I know this may sound stupid BUT !! What I did to counter my back pumps from certain orals is.. take 1 gram of Taurine, 2 tums, plus my Oral.. and guzzle it with a sugar free RED BULL.. I dont know why I decided to do this but ever since I started doing it exactly like that my BACK PUMPS ceased to exist.. it was the GREATEST thing in my AAS history man.. lol..
