Hi guys!!! I was searching for the molecular/physiological basis of the so named " BACK PUMPS ". I have not found much about it and I really would like to know the causes of these BACK PUMPS. Anyone has some good informations?? Thank you very much!!![]()

I do beleive some think it's your kidneys or some organ that is inflamed causing the pain. Are you on a steroid?
Not now! I think I will cycle BOLD 200 for 8 weeks at 800 mg/die on September but I was referring to the lower back pumps ( pain )... I am a bit worried about these back pumps...
the two most common reasons i have heard of:
1) bad form
2) AAS use - especially superdrol
do u get them on every training day regardless of what u train, or just certain bodyparts
