It seems I just replied to your other post. what do you mean by TTM? I doubt that you need to run Tren and Drostanolone now. Drostanolone is when your body fat is lower than 13%. Tren is for competitors or at least when you have lots of experience with steroids. Winstrol is for pre-content or serious cutting cycle. again, when you have enough experience. I would say that if you haven't used steroids in 10 years - 300 mg/week of Testosterone should be enough.
About PCT with or without HCG - what are your T levels without gear? HCG is not always necessary - it varies from one person to another. generally, people who notice testicle shrinkage uses HCG, or those who want bigger sperm loads.
