6-OXO was shown to increase testostrone levels over 250% over baseline in a clinical study at a university..May not work as well as gear though..
user feedback has been good for 6-oxo...I hear that 600mg daily for 6 weeks produced results equivalent to 200mg test week..The only downside is the cost..You'll need rougly 5 bottles to complete the cycle..At 33 dollars each..So that cycle will cost you 165 dollars...Yes more expensive than real gear..However, it's a safer alternative for many that are worried about steriod sides and worried about the leagality issue.
