Gaspari does make quality products but...
I might go with Rebound XT "Reloaded"
Rebound XT, by designer labs, just has really been a tried and true PCT supplement for their steroids. It's been around for years, and many have had great success in PCT using it. Some actually use it in standalone cycles, to boost natural test and limit estrogenic effects.
I have not dealt with the "Reloaded" version however. But I can only assume that it would work better than the original. Anyone have experience with the new version?
