I CAN'T TELL WHAT IT IS DOING FOR ME. I FEEL NOTHING

Supplements in the U.S. are largely an unregulated industry. The FDA doesn’t test for safety, efficacy, or regulate this market at all. You do not even know whether the supplements contain what they say they contain in the amounts that they claim. In fact, you hear about class action lawsuits against supplement manufacturers all the time because of this. It also doesn’t help that there are actual counterfeits being sold, especially on Amazon, too – I was a victim of this, by the way. So, my rating scheme of supplements are largely based on the following:1) A star for supplements that are verified made in a certified GMP facility in the U.S.2) A star for supplements from well established brands with well known presence on the Internet, i.e. a well built website with large Google search results from established companies.3) A star for being independently lab tested with verified lab results as posted by the manufacturer.4) Full 5 stars for supplements being tested and or certified by USP, NSF, Informed Choice (or Sport), or ConsumerLabs for having good purity, and potency to the stated manufacturer labels. Or, if the supplement is also sold via CVS, which require all supplement manufacturers to be verified third party lab tested via USP, NSF, UL, or other verification and standards bodies.Negative stars for products in some extreme condition may be doled out: damaged products (broken seal, or broken capsules), expired products, products that are rancid (fish oil, etc…), and products that have been shown to not meet quality controls and standards as mentioned in 3). Also, if there are previous FDA warnings issued against the company and products, or pending civil lawsuits for poor products will result in 1 star ratings.My opinion on how it tastes, if I feel like it works, or what the scientific literature says about the supplement ingredients are irrelevant to the star ratings. It’s really up to your own discretion and research to figure out whether this supplement is worth using based on said research or my own opinions on it. With that said, here’s the rating and review for this supplement.Other than negative stars, I cannot delve into why this is a 4 star rating, as Amazon Vine keeps flagging my supplement reviews for inane reasons. And, I'm just going to give up on providing any meaningful review on supplements because of this. You will just need to look at what I posted above, look at my star rating, and figure it out yourself. As always, do your own Due Diligence when shopping for any product, but especially health and sports supplements.

I have been pleased with the products I have gotten from Piping Rock so far and this seems to be good as well. It is made in the USA and GMP certified so I think it is a good product. Haven't had any trouble with it or side effects.
