There is a big difference between regular Yohimbine and Alpha Yohimbine.I had a feeling it was something along those lines. I remember seeing it pop up a lot along side tribulus, goat weed, and maca for libido etc but lately I've seen people suggesting a few other positive benefits from it
I think you're thinking of regular Yohimbine in correlation with it being alongside Tribulus, horny goat week, etc.
Regular yohimbine, like in our Yohimbine 2.5 product is great for fat loss and erection quality, but some people have a hard time taking regular yohimbine because it makes them feel shaky or feel bad (myself included).
Alpha Yohimbine is a more potent form that can be used by most people that can't take regular Yohimbine, and its great for energy and fat loss.
If you're still using Pump Addict Ultra Hardcore, there is a small dose of Alpha Yohimbine/Rauwolscine in there.
