I've never had any problems with winny, then again I've never used more than 30mg/day till this cycle. Fina alone I can handle up to 100mg/day, above that the pumps in my calves and shins prevent me from even walking at more than a moderate pace. Fina + dbol and you can forget deadlifts. And MY GOD, 600mg/week of tren enanthate and I had to drop it 4 weeks in b/c I couldn't train more than 3-4 sets of almost any exercise without my ROM dropping to maybe 70degrees. And BBF... these are from PUMPS, not cramps bro, I take several times the RDA of all those minerals and electrolytes, that has nothing to do with the pumps. Now if I had overdone the lasix those would help with a little water, but otherwise, the pumps are there to stay with those drugs.
