But if you’re doing a double take because, well, amino acid pills? Really Mike?
I know, I know—whoever fights monsters, something something, becomes a guy who peddles amino acids.
Humor me for a minute, though.
For as long as I’ve been in the fitness racket, I haven’t used, recommended, or sold branched-chain amino acid (BCAA) or essential amino acid (EAA) supplements.
In fact, I’ve explicitly dismissed them as useless and told people to just eat protein instead.
And that’s still mostly right.
Many amino acid supplements are still virtually useless for most of us protein eaters—BCAAs, especially—and no amount of amino pills, powders, or potions will ever beat “eating enough protein.”
But I was wrong about one thing.
A correctly dosed EAA supplement does one useful thing exceptionally well:
It rapidly delivers the nine amino acids that stimulate muscle protein synthesis—without requiring a meal or shake.
What changed my mind was a 2023 position stand from the International Society of Sports Nutrition—the first one they'd ever dedicated entirely to essential amino acid supplementation in people who train.
The useful finding wasn't "EAAs are better than whole-food protein." It was more specific, and more interesting:
1. Free-form essential aminos—the kind your body doesn't have to break down first—hit your bloodstream faster than whole protein.
2. Gram for gram, they stimulate more muscle protein synthesis than an equivalent amount of intact protein.
3. You don't need the other 11 amino acids in a normal protein to produce that signal. Just the 9 essentials.
Translation:
When you want to get essential amino acids into your blood, fast and with fewer calories, free-form EAAs are the tits.
That's it. That's the whole pitch.
Practically speaking, then, while EAAs can’t provide protein, deep nutrition, or satiety, they can replace one “job” of a protein powder or snack:
Delivering the amino acids that stimulate muscle protein synthesis.
And that makes them particularly useful in several common scenarios:
1. You want to feed your muscles before or after a workout without something sloshing around in your stomach (especially helpful if you train on an empty stomach).
2. Much of your protein comes from plants, which often provide fewer EAAs per gram and may be lower in leucine, lysine, or methionine.
3. You often have long stretches between meals and want to keep your body’s muscle-building machinery running.
4. You’re dieting hard and want an effective dose of EAAs for roughly 40 calories instead of the 80–100 calories from enough whey to match the aminos.
5. You're traveling and not particularly interested in mixing up shakes in airport or hotel bathrooms.
If any of that resonates with you, then you should pick up a bottle or three of my EAAs here:
And if it doesn’t baste your turkey, then you should promptly delete this email and have a splendiferous day.
So, will my EAAs melt your belly fat into a six pack while you fast?
No.
Are they way more anabolic than whey while somehow containing no calories?
Absolutely not.
But do they give you a fast, portable, precisely dosed source of all 9 essential amino acids when eating or drinking protein isn’t practical?
Yes. Or your money back.

Go for it!

P.S. I almost forgot to mention—don’t buy EAAs for any of the fake reasons invented by sweaty supplement shysters and amplified by ring-light researchers.
Don’t buy them because the amino ratios of protein powder are “off” (they aren’t).
Or because 80% of whey is converted into sugar and then fat in the body (it isn’t).
Or because EAAs can help you lose fat while building muscle (they can’t).
Or because EAAs are “99% utilized” (“trust me bro”).
Or because a handful of EAA pills contains “6x as much protein as whey per serving” (it doesn’t).
Rapidly deliver the nine amino acids that stimulate muscle protein synthesis.
Nothing more and nothing less.
