Oral dosing I've used up to 300 mg. per day of 7-Keto but I got a much better benefit out of Reduce XT, which is 7-OH DHEA - better fat loss and better mood support benefits at 150 mg. per day.
Topical/td dosing - I love FL7 and have done 200 mg. per day. (4 ml). I space it out 2 ml in the morning and 2 ml at night.
Seeing your join date in 2005 makes me think that you probably remember FL7 from the Avant days and Xtreme Performance Gels brought back several of the Avant products - FL7-7-OXO Gel, Napalm Xtreme, Lipoderm Xtreme, and Ab-Solved.
