Not for beginners, I'll tell you that. It is what it is -
~Testosterone Propionate
~Trenbolone Acetate
~Drostanolone Di-Propionate
It will have the characteristics on all of these compounds. You should really look up on these more. I would strongly suggest something a bit simplier, though I am confused as you say 'in your experience' Diamond is good, but come off as having little to no experience - not a slam at all, just searching for more clearification. Also, isn't Diamond pretty new?
Anyway - What are your goals? What has drawn you to this stack in particular? Etc.
Personally I find it to be a phenomenal stack. I would add more Propionate to it myself or some low-dose dbol: shoot 1ml of it everyday and .2ml Propionate or 20mg Dbol everyday. Prop/Mast/Tren at 50mg/day with 20mg/day Dbol is heaven for someone with experience.
