Like any hormonal designer ph/steroid it needs a PCT.
lots of threads out there
:gotsearch
Or better yet, OP - your PM has been answered.

:woohoo:
But for public reiteration:
Yes, you need a PCT. We recommend aPCT (AX's Advanced PCT) as it is one of the most potent AIs on the market. Can you use 6oxo? Maybe, but I don't know why.
4 or 8 weeks? 8 is out because it's too long. Better question is 1 or 2 bottles. The bottle will last different amounts of time depending on your dosing. Thusly:
1 bottle:
-up to 220lbs
-4/day = 22.5 days
-220lbs and over
-6/day = 15 days
2 bottles:
-4/day = 45 days
-6/day = 30 days
Longer or higher than that requires more of a PCT and can get a bit more complicated. As long as you don't go nuts with it, an OTC PCT is all you'll need.
Also, no support supps necessary. No methyl, nill for liver toxicity (or close to it anyway), so no protection needed. Which leads me to what will undoubtedly be my best analogy today:
Support supps for 3-AD is like jerkin off wearing a condom. It's unnecessary, could be done, but just sounds as funny as it might feel. :fool2:
Thank you, I'll be here all night! Leave tips in the jar on the bar, please. :cheers:
