I was pleasantly surprised at how well the product performed. It did what the rep said it might do. Thanks GNC.
Due to a back injury and subsequent nerve damage I started using a prescription determine replacement. I got in the insurance donut hole and they wanted $300.00 For product. Thought I would try GNC FOR A replacement that wasn't cost prohibitive. Discussed with GNC rep, he suggested the P6 product. Right at $100.00 per month before you get the bogo 1/2 off. Plus I got more energy and my hair quit falling out. I was under nourished. I can testify that for me the P6 product made a big difference. Talk to a knowledgeable rep. I think they could help you too.

Actually works
Blood test went from 4.3 to 11.2 in two weeks. The only reason for 4 instead of 5 stars is the price. I will buy it again.

Best T booster
This is the Best T booster GNC sells. The only negative about this product is the price. However, if you are looking for results, this is the "IT" product.

The product works better than any other products that I have tried, and I have tried a few, and that is why I still use it, because it works for me.

Best test booster on the market
Great product I gained 20lbs of lean muscle! I never had a solid 6 pack until I took this product! I tried to take preformix test booster but it's nothing compared to this product!

Cellucor Spot On

Amazing Product. Worth the money
It is expensive but once you actually go ahead a try a bottle, you will understand why. Insane strength gains, fat loss, energy, overall wellbeing, and libido. Been taking it for over 4 years now and I feel amazing and my dr says I have one of the highest free testosterone numbers of any of his patients my age. He even takes it now!
