yes winny actually cramps me up the most of any steroid. its hard for me to run. i think its cause it filters thru the kidneys and it also drys you out so much that i cramp. var did it as well, thus the only oral i run is dbol now. drink plenty of water to combat the pain and make sure your not getting backed up. alot of times what i thought were back pumps were my kidney's screaming or the winny cramping me up. as soon as i drop it i always un cramp and lose the pain. maybe drop it and see. why run something if it is hurting you. if you must run it i would drink pure cran with 2 gallons of water ed
yes its the winstrol for sure......winstrol causes nitrogen retention which causes blood and water to fiill the muscle hence the reason winstrol works well on low cals...keeps muscles full and strength up!!....but if your cals are up and your not supplementing with potassium and taurine you will get back pumps so bad that stripping the weight off the bar after bent rows or deads is so torturous!!!! my advice if you want to stick with it is plan your workout so that you don't hit rows and deads till the end of your workout so when your lower back is trashed you'll be finishing up......also...sometimes lat pulls or pullups help to relieve the tension in the middle of your session if the back gets knotted up. winstrol pumps my back and my ankles and shins like mad when doing cardio.
