it can be slightly suppressive....sustain alpha would be better out of the two whilst your recovering....how long was it since you done pct? most people here prefer hcgenerate as a test booster...whilst i thought it was one of the best i tried..sustain alpha plumps my balls up more,improved my libido......its trial and error with supps....you gotta spend few bucks and find out which works best on you personally ....if your pct is more than say 8 weeks since....you could try 4 weeks dermacrine/4 weeks sustain alpha.....i use to like that little combo in between aas cycles.must admit not done it for over 18months ...been trying newer supps........but now you mention it ,them 2 worked best on me.
