If you google search “Biotest Fahrenheit”, this site, which is the official site, doesn’t come up.
I would suggest checking it out if you have female clients or females in your life in general who want to improve body composition, but would be hesistant about taking Maximum Strength HOT-ROX, something so powerful, the general public can’t get it.
I can’t speak for it’s efficacy because from what I can tell, nobody’s ever taken it, and there’s no way to get to the official site. Chalk one up for marketing. But it’s Biotest, so it’s probably remarkable and worth a look.
