GLP Peptides — Semaglutide, Tirzepatide, Retatrutide research analogs
The complete GLP peptide family in one collection. Three generations of receptor agonists at ≥99% purity, third-party COA per lot, same-day ship from Manhattan, NY.
The three GLP generations
GLP1-S
Semaglutide research analog. Long-acting GLP-1 receptor agonist studied for ~16% peak weight loss and strong cardiovascular endpoint reduction.
- Peak weight loss
- ~15.6%
- Price
- $45.00
GLP2-T
Tirzepatide research analog. Adds GIP receptor agonism on top of GLP-1 — 30–50% greater weight loss than semaglutide at comparable dosing.
- Peak weight loss
- ~20.9%
- Price
- $50.00
GLP3-R
Retatrutide research analog. Adds glucagon on top of the tirzepatide dual mechanism — the highest weight-loss numbers ever recorded in an obesity trial.
- Peak weight loss
- ~28.7%
- Price
- $85.00
Why researchers buy GLP peptides from BioInfinity Lab
The GLP peptide class is the most-scrutinized research area of the decade. Sourcing quality analogs matters — impure or mislabeled material invalidates months of data. Every GLP peptide we ship carries third-party HPLC + mass-spec verification with a lot-matched Certificate of Analysis printed inside the box.
≥99% HPLC purity
Every lot HPLC + mass-spec verified. Purity below spec is rejected before packaging.
Independent COA per lot
Third-party lab COA printed in the box and mirrored on our public COA Library.
