As a rule of thumb, most post that start out with " I have this friend" are usually a cover up for stupid activity. However, I have this friend that asked me to seek feedback on Taitropin, and Pfizer. I assume these are forms of GH going by what he said. Are these respectable products? Has anyone used them? Would you recommend them if so? Lastly, on average, what does 1000 I.U.'s cost (roughly)? He is interested in starting GH and I guess these two are available. Thanks.
