For men over 45 who still train hard but keep losing muscle

The Muscle-Only Amino Ratio (Up To 11x More Effective Than Whey) That Finally Gets You Showing Gains Again

Even if you're convinced you're past your prime, and even if every whey and BCAA you've tried quit working years ago.

Still training like you always have. So why does the mirror keep going the wrong way?

You're still up early. Still putting in the sessions. Still grinding the same weights you have for years.

But the reps stopped climbing a while back. And the man in the mirror looks softer than the work deserves.

One real leg day and you limp for three, so a session slips. Then the next one.

You used to complain that you trained six days a week and didn't look like it. Lately you've wondered if this is just what 50 looks like.

You've started skipping the shirt-off photos. Catching a little less of your own reflection.

The effort was never the problem. The rules changed after 45 — once you see exactly what changed, you can train with it instead of against it.

Muscle loss accelerates every decade after 45 — training flattens the slope, it doesn't erase it.

The muscle-loss epidemic almost no man over 45 sees coming

After 45, your body starts shedding muscle every year, whether you train or not.

Left alone, it only speeds up. It has a name most men never hear: sarcopenia. It is why the same training that once built you now barely holds the line.

Here is the part that changes everything. Your muscles did not stop working. They stopped listening. At rest your body runs fine. What changed is the price it charges to turn a workout into muscle. After 45 that price climbs, so the session that used to pay off now barely covers costs.

So let's be straight. If a man is not training at all, that is on him. But if you ARE training, hard, and going backwards anyway, that is not on you. The rules changed and nobody handed you the new ones.

Why more shakes, more scoops, and more BCAAs stopped moving the needle

Whey is not a scam. For everyday nutrition it does a job. The trouble is what happens to it inside a body over 45.

Protein is really just a delivery truck for amino acids, the part that actually builds muscle. But the truck leaks. Your body uses maybe a third of what you pour in. The rest gets flushed away.

So a lot of men switch to BCAAs, and that backfires. BCAAs carry only 3 of the 9 amino acids muscle needs. To finish the job, your body strips the other six out of the muscle you already have. You end up feeding the very problem you are trying to fix.

Pour in protein the body wastes, while the muscle that is left slowly goes. That is the fight almost every man over 45 is losing without knowing why.

Why the ratio is the whole game

Plenty of products list nine amino acids on the label. Almost none get the ratio right, and the ratio is what decides whether those aminos build muscle or just pass through.

Oh!mino's ratio is patented and published. The research sits in The Journal of Nutrition and the NCBI, not on a marketing page.

Every batch is third-party ISO-lab tested, so what the label says is what is in the tub.

That is what separates an amino supplement that reads well from one that actually works.

The Discovery

I spent 30 years making supplements for other brands. Then I built the one I kept for myself.

I'm Michael Maynard. For 30 years I formulated supplements for companies whose names you would recognise. Every formula I made went out under someone else's label.

I'm also a man in his 60s who watched his own strength slide, and a diabetic, so I have spent my life reading what is actually in what we swallow. Most of it, I would not touch.

Then I saw the science on essential amino acids, and on the exact ratio the body uses to build muscle and nothing else. It was the first thing in 30 years I looked at and thought, this one I am keeping.

So I built it for me first. Not to grow hair, not to grow nails, not to fill out a tub. Built for one thing only: muscle. Then I gave it a name. Oh!mino.

How To Get More Muscle After 45

Meet the MSA Complex: all 9 essential amino acids, in the exact ratio muscle is built from

A muscle synthesis activation complex. All 9 essential amino acids in a patented ratio, built for muscle and nothing else.

Third-party labs confirmed up to 99% of it gets used, instead of the roughly one third your body salvages from whey.

Which is why one scoop delivers the essential aminos of over 30 grams of whey. Gram for gram, up to 11x more effective than the protein in your diet, and up to 20x more than BCAAs — findings published in peer-reviewed research, not invented for an ad.

The 9 aminos are not the secret. The exact ratio is, and it is the one thing that will never be printed on the label. Call it the eleven herbs and spices it took 30 years to earn.

Then five electrolytes in proper ratios, not just salt. Adaptogens for recovery. Stimulant-free or caffeinated, your call. Plant-sourced and dairy-free, so none of the whey gas or bloat. Sugar-free.

DAYS 1–7
Recovery comes back
The soreness that used to cost you three days is barely there. You train the next day instead of nursing the last one.
Man loading plates onto the bar
WEEKS 2–4
The numbers start moving
Reps climb. Plates climb. No extra hours in the gym, no cutting the foods you love. The work starts paying off again, the way it used to.
Man confidently looking at his stronger reflection
MONTHS 2–3
The man in the mirror
You catch your reflection and recognise the guy looking back. "Fitter than I've been in twenty years" stops sounding like a stretch.

The athlete you thought you'd lost was never gone. He was waiting for the right fuel.

Straight answers before you decide

Why don't you just print the exact ratio?
Because the ratio is the entire product. We tell you everything else, all nine essential aminos, the electrolytes, the adaptogens, third-party tested for purity. The exact proportions between them stay private for the same reason a recipe stays private: it's the only part that can be copied. Call it the eleven herbs and spices it took 30 years to earn.
Isn't 45+ too late to build real muscle?
No. Researchers at Oklahoma State found middle-aged men build just as much new muscle as college-aged men over eight weeks of resistance training. Age changes the price your body charges for muscle. It doesn't close the account.
What does it actually taste like?
Tropical Splash or Berry, mixed cold. Prefer to skip the shaker altogether? Take it as a capsule instead.
Will this keep me up at night?
Only if you choose the caffeinated version. The stimulant-free formula is our best seller precisely because it works any time of day, including right before bed.
