For getting amino acids to muscle, free-form EAAs absorb faster (peak plasma 15–30 min vs. 60–90 for whey) and at higher bioavailability (~76% vs. ~59%) — because they skip digestion entirely.*

"I'm feeling so much better. I didn't realize how important amino acids were until I started researching — and now I'm taking what I believe is the best way to get amino acids quickly into your bloodstream, as it doesn't have to digest. Thank you so much; you have now become very important in my life."

WHAT YOUR BODY ACTUALLY USES
Your Body Has Never Used a Gram of Protein. It Uses Amino Acids.
Every protein source — whey, yogurt, eggs, steak — has to be broken down into amino acids before your body can do a single thing with it. Amino acids are what actually build and support lean muscle, skin, hair, and more. Whole protein makes you wait hours for that breakdown. Free-form amino acids are already there.
So the protein was never the point. The amino acids were — and you can get those directly.
*These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure or prevent any disease.
WHAT TO EXPECT
Absorption you can time. Muscle support you build.
15–30 minutes — Peak plasma
Amino acids reach their peak in your bloodstream — this is an absorption timing, measured in studies, not a feeling you'll necessarily notice.*
Each serving — Around your training
Take 4 tablets with water before or after a workout to support recovery while the stimulus is fresh.*
Over weeks — Consistency
Lean-muscle support builds with regular daily use alongside training — not from any single dose.*
We won't promise you'll "feel it" on a timer. The 15–30 minutes is how fast it absorbs; the muscle support is what you build over time.
WHAT'S IN IT
All 9 essential amino acids — 4,000 mg, leucine-leading.
Instant Aminos™ Amino Acid Complex Blend — 4,000 mg per 4-tablet serving, in a WHO/FAO-optimized ratio.*
Miss one, and the whole thing stalls.
Building muscle takes all nine essential amino acids present at the same time. Your body can't make them — they have to come from what you take in — and if even one runs short, the whole process stops. It's the same complete set that makes whey work. Instant Aminos just delivers it without the protein to break down.*
Free-form: already in the usable form.
"Free-form" means each amino acid arrives as a single, finished molecule — not bound up in a protein chain your gut has to take apart. Complete and ready to use. That's what makes four small tablets do the work of a full scoop.*
The complete set, in the form your body uses instantly. Nothing missing. Nothing to digest.
HOW IT REACHES YOU
No Digestion. No Waiting. No Bloat.
In your bloodstream in minutes — not hours.
A protein shake takes the long way. Sixty to ninety minutes of breaking chains apart before a single amino acid reaches a muscle — and that breakdown is the heaviness you've learned to expect after every shake. Free-form amino acids skip the whole detour.
Whole Protein
Locked-together chains. Your gut has to take them apart, one bond at a time. 60–90 minutes — and the bloat that comes with it.
Free-Form Aminos
Already single molecules. Nothing to break down, so they pass straight through the gut wall.
The Result
Into your bloodstream in minutes. The complete set of building blocks, ready to use.
Same building blocks. None of the wait.
ALREADY TAKING AMINOS?
Your body can't build with a partial set.
Muscle is built from all nine essential amino acids at once. Miss one, and the work stalls — no matter how much of the others you take. Here's where the usual stand-ins fall short.
BCAAs
3
Only 3 of the 9
Leucine, isoleucine, valine — and nothing else. The other six still have to come from somewhere.
Collagen
0
An incomplete profile
A structural protein that's missing tryptophan and low in the rest — it can't stand in for the complete set.
Complete and free-form. That's the combination nothing else on this list offers.

THE EQUIVALENCE
Four tablets. The muscle work of a 20-gram scoop.†
It sounds too small to work. Here's why it isn't.
Muscle protein synthesis is triggered by essential amino acids — and free-form EAAs are used so efficiently that a small dose can stimulate it comparably to a much larger dose of whey.† Instant Aminos delivers those essential amino acids directly: no protein to break down, no calories to carry, no wait. The small dose that does the big job.
†Equivalence refers to muscle protein synthesis support, not total protein content. Based on research in older women showing a small dose of essential amino acids stimulated muscle protein synthesis comparably to a larger dose of whey protein (Bukhari et al., 2015). Instant Aminos is not a protein source or meal replacement. Individual results vary.

THE FELT EXPERIENCE
Amino acids aren't just for muscle.
They're the raw material behind how you recover, look, and feel.
Every protein source has to break down into amino acids before your body can use them for anything. The complete free-form set gives your body those building blocks directly — ready for the tissues that rebuild, recover, and renew, all day.
Lean Muscle
Built, not bulked.
The complete EAA set gives your body what it uses to build and maintain lean muscle — leucine-led to support synthesis.*
Recovery Support
Less of the day-after drag.
Amino acids are the raw material muscle uses to repair after training — delivered free-form, ready to use.*
Hair, Skin & Nails
The structural stuff.
Keratin and collagen are built from amino acids — the same complete set your body draws on for hair, skin, and nails.*
Daily Energy
Without the heavy shake.
Four tablets, about 20 calories — the amino acids your body uses, without the calorie load of a full protein shake.*
Lean-Body Support
Works with your goals, not against them.
About 20 calories per serving vs. roughly 160 in a typical whey shake — the muscle-support building blocks, minus the calorie cost.*
Easy on the Gut
Nothing to break down.
Free-form means no digestion — so no heaviness, no waiting, none of the bloat that comes with breaking protein apart.*
*These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease. Individual results vary.
HOW TO TAKE IT
Protein support that fits in your pocket.
Four small tablets — whenever your day needs them.
DAILY USE
4 tablets per serving — taken 1 to 3 times daily. One serving covers your baseline; add a second or third around training or between meals to keep amino acids available when your muscles are doing the work.*
WHENEVER IT FITS
No mixing, no cleanup, nothing to refrigerate. Keep a bottle in your bag, your desk, your gym kit. It's protein support that travels — so staying consistent doesn't depend on being near a blender.
WHY THROUGH THE DAY
Muscle protein synthesis isn't a one-time event — your body draws on amino acids around the clock. Spacing servings keeps the complete set available when it's needed, not just once in the morning.*

Hear from our experts
“Muscle protein synthesis is triggered by essential amino acids — not by protein itself, which the body first has to break down into those amino acids. Instant Aminos delivers all nine in free-form: already in the molecular state the body uses, with nothing to digest first. It’s the complete essential amino acid profile, leucine-led, at a clinically meaningful dose printed in full on the label. For supporting muscle protein synthesis, that’s the most direct form the science points to.”

The Science Advisors
Held to a higher standard.
Independent clinicians and scientists review our formulas — not to endorse them, but to challenge them.
- Independent oversight.
Practicing clinicians and researchers review Triquetra formulas against the published evidence — on an ongoing basis, in market, with real-world outcomes informing every cycle.
- Reviewed against the published evidence.
Every dose, every form, every cofactor pairing is checked against the clinical literature. If the science doesn’t support a claim, the claim doesn’t ship.
- A complete, honestly dosed amino profile.
The advisors signed off on a 4,000 mg dose of all nine essential amino acids in free-form, leucine-leading ratio — the full, label-disclosed amount, never tucked inside a proprietary blend, so what the research uses is what’s in the bottle.*
Advisors are compensated for their time and expertise, never for endorsement.
Frequently Asked Questions
Are EAAs better than whey?
How is this different from BCAAs?
BCAAs are only 3 of the 9 essential amino acids — they start muscle protein synthesis but can't sustain it. Instant Aminos has all 9, in a leucine-leading ratio.*
Will it upset my stomach or make me bloated?
Free-form amino acids are already broken down, so there's no protein to digest and ferment — which is what causes the bloat from many protein shakes.*
When will I feel it?
The 15–30 minutes is how fast it absorbs, not a guaranteed feeling. Lean-muscle support builds with consistent daily use alongside training.*
How do I take it?
Four tablets with 8 oz or more of water, 1 to 3 times daily — on an empty stomach or with food.*
