Takes two weeks to kick in
Took about two weeks to start seeing results but I feel stronger now and am lifting heavier. The supplements seem to be doing their job now.

I have been using you guys for so long that I can’t even remember when I started using your products. Every person that I’ve worked with over the years has been really good at getting me great discounts cutting back my shipping charges free merchandise not to mention the fact that the supplements work.!!!!!!! with my level of training my aggression with the training and your supplements I have made so many changes in such a quick period of time that people literally think I’m on trend or something like that.

I appreciate the prompt service of confirmation of order and shipping out and delivery. It is always good when a company sees you as a valuable customer and want to earn your service.
