If I have a 700ng test level this is roughly 7mg my body produces a day. Say 1 mg produces 100ng roughly supplementation testosterone just two mgs (give or take)oral vs topical absorption could easily increase blood levels without suppression and staying under natural production. My theory is suppression happens when body builder's use 200 500 1000 mgs of test a week (hundreds of times the production people). Company's should be all over a low dose testosterone product to study for testosterone blood increase while keeping the hpta axis and fertility uneffected. However with testosterone so cheap likely no interest @haidut is my math of 1mg per 100ng accurate like the 15 mg 1500 ng men with too high testosterone likely with tumor. One shot a week with so high dose no wonder there is aromatizing and suppression. This dose is likely the same with dht and dhea as benefits are in a low dose range just to give the body raw materials as the male body in today's environment lacks the health and energy to produce optimal androgens.
