Supposedly dianabol. SO if you do that you'll look just like Arnold.
A lot of guys don;t realize test was NOT a popular choice back in the 60's. Nobody used it. Dianabol was the solution to test side effects. (Supposedly).
Yup
they did have fantastic genetics but the idea that you always have to use test no matter what else you use is plainly absurd. Use test if there is a real risk that your libido will cease functoning. Use enough to counter this but no more. There is very often a better option in terms of the gains vs. sides ratio than test. Besides you don't keep very much of what you gain from test. Test is a formidable hormone but it should be used with great caution IMO.
