I just had a look at a supplements site and read some reviews, although it appears to be for the older formula. A lot of negative stuff, particularly complaints of rapid heartbeat, acne, headaches. Although some people were claiming mass gains. Anyway, ingredients are below. I'd never heard of DVTHF:
Proprietary Matrix 727mg:
Basella Alba Extract, Nettle Root, (-)-3,4-divanillyitetrahydrofuran (DVTHF), Bitter melon Extract, Resveratrol, Conjugated Coleonol Extract.
