there are a few threads on this try searching.. feedback seems good but the dosage is all screwed up with the halo and phera.. i think its around 25 of halo and 25 of phera (i could be wrong), so taking two pills would be too much phera. Since 50mg of halo is what most people run, i would suggest buying another halo clone along with this so u can get a better dosage scheme (1 pill of gxl original hd + 1 pill of halo clone = 50mg hd and 25 mg phera). also i hope u have your post cycle therapy in line and your support supps in check as well.. good luck
