6-OXO (4-Androstene-3,6,17-trione) Explained
by Mike Arnold
6-OXO was the 1st effective anti-aromatase to hit the OTC market. Originally formulated and marketed by Patrick Arnold, the chemist-guru who brought pro-hormones to the marketplace, including the original 4AD and 1AD, Patrick was the man who helped launch the modern OTC prohormone movement. Patrick has also been responsible for bringing several undetectable designer steroids to elite athletes, has been featured in bodybuilding magazines as a monthly columnist, owns his own supplement company, and is still widely respected as an authority on anabolic chemistry and ergogenic aids. With that said, we will delve into 6-OXO and explain why it is still relevant today.
