Sometimes some people dont feel pumps like others. and pumps from while you are on steroids, will not stay after for the most part.
you could try a pre-worout or "pump" compound supp like GPLC or even try taking some extra arginine for pump (AAKG type if you can)
Alot feel the pump products are over hyped, but they might help you out, the thing is nto buying over hyped or priced crap.
T-911 has yohimbine in it and that will give you strong bonders and pumps when working out.
I use/d it myself from time to time.
its from LGSciences and also ASGT is a nice pre-workout also.
YEs I rep them but these 2 products I do think can help you.
I also rec getting bulk AAKG from nutraplanet or something of that sort.
Feel free to PM me if your unsure and ill send you some links to there site for what I am talking about. (incase you dont know)
Good luck!
