Lose Fat, Not Muscle on a GLP-1
Lose fat.
Not muscle.
GLP-1 medications work — but when the weight comes off fast, a large share of it can be muscle. Proco is the evidence-first supplement system built to help you protect what matters.
Rapid weight loss doesn't only burn fat. Because a GLP-1 lowers appetite so sharply, protein intake often falls well below what your body needs to hold onto muscle. And muscle is the tissue that keeps your metabolism working and your results lasting — far easier to protect during the loss than to rebuild afterward.
Built on human trials, not hype.
Three levers, each dosed to the ranges used in published research.
Protect your muscle
The single most important nutrient for keeping muscle in a calorie deficit. When appetite is low, a clean shake makes the daily target realistic.
Support strength
One of the most studied compounds in sports science. A daily 3–5g dose supports the resistance training that helps you hold lean mass.
Fill the gaps
Eating less means fewer nutrients overall. Magnesium, omega-3 and vitamin D cover the shortfalls that come with a smaller appetite.
Your routine, made simple.
Quiet credibility. Nothing to hide.
Third-party tested, every batch
Every batch is COA-tested for purity and potency. What's on the label is what's in the tub.
Exact ingredients, exact doses, every claim cited
No proprietary blends hiding under-dosed ingredients. You see precisely what you're taking, and why.
If a human trial doesn't support it, we don't stock it
We don't chase trends. Every product earns its place on the evidence.
Try it for 60 days.
If your first order isn't for you, email us within 60 days and we'll refund it — even if the tub is opened. You don't need to send anything back. That's how confident we are in what's inside.
Keep the muscle.
Keep the results.
