Best Pill Form on the market
Super pure and effective tablets, only have to take 1 vs 2-4 of other brands for same MG but then again probably more cause this ones purity. Kicks in super fast 15 mins and you get the peak 30-45 mins in

Effective, easy on the stomach
Just waiting for this horse pill to kick in. They smell like an old bottle of yellow lime Gatorade. They have a coated texture that is slightly shiny but also is like white/off white egg white, so you've got these pills that look old, but new. I looked at all the other pictures and videos in the other reviews and my pills look a lot better than theirs so I'm taking my chances. Maybe they started putting cotton in the bottles but I could see how they could crumble away though mine seem like they have a solid coat. They smell sour. Don't expire til 2027. I'm really not too concerned with it as the seal wasn't broken. They aren't massive but they are a 1 G size so combine about two normal capsules and you get the idea. I would say-- I've been buying this supplement for about 20 years and the price point it is at is the best price point I've seen so far and since this is a GMP certified facility, it means they have higher quality standards but I'm not sure if it is processed at an FDA certified facility or if it is actually tested but maybe if they do a better job clarifying in the description and highlighting this benefit, people don't realize that's why it is pharmaceutical grade and why it is close to As Good As It Gets. Regardless, I have a slight tingling in my stomach post ingestion, empty stomach. However, you only have to take one of these pills per dose and spread out. I only take one every now and then but mostly just as a pre-workout with other amino acids and caffeine to make my own NO/vasodialator mix for bodybuilding or calesthenics. That said, I really hope they keep this product at a low price point because that is what makes this product so good compared to the mid-price and expensive arginine products. If the manufacturer ever reads this, make sure to emphasize more on the benefits of GMP certified and good manufacturing processes. It's ever so important these days that we know it's not from an uncontrolled environment like a basement or a can. Welp, so far no reactions to it. I think this product works very well and would love to see lab tests and levels because I bet they are doing something right! Will buy this again, likely will subscribe if discounts are deeper

Tablets are WAY too big! I recommend finding a capsule form
These tablets are HUGE. While I can feel that this is helping me, I will buy this supplement in a capsule form. The tablets are just too big. I don't normally have that problem, but these get stuck in my throat.

These are as described. They are pretty big, but I guess you'll expect that. Price was reasonable for the amount you get. Hard to know if they make a difference, but as with most supplements you have to take them over a long period of time, and trust the process.
