yes they had access to them both. the rhesus monkey hormone was used actually more often than the cadeavar stuff because they assumed it was safer ( you might get whatever the human died from when you used the human stuff) dont really know how well the rhesus stuff worked if at all. seen some athletes who used it in other sports and it did make their hands and face change alot. ( and no not from dieting) if you had access to a university where they did studies you could get both kinds. and like anything else the black market was widely available back then as well.
