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.

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 in a single order.

Your Glow Guardians
ASP-1 is built around four essential pillars — muscle, brain, gut and skin — working together to keep you strong, sharp and glowing while GLP-1s work. And it's crave-worthy enough that you'll actually want it every day.
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.

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.

What GLP-1 users say about ASP-1
4.9 out of 5 · 314 reviews
A selection of verified-buyer reviews, quoted in full and unedited.
ASP‑1 Protein is one of the few supplements designed specifically with GLP‑1 users in mind, and it shows. As someone navigating appetite changes, slower digestion, and the need for higher-quality nutrition while on GLP‑1 therapy, this protein formula fills a gap that traditional whey or plant proteins don’t always address. Gentle on the stomach: GLP‑1 medications can make heavy or foamy proteins hard to tolerate. ASP‑1 mixes smoothly, sits light, and doesn’t cause the bloating or nausea that some powders trigger. High-quality protein blend: The formula prioritizes easily absorbed protein, helping support muscle maintenance during periods of reduced appetite. Flavor & texture: Surprisingly clean taste, not overly sweet, and blends well with water or almond milk. Texture is thin rather than chalky, which is perfect for GLP‑1 users who prefer lighter consistency. ASP‑1 Protein is an excellent choice for anyone on GLP‑1 therapy who needs a protein supplement that’s gentle, effective, and tailored to their nutritional needs. If you struggle with traditional protein powders or want something formulated with GLP‑1 side effects in mind, this is a standout option.
I’ve been on a GLP-1 medication for a few months, and getting enough protein has definitely been a challenge. I’ve tried several protein powders, and Habthera ASP-1 is one of the few that I actually enjoy drinking.
The flavor is great, it mixes easily, and it doesn’t have that chalky texture that many protein powders do. I like that it’s designed specifically for GLP-1 users, so it feels like more than just a basic protein shake.
It’s become an easy way for me to stay on top of my protein intake on days when I’m not very hungry. Overall, I’m really happy with it and plan to keep using it.
I have only taken Habthera for a few days but I love it and start each morning with a shake..it makes me feel centered..I don’t have the need for coffee. I hope that it has a good effect on my skin as I am a GLP1 user and have lost weight in my lower face. Here’s hoping!
Great Flavor. Just blend with water for about a minute and drink away! Not too sweet, just right.
I’ve never used a protein drink before, so I have nothing to compare to.
The only issue was I didn’t see any instructions, but it came with a scoop and I had a mini blender, so I just went for it. Delicious.
Before I’d even found ASP-1, my trainer mentioned I should look for a protein and micronutrient combo product specifically for GLP-1 users. Found this shortly after and it matched everything she described.
I bought this for the protein and muscle support angle, but the mental clarity improvement caught me off guard. I read recipes correctly now instead of having to read them three times.
My appetite is almost nonexistent these days, so getting enough protein has been difficult. This has become the easiest part of my nutrition plan.
I have not started my GLP-1 yet, but have started using the ASP-1 protein powder. I add mangos, bananas, some collagen with coconut water, and it is great meal replacement.
Since starting my weight loss medication, eating enough has been difficult. This helps fill the gap without making me feel overly full.
This protein powder tastes great and has been an important source of nutrition On my GLP-1 journey.
The disappointment the GLP1 has caused I’m thankful to have the opportunity to add a shake that actually works.
