Technical Write Up:
This compound is like sliced bread to the supplement industry. There are many different health benefits to come from resveratrol, but we picked it up for one in particular. Resveratrol is capable of modulating estrogenic receptors as well as controlling aromatase, giving it that One Two Punch for estrogen control. Research has shown its estrogenic modulation capabilities to increase sperm production by stimulating the hypothalamic-pituitary-gonadal axis. 
Quercetin & Piperine:
Well we've got our pretty sick post cycle therapy stack going here, but there poses one small problem, and that's absorption and bioavailability. Icariin and Resveratrol do not have the greatest bioavailablity in all the land so we gave them a little help with Quercetin and Piperine. Quercetin is used because it is the most potent natural inbitor of estrone sulfanase which degrades compounds like resveratrol.  This makes not only aids in absorption, but enhances antiestrogenic activity. Piperine is another addition because it enhances the ability of your intestines to absorb nutrients and phytochemicals.  Additionally, piperine may also inhibit the glucuronidase enzyme, another enzyme which degrades resveratrol.
