Tirzepatide 30mg (10 Vials / Kit)

Tirzepatide at a glance

Tirzepatide, developed under the code LY3298176, is a synthetic 39-residue peptide whose backbone is modeled on glucose-dependent insulinotropic polypeptide, with substitutions that also give it activity at the GLP-1 receptor. A fatty diacid side chain attached through a linker lets the molecule bind serum albumin, which slows its clearance. Its molecular formula is C225H348N48O68, with a molecular weight of roughly 4813.5 g/mol, and listings here supply it as a freeze-dried powder for laboratory work.

Price and availability

Sold by BioPepta and sent from China, this listing is a kit of 10 vials at 30mg each (300 mg in total). At $125.00 for the kit, that works out to $0.417 per mg. Across 22 brands listing Tirzepatide here, the middle half of prices falls between $0.475 and $1.00 per mg; this kit is below the typical range, so among the cheaper options. Checkout goes into escrow first; the funds move to BioPepta once delivery is confirmed.

What it is studied for

Researchers describe tirzepatide as an imbalanced dual agonist: in published receptor assays it shows comparatively strong GIP-receptor activity alongside more modest GLP-1-receptor engagement. Both targets are class B G protein-coupled receptors that signal largely through cAMP. In metabolic models, this combined input is studied for glucose-dependent insulin release from pancreatic beta cells, reduced glucagon output, delayed stomach emptying and central effects on appetite circuits. Whether GIP-receptor activity contributes something distinct, for example in fat tissue, or partly acts through receptor desensitization remains an open and actively debated question in the literature.

Research and regulatory status

Few compounds sold as research peptides have a clinical record this extensive. A large late-stage trial program supported regulatory approvals for type 2 diabetes and, later, for chronic weight management, and further studies have examined obstructive sleep apnea, fatty liver disease, heart failure and cardiovascular outcomes. That record belongs to the pharmaceutical product, however. Vials listed on GLP1 Forum Escrow are research-grade material for laboratory study, and their quality depends on the individual brand, which is why third-party test reports matter.

Checking the lab data

A credible report should show a mass-spectrometry result consistent with the expected mass of about 4813.5 Da; the lipidated side chain makes truncated or incompletely modified material comparatively easy to spot. HPLC purity should be stated as a percentage with the chromatogram attached, not just a pass mark. Look for measured peptide content per vial compared with the label claim, plus a uniform white lyophilized cake and a batch number and test date that match the vial.

An independent lab report is attached to this listing, and the panel above shows the measured result next to the labelled amount.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 30 mg vial dissolved in 2 mL gives 15 mg/mL, or 30 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
