Hcg is ok, I personally only use the last 2 weeks of cycle and for 2 weeks after my last test enanthate shot, leading me into my pct....
the newer thing is HMG, it stimulates not just the lh, but also the fsh post cycle, and the newest thing is triptorelin, which i am looking into big time right now...Soon hcg will go the way of arimidex, and nolvadex...IMO..... Things are moving fast in the pct world these days...
