Hey fellas....jus wanted to say this is an absolutely amazing site...with a wealth of info...wish I bumped into it earlier.

My question is...do DHT derivatives, like Proviron , inhibit the Hypo-pituatary pathway via negative feedback like straight testostrone. Hmm I know this is probaly a very "dumb" question...but I am "newbie"so plz bare with me. Hmm I tried scimming through the educational threads but I couldn't find my question specfically answered. Perhaps I missed it.

And also I thought I read that most oral steroids have a half life of say 3-5 hours. Now if Proviron doesn't have a posistion 17 alkylation does this mean its half life is more likely shorter?

Thanks in advance.
