GLP-1 category · incretin peptides · research use
GLP-1 peptides — sorted by how many receptors they hit.
The fastest way to navigate the GLP-1 category is receptor coverage: semaglutide engages GLP-1 alone, tirzepatide adds GIP, and retatrutide adds glucagon for triple agonism. Titan supplies these as documented research reagents — lot-matched COAs, HPLC purity targets, crypto checkout. Start with the comparison, then open the compound you need.

The category at a glance
Receptor activity is the line that separates them.
| Compound | Receptor activity | At Titan | |
|---|---|---|---|
| Retatrutide | GLP-1 / GIP / glucagon triple-agonist | 10mg lyophilized vial (in catalog) | Open → |
| Tirzepatide | GLP-1 / GIP dual-agonist | Research reference page | Open → |
| Semaglutide | GLP-1 single receptor agonist | Research reference page | Open → |
Retatrutide is the GLP-1-category compound currently in Titan's catalog. Tirzepatide and semaglutide pages are research reference resources. All are research-use-only; no human-use, dosing, or efficacy claims are made.
One, two, or three receptors
The GLP-1 category is defined by how many incretin pathways a molecule engages. Semaglutide acts at GLP-1 alone; tirzepatide adds GIP; retatrutide adds glucagon for triple agonism. More receptor targets does not mean 'better' — it means a different pharmacology to characterize. The side-by-side comparison lays out where each one sits.
Retatrutide vs tirzepatide vs semaglutide →The lot sheet is the receipt
These are synthesized research reagents, so there is no brand-name authenticity to lean on. Confirm a lot-matched release sheet referenced to the code on the vial before paying — purity by HPLC and identity by mass spec. With crypto there is no chargeback, so that document is what stands in for buyer protection.
How to verify a COA →Reconstitution sets concentration, not dose
Lyophilized GLP-1 peptides ship dry and are reconstituted with bacteriostatic water before in-vitro work. The water volume only sets concentration (mg/mL), not the amount of peptide in the vial. Model any volume against vial size before you draw an aliquot.
Retatrutide reconstitution →Crypto checkout, on-chain proof
Titan is crypto-only (BTC, USDC, SOL). A crypto payment leaves a public, timestamped transaction hash — verifiable proof you sent the exact amount to the address shown. An order ID is recorded with support first, and dispatch follows on-chain confirmation.
