when I did Sustanon some years ago, I waited 3 weeks after the last pin to pct. I don´t remember anything specific about that time so I think It went all good. Did blood work about 3 months after that and I was ok. I always believed that with test C and E, wait 2 weeks to pct, taking in consideration that half-life is about 7-10 days, you just wait for 14 days. Now I found here that mg per mg, it builds up in the body all through the weeks and it takes more time to leave the system. I don´t know if this does make sense because there is a reason you split injections two times per week instead of just one, in order to keep blood levels stable. Honestly, fuck if I know. I will do test blood work on day 15 after the last pin and then will see.
