Any time the body gets an exogenous compound it will...
A: develop a tolerance
B: develop a dependance. (In other words, supressive).
It's biology 101.
Who was it that was breaking my balls about this? -- saying that some Medline study showed proviron wasn't supressive so it was okay to use as much as you want for as long as you want and how I don't cite scientific studies and blah, blah, blah, blah...
Simple biology my friends.
Proviron is cerainly LESS suppresive than anabolic androgenic steroids and is okay when used to cushion a crash, and it's actually an under rated anti e. But there are no free rides. People must begin to accept this, but some are still stuck in the "Fonz" era where as you can cut and paste a random study that supports your belief you can do whatever you want with no consequences.
This is one of the concepts behind UNLEASHED. A supplement that lowers SH BG like Proviron with no supression -- because it doesn't ADD anything. It just blocks the enzyme which constricts free testosterone from being released. Pretty clever actually.
