Dosages:

Primobolan is usually injected several times a week since a cc contains only 100 mgs. ( This is due to a heavy molecular weight. Only so much will “fit” into a ml of oil). It’s active for approximately 2 weeks. Anything under 200 mgs a week will not show a tremendous difference but once it goes to 400 mgs, that’s when the magic usually begins. Also due to the molecular weight, Primo tends to be a painful shot. Not bad going in, but the next day you can expect some soreness.

Arnold Schwarzenegger was known to love Primo and to use 100mgs a day, which by today’s standard is quite conservative for a pro but back in the 70’s it was considered outrageous! As mentioned, Primo needs a more androgenic compound to truly get the maximum benefit so an additional steroid is often used and Arnold was thought to maybe use 50 mgs of d-bol a day, which was also pushing the envelope at the time. As little as 200 mgs of test will suffice to maintain a favorable androgenic environment. (Though most people use more, which is essentially more than they need. At a certain point, the risk/benefit ratio becomes unfavorable).
