Tablets: fast in, fast out
Dianabol and Anadrol for mass, Winstrol and Anavar for a leaner look, Turinabol as the mildest of the group, Halotestin and Superdrol at the harsh end, and Proviron, which is used alongside a cycle rather than as one.
Most of these are 17-alpha-alkylated so they survive the liver, which is also why runs are kept short and why two of them at once is a bad trade. They act within days, so an oral is often used to open a cycle while a long-ester injectable builds up.
