the honest scoop

Real protein. Real aminos. Nothing sprinkled on top.

Real whey isolate already delivers the aminos that drive recovery — so that's all we give you, and we refuse to spike the label with cheap free-form aminos to fake a bigger number.

Recovery is where the growth actually happens.

Post isn't a workout or a meal plan — it's the recovery layer underneath them. Train hard and the result is decided by how well you bounce back. Fall short on protein and you leak muscle, strength, and progress. A generous dose of clean protein is the simplest fix.

The day after legs

Stairs aren't a death sentence. You walk into the next session instead of limping past it.

Two-a-days

Back-to-back sessions stop compounding into a hole you can't climb out of.

In a cut

Eating less but training hard — a big, clean 25g protein hit helps you hold the muscle you earned without the extra calories.

The loop

Recover well, train again, progress. Skip recovery and the whole thing stalls — and that's where the results actually live.

Post supports recovery with 25g of complete protein — and the BCAAs and leucine that come naturally with it.

what it actually does

The protein is the formula.

Whey isolate already contains the BCAAs and leucine that signal repair. At 25g you get roughly 5.5g of BCAAs and 2.7g of leucine — naturally, no spiking. Real complete protein brings the aminos that matter. That's the whole mechanism.

Cheap proteins pad their numbers with free-form aminos so the label looks bigger than the actual protein. We don't. Every gram is complete protein, printed on the front, third-party tested.

Straight answers.

The questions people ask about protein — and the ones a good coach knows you should. No spin.

Pre-order Post

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

When should I take it?

Right after you train is ideal, but your total daily protein matters most. A scoop post-session is the simplest way to hit the recovery window and your daily target at once.

Is the leucine added, or natural?

Natural. We don't spike the label with free-form aminos. The ~5.5g of BCAAs and ~2.7g of leucine come from the 25g of whey itself — real complete protein, not aminos sprinkled on top to fake a bigger number.

Why no HMB or added aminos?

Because a clean 25g of complete protein already delivers the leucine that drives recovery — adding more is paying for redundancy. Substrate is about nailing the fundamentals, not stacking shiny extras onto the label.

Why does protein matter so much for recovery?

Training breaks muscle down; protein is what rebuilds it. Fall short on daily protein and you lose muscle, strength, and recovery — soreness lingers and progress stalls. A clean 25g scoop after training is the simplest way to hit the recovery window and your daily target at once.

Isolate vs concentrate — why isolate?

Isolate is filtered further: more protein per gram, and very low lactose and fat. We use grass-fed isolate so the scoop is almost pure protein and sits easy on the stomach — even if you're a little dairy-sensitive.

Is it amino-spiked?

Never. Some brands add cheap free-form aminos so the protein number looks bigger than the real complete protein. Every gram on our label is complete protein.

Does it have lactose? Is it gluten-free?

Grass-fed isolate is very low in lactose and naturally gluten-free. Most people who don't tolerate cheap concentrate do great with it.

What's the deal with the Pre bundle?

Pre and Post are the training duo — energy in, recovery after. Buy both and save 10%, and another 10% when you subscribe. Fundamentals, bundled, at the price they should be.

When does Post ship?

Post is on pre-order while we finish the first production run. Reserve yours now and you're first in line when it lands — and the 90-day guarantee still applies.

Can I cancel anytime?

Yes. Skip, pause, or cancel from your account whenever you want, no hoops. And there's a 90-day money-back guarantee if it's not for you.
