Important caveat: there are no completed human efficacy trials showing that GHRP-6 builds muscle, improves recovery or slows aging

W126A - site-directed mutagenesis, H-site mutation, the mutant shows increased activity compared to the wild-type enzyme W234K - site-directed mutagenesis, isozyme GST T1-1, the mutant shows altered substrate specificity compared to the wild-type enzyme Y108A - mutant enzyme shows 58% of the wild-type activity with 1,2-dichloro-4-nitrobenzene as substrate and 37% of the wild-type activity with 1,2-epoxy-3-(p-nitrophenoxy)propane, 2% of the wild-type GSH peroxidase activity towards cumene hydroperoxide and 163% of the wild-type steroid isomerase activity towards DELTA5-androstene-3,17-dione Y108F - mutant enzyme is as active as wild-type enzyme with 1,2-dichloro-4-nitrobenzene as substrate and shows 7% of the wild-type activity with 1,2-epoxy-3-(p-nitrophenoxy)propane, 77% of the wild-type GSH peroxidase activity towards cumene hydroperoxide and 149% of the wild-type steroid isomerase activity towards DELTA5-androstene-3,17-dione
