Primo a week as a bridge, or as an adjunct to HRT thinking it’s a “free ride”, think again. Primo isn’t harsh, but it is powerful. Do not underestimate it and do not think it can’t do any harm if overdone.
