10 weeks test e, finished with sust, start pct?

I am on a 12 week course, i started off with test e for 10 weeks at 600mg and then the last two weeks i hit sust 325. When should i start PCT? 2 weeks after my last shot, or 3 weeks?

I will be doing, Admin's medium pct protocol which consists of clomid 100 mg day 1-7. HCG 500iu from day 8-26 eod and nolvadex 20mg day 8-37

2 weeks should be fine, if you want to maximize your results stack some short anabolic at this time, dbol, winstol, var, test suspension, etc. Run it till the day you start PCT, this way you move straight to recovery

thanks! am on winstrol at the moment!
