for the 1st guy, you think his test gear is crap?
There is no test in his stack but there is likely some other AS in there in unknown amounts. I wouldn't trust the gear he has.
Van, now I'm confused. What effect does Provirion have on SHBG? Do you want it lower or higher? Lower correct?
Yes the common idea is to want to lower it. Proviron lowers it, or preferentially binds to it leaving the test in unbound state, but most don't know all steroids lower SHBG, including testosterone, in a dose dependent manner. I don't see a need for Proviron for this reason as any stack will leave you with low SHBG anyway.
Like tbombz said you may not want to lower it since free test is metabolized faster and bound T may be able to exert effects. It's a topic you could debate further and I don't know the answer.
