12 weeks not going to do that again. 6-8 weeks tops from now on. I've found that for me, gains seems to appex around that time and seeing as how that's around the time you get shut down, might as well try to re-establish one's HPTA to try and keep as much of those hard earned gains as possible.
I think it was back around 89 where i lost my contact on deca. You know the lil 1ml. organon vials. so i ran test for a good year. Didnt bother much cause it was only around 500 a week.
I don't know if you saw my post about a guy I know who runs a gram year long, when he wants to "cycle" or get gains, he bumps it up to 2500mg/wk. He told me as long as he stays on HCG with it, he's fine. Good luck with that
