I became skeptical about this company when I discovered that the product DHEA DOESN'T HAVE ANY EFFECT which is a recent discovery.. I find the Walmart brand way better and very effective. I also became skeptical when I discovered that the vitamin c had little effect on my sinuses even when I took high doses. Now behind those products failing me I'm very doubtful about everything concerning their supplements, they seem to be of a very poor quality and I've spent a lot of money with them. I won't buy anymore vitamin c or ANYMORE DHEA BECAUSE I DON'T FEEL ANYTHING FROM THE PRODUCTS ABSOLUTELY NOTHING. I JUST THINK I WASTED ALOT OF MONEY. The tongkatali I brought loss it's potency. I was still tired after taking their men's vitamin and minerals, I'm now doubtful about the mineral complex I purchased because after taking it for a few months now, I still am without the spunk that should come from these mineral supplements. I'm going to back up and not buy as much as I use to and evaluate other companies.. Walmart happens to be actually good on dhea absolutey. I feel let down especially after I supported these people.
