My research has led me to believe that high doses of test also slow collagen formation, even when taken with collagen building gear such as deca or eq. I've posted several times about this btw. This is actually the main reason I avoid test. EQ is pretty much the staple in all my cycles. EQ/tren/prov is good, and so is eq/deca/prov. If I do throw in test, it's never above 150mg/wk for normal test functioning. With eq as the staple, I avoid test sides, and also accelerate collagen formation with each cycle, especially with deca/eq. I don't do any orals either except proviron. Tbol or anavar would be good additions to these cycles if you were interested in orals, but I would definitely avoid orals like anadrol or dbol; that would defeat the purpose.
