Yep, it's good stuff.
I've been very conservative with it - only 5mg per dose - takes a few hours to kick in.
I don't know whether it does much for recovery time with me - but (1) I'm an old bastard, and (2) it's been a long time since the missus was up for seconds straight after - so I don't have much chance to try it out (twice).
I think that, in addition to its stiffy-enhancing value, it does, over time, make the membrum virile actually bigger, even when in its resting state. Probably because it swells it up more than normal when turgid.
Is that your experience (or anyone else's, who has tried this, or V)?
As for side effects, I haven't noticed any myself - although if I were to go up to 20mg a pop, I might.
