Frequently Asked Questions
What Proco sells
What does Proco sell?
Proco sells evidence-only supplement stacks formulated for weight management, metabolic health, cardiovascular health, and muscle support. Every ingredient is dosed to published human-trial ranges — no proprietary blends, no underdosing. If the human-trial evidence isn't there, we don't stock it.
What is the evidence-only standard?
Every ingredient in every Proco product must have a body of peer-reviewed human clinical trial evidence supporting the dose we use. We rely on randomised controlled trials, systematic reviews, and meta-analyses. When evidence is weak or contested, we say so and don't include the ingredient. The study is cited on every product page.
GLP-1 Support
Why do I lose muscle on a GLP-1?
You eat far less, so protein and key nutrients fall short, and rapid weight loss on low intake draws from lean muscle as well as fat — research shows it can be up to ~40% of the weight lost. The stack helps you protect muscle, heart and metabolic health while you lose.
What's in the GLP-1 Support Stack?
Four evidence-backed essentials:
- Whey Protein — to meet protein targets and support muscle retention
- Creatine — to defend and rebuild lean muscle
- Omega-3 (EPA+DHA) — for cardiovascular and metabolic health
- Magnesium — to cover nutrient gaps that come with eating less
The stack costs $117 — a saving of $25 versus buying each product separately.
How do I take the GLP-1 Support Stack?
A simple daily routine: a protein serving and creatine daily, omega-3 with a meal, and magnesium in the evening. Full usage guidance is on each product page.
Safety and interactions
Are Proco supplements safe?
Every product is dosed to published human-trial ranges, manufactured in GMP/HACCP-certified facilities, and batch-tested with a Certificate of Analysis (COA). The COA is available for every batch on the product page.
Can I take Proco supplements with medication?
If you take any prescription medication or are pregnant, check with your GP or clinician before starting any supplement. Some ingredients have known interactions — for example, omega-3 at high doses with anticoagulants, or magnesium with certain antibiotics. Our product pages flag known clinically significant interactions, but your clinician knows your full medication picture.

Testing and quality
How does COA testing work?
Every batch of every Proco product is independently tested by a third-party laboratory. The Certificate of Analysis (COA) confirms the actual contents and dose of each ingredient in that batch match what's on the label. The COA for each batch is published on the product page.
Do you use proprietary blends?
No. Every ingredient and every dose is listed openly on the label. You always know exactly what you're taking and at what dose.
