This product definitely works. I've used it for a month now and can see results.No need to spend money on the 4Life transfer factor, this one works just as good for the fraction of the price.

A good price when compared to the MLM prices out there! We use it as an immune booster when needed. D. Engle

Seems to be doing the job. It does seem very similar to 4Life TF which I took for some years. Both make my skin dry.

I'm passing through a time with weak immune system, so I tried this but didn't noticed any improvement. I think I should stick to the basic: Zinc, Ashwagandha, Glutamine and Vit C.
