You can start sooner than 5 weeks if necessary. You shouldn’t get estrogen sides in theory as your not injecting testosterone so your levels will drop and therfore there’s less to convert to estrogen. When hcg goes in estrogen spikes hence the aromasin and or nolvadex. But yes you have the correct pct. I’d suggest some of the jps natty range to help levels when you have finished.
thank you for the reply, In what circumstance can i start earlier than 5 weeks, by a blood test with good markers?
