AP2-T
A dual GIP/GLP-1 receptor agonist widely studied for metabolic research. Lyophilized (freeze-dried) form, verified 98%+ purity. Available in 15mg and 30mg vials.
What Is AP2-T?
AP2-T is research-grade tirzepatide — a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Originally developed as an investigational compound for metabolic research, tirzepatide has become one of the most widely studied peptides in clinical settings. Published research in The New England Journal of Medicine and The Lancet has documented its effects on glycemic control, body composition, and metabolic biomarkers.
History
Tirzepatide was developed by Eli Lilly and Company, with the first clinical trial results published in 2018. The compound received regulatory approval in 2022 under the brand name Mounjaro for a specific clinical application, followed by additional approval as Zepbound in 2023. The SURPASS and SURMOUNT clinical trial programs generated extensive published data on tirzepatide's dual-incretin mechanism. It remains one of the most actively investigated compounds in metabolic research.

Certificate of Analysis (COA)
Every batch of our peptides is independently tested by third-party laboratories to verify purity, identity, and potency. We maintain 98%+ purity standards across our entire product catalog.
Reconstitution & Storage
Reconstitute with bacteriostatic water (BAC water). Using a sterile syringe, slowly inject 1-2mL of BAC water into the vial, directing the stream against the glass wall. Do not inject directly onto the lyophilized powder. Gently swirl until fully dissolved. Do not shake.
Store unreconstituted vials at room temperature away from direct sunlight. After reconstitution, store at 2-8°C (standard refrigerator). Use within 30 days of reconstitution. Do not freeze.

Frequently Asked Questions
What is AP2-T?
AP2-T is Protocol Aminos' research-grade tirzepatide — a synthetic peptide that acts as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Tirzepatide is one of the most widely studied peptides in metabolic research, with extensive clinical trial data published in The New England Journal of Medicine and The Lancet.
How does AP2-T work?
Tirzepatide activates both GIP and GLP-1 receptors simultaneously, engaging two incretin pathways involved in glucose regulation, insulin secretion, and appetite signaling. This dual-agonist mechanism has been studied for producing greater metabolic effects than single-receptor compounds in published clinical research.
Is tirzepatide a GLP-1?
Tirzepatide is not a pure GLP-1 receptor agonist. It is a dual GIP/GLP-1 receptor agonist, meaning it activates both GIP and GLP-1 receptors. This dual mechanism distinguishes it from single-target GLP-1 agonists and is a key area of ongoing research.
What is the difference between semaglutide and tirzepatide?
Semaglutide is a GLP-1 receptor agonist (single target). Tirzepatide is a dual GIP/GLP-1 receptor agonist (two targets). Published head-to-head data from the SURPASS-2 trial (Frias et al., 2021, NEJM) compared the two compounds directly. Protocol Aminos carries AP2-T (tirzepatide) in 15mg and 30mg lyophilized vials for research use.
Does tirzepatide work?
Multiple Phase 3 clinical trials have documented tirzepatide's effects on metabolic parameters. The SURPASS and SURMOUNT trial programs, published in peer-reviewed journals, report significant effects on glycemic control and body composition. These are research findings and do not constitute medical advice.
What is compounded tirzepatide?
Compounded tirzepatide refers to tirzepatide produced by compounding facilities rather than the original brand manufacturer. AP2-T is Protocol Aminos' research-grade tirzepatide, lyophilized and third-party tested at 98%+ purity with a batch-specific Certificate of Analysis.
How much is AP2-T?
AP2-T is offered in two size options: 15mg for $129 and 30mg for $199. Both ship in lyophilized (freeze-dried) form with a batch-specific COA. Free shipping on orders over $150.
Does the product come with instructions?
Each order includes product documentation with storage requirements, reconstitution guidelines, and handling instructions. For research guidance, visit our blog at /blog.
What's the actual amount in each vial?
Each vial contains the labeled amount of tirzepatide in lyophilized form. The exact quantity is verified via third-party testing and documented on the batch-specific Certificate of Analysis.
Are additional supplies needed?
Yes. AP2-T ships lyophilized (freeze-dried) and must be reconstituted with bacteriostatic water prior to use. Bacteriostatic water and syringes are not included and must be sourced separately from a verified research supplier.
How long does a vial last?
Unreconstituted lyophilized AP2-T has a long shelf life when stored in a cool, dry place away from direct light. Once reconstituted, store refrigerated at 2–8°C and use within the standard research window. Specific stability data is available on request.
