Oh Jesus Christ! Am I the only person here old enogh to answer this? I was training in the 70s... but I didn't start juicing till the early-mid 80s. For the most part the drugs back then were very basic. For orals you had D-bol as king but people took much less...3 tabs was considered normal... anavar was available and cheap comparatively ($20 for 100 tabs... and 10 mg was considered a good dose) and anadrol for the monsters. Injectables were very simple: there was Deca as #1, with Sustanon and a couple tests (test suspesion for the power lifters) and occasionally primobolan, winstrol, and equipoise. Other exotic stuff did show up, but for real availability you were always looking at the same three Deca, D-Boll and Test.
Most interestingly though are the drugs that were there then that they no longer have. There was some bootleg company with a name like BDN (help me out if you remember). They prebottled their own mystery juice... and you gave your self a couploe shots a week without ever knowing what was in it. It was probably just a mix of deca, test, primo, and equipoise... but it was legendary stuff at the time and everybody loved it.
