Consistency over the years, great product.
Sometimes things dont need to be hyped up, but these aminos do. Great taste, fast absorption with good results. Great orange flavor. Over 50? Creatine, aminos, whey protein and HMB.

Best Amino Acid Supplement Out There
I've used TW Amino Fuel for well over 10 years. It's a mainstay nutritional product in my arsenal. There are a handful of other liquid amino acid supllements out there that I have used, even another one made by Twin Labs, and none of them are in the same class as AF. It's the best liquid amino I'm aware of, and by extention the best amino acid supplement out there as almost all the others I have used are horse pills. If a person is blending those horse pills into a smoothie, that might make them more bioavailable, but large pills don't dissolve well and are made even led bioavailable by taking four of them. If you go back only a few thousand years in human history you discover that to get the balanced high quality protein in TL AF a person would have not only been lucky and well geographically placed, but also would have had to dedicate their entire day to seeking the nutrition you can now pour into a cup of water in a few seconds. Amino acids in large quantities are not well understood, but it is clear that a body in less than optimal health can make use of a lot more amino acids than nutritionists say is necessary to sustain life. The human digestive tract has a hierarchy of absorbtion, giving precedent to certain nutrients you've eaten. Amino acids are absorbed with the highest priority, and also with the highest efficiency, which is instructive to us in understanding their historical rarity and their value to our bodies. Large quantities of amino acids are useful for all types of healing, for rapid detoxification of the brain, detoxification of the body, strengthening tissue and organs, improving all types of performance: mental physical etc, and can be an effective way to lose weight. I could get up and walk to the fridge and find out if it still does, I'm not sure, but the TL AF bottle used to say right on the bottle that it was not intended to be used for weight loss. Of course it was and is a very effective weight loss product as hunger has maybe three primary components: the stretch sensors in the stomach which give us a sense of being full (which are quite quickly reset after a few weeks of not eating as much), thirst for water (I've read 1/2 of hunger pangs are actually the bodies call for more water, and of course water will also make the belly stretch, addressing the first cause of hunger), and lastly, and most importantly hunger arises from the body sending signals that it's not getting enough nutrition, this last factor one which amino acid supplementation certainly is a key factor in correcting.

WATERED DOWN, Not the same product from years past
I agree with Jennipher's review that the product quality has declined significantly from what I used to purchase, last time about 2013-2014. Before that, I had used it dating all the way back to about the year 2000 or so. It used to have a thick and syrupy consistency, and now it is incredibly watered down! I cannot believe that twin lab would push this kind of substandard product on the market thinking that they can fool those of us who are long time users of this product! Unreal! I'll be returning this.
