Referencing Llewellyn's Anabolics 9th ed. The pct protocol he outlines calls for 2500iu eod for sixteen days. The reason being that the testes have become desensitized tour our own LH. This dose and duration "shocks" the testes. This is supposed to hasten the process. His pct also calls for both clomid and tamoxifen as well. Dosing for clomid is 50mg 2xday for first 30 days, and tamoxifen at 20mgs qd for first 45 days.
