Sci Fit continues the search for the ultimate pro-testosterone formula in ES3 Stack. This triple action stack is unmatched in potency and effectiveness. The name ES3 is two part in meaning. ES meaning estrogen suppressant, and 3 illustrating the three prong approach. Sci Fit’s ES3 Stack elevates aromitase inhibitors to a whole new level: 3,6,17- A-Trione is well known as the first and most popular aromitase inhibitor. Reducing aromitase enzymes results in less estrogen. Less estrogen promotes more free testosterone. Preliminary research suggest as much as 300%+ more free test! 6,17-keto-eticholeve-3-ol-tetrahydropyranol combines ether technology with aromitase inhibitors. The result is greater bioavailability with long lasting effectiveness. 3,17-keto-etichol-triene is the latest in prohormone replacement effectiveness. This new “keto-triene” is proving to be the new standard in estrogen suppression. Initial reports indicate this fast acting agent to be as much as four times as strong as its “trione” predecessor. ES3 Stack additionally incorporates the supplement enhancing DHB for maximum overall absorption. Stack the new ES3 with TZ3 or T-500 and experience muscle building with fat shredding results never thought possible in the post-andro era! Flavors:None 60 and 120 Capsules
