I'll be starting a cycle of Axio Labs Test Cyp at 400mg/week for 10 weeks. I'll use Nolvadex and Clomid as my pct, I can get HCG also, I'm just not sure how much hcg I should use. Some people say 500iu per week meanwhile other say 1000iu per week. How much would be best and how long before pct should I stop using HCG? I can also get Letrozol but its very expensive, is a AI really needed at 400mg/week cycle?
