you don't want to run hcg in pct... the most optimal way to protect what your aiming for on cycle is to start with hcgenerate ES... lead that into running hcg, which you will blast before pct... running hcg too long can do way more harm than good... 2-4 weeks of hcg is plenty... ive found the most optimal way is running hcgenerate es 8 weeks... then blast hcg two weeks before pct...
