Generally if your endo is any good at what he does, he'll explore the GH option with no problems, and will have no issue scripting you IM test with an AI. GH is a bit harder to get a script to, but if all else fails hit up one of the male clinics the specialize in TRT/HRT. They're a bunch of fucking idiots usually, but they write GH and Test scripts like it's nobody's business because that = $$ for them.
Hell I think noodles gets fuckin GH, Test, Adex, and Var all from his pharmacy
