I think the gyno problem is attributed to the high level androgen drugs being used today (testosterones) because they are much easier to get. In the 70s and 80s (from my experience and I trained with many of the pros), the primary drugs used were Deca-Durabolin, Primobolan Depot, Anavar, Dianabol, Winstrol and Winstrol Depot with Deca and Dianabol being the favorites. The drugs were real pharmaceutical grade and relatively cheap. My favorites were Primobolin Depot and Dianabol, which work extremely well for me. Ciba-Dianabol was $20 and bottle and Primobolin ampules were $4. And moderate doses. Fortunately I never experienced any problems and I never knew anyone that did.
