What is — Tirzepatide
Tirzepatide is a synthetic dual GIP/GLP-1 receptor agonist peptide, supplied by Peptworks as a lyophilised 10 mg vial for laboratory research use only (RUO). It is a single-chain, fatty-acid-modified peptide engineered to engage both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. Every batch is manufactured to >=98% HPLC purity and ships from EU-based stock with an independent per-batch Certificate of Analysis. It is not a medicine, supplement, cosmetic, food or medical device, and is not intended for human or animal consumption.
Tirzepatide acts as an agonist at two incretin receptors simultaneously, GIP and GLP-1, both G-protein-coupled receptors central to incretin signalling. In research models this dual activation is studied for its effects on cyclic-AMP signalling, insulin-secretion pathways and downstream metabolic cascades. A fatty-acid moiety promotes albumin binding, which in pharmacokinetic research is associated with an extended circulating half-life. All mechanistic characterisation described here refers strictly to in-vitro assays and animal models, not to any human or clinical use.
Research
- Incretin receptor pharmacology (GIP and GLP-1)
- Preclinical glucose and energy-metabolism models
- Dual-agonist signalling and receptor cross-talk
- Receptor binding, selectivity and potency assays
- Peptide pharmacokinetics and half-life studies
- Analytical method development (HPLC / mass spectrometry)
- Lyophilisation, formulation and stability research
Advantages
- In rodent models, used to study changes in food intake and body-weight regulation
- Serves as a reference dual agonist for comparing GIP versus GLP-1 receptor activation in cell-based assays
- Investigated in preclinical models of glucose homeostasis and insulin secretion
- Functions as an analytical reference standard for HPLC/MS method development and purity benchmarking
- Applied in stability and formulation studies of lyophilised peptides
Safety
- Gastrointestinal effects such as reduced food intake and altered GI motility reported in animal studies
- Transient body-weight changes observed in preclinical models
- Handling and injection-site artefacts noted in laboratory animal protocols
- Note: characterised only in research models; not an account of human effects
Ideal for
- In-vitro receptor pharmacology and binding assays
- Preclinical metabolic and energy-homeostasis studies
- Comparative incretin (GIP vs GLP-1) signalling research
- Analytical reference standard for HPLC / MS workflows
- Peptide formulation, lyophilisation and stability research

Frequently asked questions
Where can I buy Tirzepatide in bulk in the EU?
Peptworks supplies Tirzepatide (GLP-1/GIP) 10 mg vials wholesale from stock already located inside the EU, with intra-community shipping in 3-5 business days and no customs. It is a B2B research-reagent supplier (Research Use Only) offering bulk unbranded vials or white-label. Orders start from a 4-vial pack per reference.
What is the wholesale price per vial for Tirzepatide?
Tirzepatide 10mg has two public per-vial prices: €39.90 in a 4-vial pack and €25.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Tirzepatide vs retatrutide: what is the difference?
Tirzepatide acts on two receptors (GIP and GLP-1) and is an approved medicine (Mounjaro, Zepbound); retatrutide adds a third target, the glucagon receptor, and is still investigational (Phase 3). See our guide "Retatrutide vs tirzepatide" for a side-by-side comparison.
Do you offer Tirzepatide as white-label?
Yes, in the white-label sense: Tirzepatide comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for Tirzepatide?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy metals. The QR code on the box links to that specific batch's CoA and can be verified through Peptworks.
How do I pay and how fast does it ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site. Orders ship from EU-based stock within 3-5 business days intra-community, with no customs for EU destinations. The site is available in 10 languages.
