Question 1

Does Titan Peptide Lab sell tirzepatide?

Accepted Answer

No. Titan does not stock tirzepatide. The GLP-1-class research compound Titan supplies is retatrutide (LY3437943), a GLP-1 / GIP / glucagon triple agonist provided as a lyophilized powder for in-vitro laboratory research. We say this plainly rather than redirecting a tirzepatide search to a mislabeled vial — if your protocol specifically requires tirzepatide's dual GLP-1/GIP profile, retatrutide is a different molecule with an added glucagon-receptor component.

Question 2

Where can I buy tirzepatide-class peptides?

Accepted Answer

Buy from a supplier that clearly separates laboratory research use from human use and exposes a lot-matched release sheet, an HPLC purity target, mass-spec identity confirmation, visible shipping terms, and clear checkout. Titan Peptide Lab supplies research-use retatrutide (LY3437943) — a GLP-1 / GIP / glucagon triple agonist — with a lot-matched documentation workflow and crypto-only checkout. It is sold strictly for in-vitro laboratory research, not for human use.

Question 3

What is the difference between tirzepatide and retatrutide?

Accepted Answer

Tirzepatide is a dual agonist active at the GLP-1 and GIP receptors. Retatrutide is an investigational triple agonist active at the GLP-1, GIP, and glucagon receptors. Both appear in incretin-pathway and metabolic-signaling research literature, but the added glucagon activity makes retatrutide a distinct molecule with a broader receptor profile. Titan supplies retatrutide strictly as a research compound and makes no human-use, therapeutic, or efficacy claims about either.

Question 4

Is tirzepatide approved or available for human use?

Accepted Answer

Research-grade tirzepatide sold as a reagent is not approved by the FDA or any regulator for human use and is not a commercial medicine. Titan supplies retatrutide only as a research-use-only reagent for in-vitro laboratory work — not for human or animal consumption, diagnostic, therapeutic, or preventative use.

Question 5

How do I verify the quality of a peptide before buying?

Accepted Answer

Ask for a lot-matched certificate of analysis tied to the code on the vial you will actually receive, not a stock document. It should show an HPLC purity result against a stated target and a mass-spec identity confirmation. Confirm the format (Titan ships lyophilized powder for reconstitution), the vial size on the product page, and the checkout and shipping terms. A source that hides any of these is the one to skip.

Question 6

Is it safe to pay for peptides with crypto before shipping?

Accepted Answer

Crypto payments can't be reversed, so the right screen is the supplier's documentation, not chargeback protection. With Titan an order ID is recorded with support before payment, many new buyers start with a single vial to vet the source, and payment is confirmed on-chain before dispatch. Every order ships with a lot-matched release sheet tied to the lot code on the vial, and unopened items are returnable within 14 days.
