taurine doesn't do fukall. at least not for me. ive only felt backpumps while using 17aa steroids or pro-hormones...never experienced them with anything else. Actually thats not entirely true because I never experience them while using dbol, dbol being the only 17aa steroid that did NOT cause them for me.
superdrol,
halo, phera,
m1t all gave severe back pumps. When I asked ppl about them, i got different answers...the most sensible
one claiming that androgen receptors located in the kidneys are responsible for augmenting the stimulation of red blood cell production, increasing concentration of hemoglobin, thus increasing BP. I have asked alot of ppl, did my own research and believe the regulation of erythropoiesis, and the elevated workload put on the kidneys (to produce erythropoietin)...teamed with elevated BP is the cause of lower back pumps.
...the only reason I can think of that dbol doesn't cause mylower back to cramp and 'pump' is because of its relatively low rate of binding to AR?
