Tastes Like Cheating (It's Not)
Most protein powders for GLP-1 users taste chalky, overly sweet, or leave that weird aftertaste that makes you dread your daily shake. Not ASP-1.
We've obsessed over every detail, from the velvety whey isolate to the non-GMO allulose that tastes like real sugar (because it basically is, minus the blood sugar spike). The result? A shake that's creamy, satisfying, and actually something you'll look forward to drinking every day.
Our 30-Day Love It Guarantee
When you glow, we glow.
Try ASP-1 for 30 days. If you don't love the way it tastes, how it makes you feel, or the way it fits into your routine, simply return it. Sealed tubs are refundable for 90 days from delivery. Open one, try it, and send back whatever you haven't started. We'll give you a full refund, no questions asked.
We're confident ASP-1 will become your favorite part of the morning. But if it's not the right fit, we've got you covered.
Doctor-Formulated. Rigorously Tested.

We source only pharmaceutical-grade ingredients, like Magtein® (the only magnesium proven to cross the blood-brain barrier) and premium whey isolate (not the cheap concentrate most brands use).
Your body deserves better than guesswork. ASP-1 is built on evidence, not hype.

Real Results, Real People
Your Glow Guardians
ASP-1 is built around five essential protectors that work together to keep you strong, sharp, and glowing while GLP-1s work.
Muscle
Whey protein isolate + Creatine
Delivers ultra-pure protein + creatine per scoop to help preserve lean muscle while you lose fat, so the weight you drop is the right weight.
Brain
Magnesium L-threonate + creatine
Supports focus and mental clarity through the brain fog that can come with rapid weight loss, plus cellular energy for sharper days.
Gut
Probiotic + prebiotic blend
Soothes the digestive side effects GLP-1s can cause (constipation, bloating) and supports healthy gut motility and comfort.
Skin
Hydrolyzed collagen peptides
Supplies the collagen building blocks your skin draws on during fast weight loss, supporting elasticity, firmness, and a healthy glow.
Flavor
Crave-worthy taste
Sweetened with allulose, a naturally sourced sweetener — so it actually tastes good with no artificial aftertaste and nothing chalky to choke down.
The Weight Is Coming Off.
Your Energy Shouldn’t Be.
You’re crushing your weight loss goals, but you’re exhausted. You look and feel tired. You deserve better than feeling like this.
ASP-1™ is your all-in-one nutrition solution: delicious enough to actually crave, complete enough to ditch the supplement cabinet. Get your glow back, stay full for hours, and finally feel the energy your new life deserves.

Formulated By A Doctor Who Saw What Was Missing
“When the body is under stress, it doesn’t need ‘more supplements.’ It needs the right nutrients, in the right forms, at the right doses.
I saw that in surgical recovery, and I see it now with GLP-1 users. ASP-1 was built to support muscle, energy, and real health, not just the number on the scale.”

Frequently Asked Questions
ASP-1 is designed for anyone on a GLP-1 medication who wants to protect their muscle, skin, and energy while losing weight. Whether you're just starting your journey, mid-way through, maintaining your results, or microdosing for longevity, ASP-1 provides the nutritional support your body needs when appetite is suppressed.
Most protein powders are designed for bodybuilders or general wellness. ASP-1 is specifically formulated for GLP-1 users. It's not just protein. It's an all-in-one formula that combines premium whey isolate, hydrolyzed collagen for skin elasticity, Magtein® magnesium for brain health, probiotic for gut support, and creatine for muscle retention.
Plus, it's sweetened with non-GMO allulose, so it won't spike your blood sugar or interfere with your GLP-1 results.
No artificial sweeteners. ASP-1 is primarily sweetened with allulose, a sweetener found naturally in dates. It tastes like sugar but has a low glycemic index and won't spike your blood sugar.
Perfect for GLP-1 users who need to be mindful of insulin response. No sucralose, no aspartame, no sugar alcohols. Just clean, natural sweetness.
Most people say it tastes fantastic, like a velvety milkshake, not a typical protein drink. We have two flavors (Dark Chocolate and Vanilla Bean), both sweetened naturally with allulose for a smooth, delicious taste you'll actually look forward to.
You can always add flavor (like 100% cacao powder, vanilla extract, or other natural flavors) to enhance it and customize it to your liking.
But if you're not satisfied for any reason, we offer a 30-day love-it guarantee.
At first glance, $109.99 might seem like a lot for a protein shake. But here's the math: You're replacing five separate, clinical-grade supplements that would cost you $145+/month if purchased individually - premium whey isolate ($60), hydrolyzed collagen ($30), Magtein® magnesium ($30), probiotics ($10), and creatine ($15).
You're not just saving $35+/month. You're getting pharmaceutical-grade ingredients (like Magtein®, not cheap magnesium oxide) that actually work, plus the time savings of managing one product instead of five subscriptions. When you factor in what your health and appearance are worth during a $1,200+/year GLP-1 journey, spending $80/month (with subscription) to protect your muscle, skin, and energy isn't expensive - it's essential.
ASP-1 isn't just for active GLP-1 users. Many people continue using it during maintenance or even after stopping their medication because they love how it supports their overall wellness, energy, and daily nutrition.
The muscle support, skin health, brain function, and gut benefits are valuable whether you're on a GLP-1 or not. It's a high-quality nutritional foundation for anyone who wants to feel and look their best.
No, it's designed to support it.
GLP-1s can make it hard to eat enough protein, which can lead to muscle loss and low energy. ASP-1 helps you hit key nutrients even with a smaller appetite. And it's sweetened with allulose, not sugar, so it won't spike blood sugar or derail results.
