Ingredients

Four essential protectors working together to keep you strong, energized, and glowing with one delicious scoop for your GLP-1 journey.

Muscle

The Protector
We chose premium ingredients to help you preserve lean muscle while GLP-1s work.
  • Whey Protein Isolate supports muscle maintenance and helps prevent sarcopenia during rapid weight loss.
  • Creatine Monohydrate enhances strength and supports lean muscle retention.

Brain

The Focus Keeper
We selected cognitive-supporting ingredients to combat brain fog and keep you sharp.
  • Magtein® Magnesium L-Threonate crosses the blood-brain barrier to support mental clarity, calm, and focus.
  • Creatine Monohydrate fuels cognitive function and helps maintain mental energy.
  • Methylated B-12 helps maintain your mood and mental sharpness even when calorie intake is low.

Gut

The Comfort Provider
We included gut-supporting ingredients to ease the digestive side effects GLP-1s can bring.
  • Spore-Forming Probiotic helps balance your microbiome and supports the gut-brain-skin axes.
  • Prebiotic Fiber Blend gently feeds beneficial bacteria without the “gas bombs” of cheaper supplements and helps prevent the constipation many GLP-1 users experience.

Skin

The Glow Protector
We formulated with skin-supporting nutrients to help you avoid the gaunt look.
  • Hydrolyzed Collagen Peptides support skin elasticity and help prevent sagging as you lose weight.
  • Zinc & Methylated B-12 supports skin elasticity and cellular repair for a glowing, vibrant appearance.

Flavor

Nourishment made delicious
Dark Chocolate or Vanilla Bean. One scoop, once a day, in water or whatever you already drink.
  • Non-GMO allulose, a rare sugar that occurs naturally in figs and dates, tastes like sugar without the glycemic spike. Low-calorie sweetness made for GLP-1 users.
  • Natural Flavors deliver a velvety-smooth taste you'll actually crave.
  • Premium Texture means no chalky aftertaste. Just a shake you want to drink.

What Customers Say

Is This For You?

Four points in a GLP-1 journey. ASP-1 does something different at each one.

Taken daily

It only works if you take it

Creatine needs daily saturation to do anything. The probiotic has to colonise. Protein and collagen work through steady supply, not the occasional scoop. ASP-1 was formulated to be taken every day, which is why most customers set it to arrive automatically — and why a subscription costs less per tub than buying one at a time.

Made in USA

Proudly manufactured in the United States

Third-Party Tested

Every batch of ASP-1 is verified by an independent laboratory before it ships — not once per formula, but per batch, so the testing matches the tub in your hand.

We verify potency and purity: that each active ingredient is present at the amount printed on the label, and that the powder is clean.

This is separate from how the product is manufactured. Testing checks the finished batch; cGMP governs the process that made it. Both matter, which is why we do both.

cGMP Certified Facility

ASP-1 is manufactured in a cGMP-certified facility.

cGMP — Current Good Manufacturing Practice — is the FDA's standard for how a supplement is actually made: documented procedures, controlled and traceable raw materials, sanitation requirements, and record-keeping that allows any batch to be traced end to end.

It governs the process rather than the formula, which is why it sits alongside third-party batch testing rather than replacing it.

Use Your HSA or FSA

Supplements are not HSA/FSA eligible by default. They become eligible when a clinician documents that you are using them to treat a specific condition. That document is a Letter of Medical Necessity — not a prescription.

Our checkout partner Flex handles it inside the checkout flow: a short health questionnaire, about three minutes. No appointment, and nothing to arrange in advance.

Eligibility is determined at checkout and isn't guaranteed, and we can't give tax advice — your plan administrator can tell you exactly what your account covers.

Checkout With Your HSA/FSA
Maximize your pre-tax HSA/FSA dollars.
  1. 1 Select "Pay another way" or checkout as a guest.
  2. 2 Select the "Flex - Pay with HSA/FSA" option.
  3. 3 Confirm your eligibility.
  4. 4 Enter your HSA/FSA card details.
HSA / FSA

FSA dollars don't roll over

Most FSA plans require your funds to be spent within the plan year, and most reset on 31 December. If you have a balance sitting there, a 90-day supply is the simplest way to put it to work: one Letter of Medical Necessity, one checkout, three months covered.

Eligibility is determined at checkout and isn't guaranteed. Plan rules vary — some employers offer a grace period or a limited carryover, others don't. Check with your plan administrator. We can't give tax advice.
