Bulldog, if you do a search on google, you will find a ton of people that say yes. There are quite a few testimonials and pct logs that are useful.
In my case, I did not want to risk losing my gains with an OTC PCT supplement, so I added it to a HCG and nolva protocol. It certainly did make me more horny than I have ever been before I added the nolvadex. Also, I used HCGenerate during PCT (used HCG during my last cycle at 2x a week at 500ius).
I have no affiliations with the company that makes HCGenerate and no reason to push its sales. For what its worth, I will not go through PCT without HCGenerate.
