Yeah, Shen Min's only claim to fame is the newer formula which "boasts" Saw Palmetto and beta-sisterol. Neither have been found (that I'm aware of) to inhibit scalp DHT, and both are available in other supplements.
I think you'd get any possible benefits from beta-sisterol from including soy products in your diet, and Saw Palmetto? -- well, I don't think it works, and if by any chance it did, it would be in a similar way that Propecia works, same sides and all. I think you're more likely to just get sides with Saw Palmetto without actually getting benefits for your hair. Great for the prostate though!
