on every stage.
Peptides and protocols work. But without measurement you're guessing. LoopPep pairs every stage of the wellness journey — GLP-1, gut healing, parasite cleanse, optimized health — with the cheap biomarker tests that prove it worked. Test before. Run the stage. Retest after. That's the loop.

The LoopPep method
Same loop. Every stage.
Whether you're on a GLP-1, cleaning up your gut, running a parasite cleanse, or optimizing for the long haul — the method doesn't change. Bracket every protocol with the right biomarker tests. Compare. Adjust. That's the closed loop.
Test BEFORE
Order the stage's biomarker panel. This is your reference point.
Run the stage
Take the peptide, do the protocol, follow the schedule. The actual work.
Test AFTER
Same panel. Compare side by side. Let AI explain what moved. Adjust. Retest.

Why we measure
Every stage is built around testing before and after. Here's why.
of GLP-1 weight loss can be lean muscle
Without protein optimization and tracking, you lose what you don't want to lose.
develop nutritional deficiencies in 6 months
Eating less means eating denser. Vitamin D, iron, B12, magnesium — these matter.
is what a full panel costs DTC
Hospitals charge $500-1,000+ for the same tests. We show you where to skip the markup.
