They have been around for some time on multiple boards, pretty sure they are legit mate
While true (depending on location), purity is far from sufficient to determine quality. For a product to truly be pharma grade it goes through several tests outside of purity. Bioassay (potency), sterility, endotoxins, excipient testing, identifying impurities, stability testing.
The purity test basically just tells you whether it's complete shit or not, and whether it's actually GH. It's cheaper and more accurate to do a blood serum imo
