You need to read a lot more! Because if you don't know even the basics you WILL run into trouble and then don't know what to do...
Sad but true...
Epistane is a legal designer steroid, so it's real stuff as in an active steroid that does not need to be converted and you can buy it online, legally for now.
PCT = POST CYCLE THERAPY
Reason for pct is that your body will get "back to normal" and start producing important hormones, such as testosterone etc.
Usually guys use these alone or in combination: clomid, nolvadex, hcg, arimidex. letrozole, femara etc...
But since you keep asking about OTC stuff, i presume you can't get any of these so after your "cycle" use either novedex xt or formadrol extreme.
Use the Epistane for 6 weeks starting at 10 mg and you can go all the up to 40 mg per day, anymore than that, you should not need. After that take one of legal OTC pct products for additional 4 weeks.
GOOD LUCK!
