What is — Retatrutide
Retatrutide is a synthetic triple-agonist research peptide that targets the GLP-1, GIP and glucagon (GCG) receptors. Peptworks supplies it as a lyophilized (freeze-dried) 10 mg vial for laboratory research use only, in bulk unbranded format (white-label). It is not a medicine, supplement, cosmetic or medical device, and is not for human or animal consumption. Every batch ships with an independent Certificate of Analysis confirming >=98% HPLC purity and heavy-metals testing, accessible via a unique QR on the box.
As studied in preclinical and in-vitro systems, Retatrutide acts as a single molecule with agonist activity at three incretin and glucagon-family receptors simultaneously: the glucagon-like peptide-1 receptor (GLP-1R), the glucose-dependent insulinotropic polypeptide receptor (GIPR) and the glucagon receptor (GCGR). This combined receptor engagement is the focus of research characterizing downstream signalling, receptor binding affinity and metabolic pathway modulation in cell-based and animal models. Peptworks makes no representation about effects in humans.
Research
- Metabolic and energy-homeostasis research in animal models
- Incretin receptor pharmacology and multi-receptor agonism (GLP-1R / GIPR / GCGR)
- Adipose tissue and lipid-metabolism cell models
- Hepatic lipid and glucose-handling research in preclinical systems
- Receptor binding, selectivity and signalling assays in vitro
- Comparative peptide structure-activity relationship studies
Advantages
- Research-model utility: enables in-vitro and animal studies of simultaneous GLP-1R/GIPR/GCGR agonism from a single reference compound
- High analytical consistency (>=98% HPLC purity) supporting reproducible assay conditions across batches
- Per-batch independent CoA (HPLC + heavy metals) for documented experimental provenance
- Lyophilized format for extended stability and flexible reconstitution in laboratory protocols
- QR-linked batch traceability that resellers can pass through to their own laboratory customers
Safety
- Reported strictly within research literature and preclinical/animal models, not as human outcomes
- Gastrointestinal-related observations (such as changes in food intake and body-weight trajectory) documented in animal metabolic studies
- Dose-dependent metabolic parameter shifts reported in preclinical model systems
- As a research reagent, no human safety profile is claimed or implied; handle under appropriate laboratory controls
Ideal for
- B2B resellers building a GLP-1 / metabolic research-peptide catalogue in the EU
- Resellers who want unbranded vials to sell under their own label
- Laboratories and research suppliers requiring documented per-batch purity
- Distributors wanting in-EU stock with intra-community 3-5 day shipping and no customs
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.

Frequently asked questions
Where can I buy Retatrutide in bulk in the EU?
Peptworks supplies Retatrutide (10 mg lyophilized vials) in bulk from stock already inside the EU, so orders ship intra-community in 3-5 business days with no customs. It is a B2B wholesale and white-label supply only, sold as a Research Use Only reagent, not to end users. Orders start from a 4-vial pack per reference.
Do you ship Retatrutide to the UK?
Yes. We ship to the United Kingdom by express courier, usually in 2–4 business days, with free shipping from €500 (€24.90 below). The UK is outside the EU, so the parcel goes through UK customs: there is no import duty on these vials, but on orders above £135 UK import VAT (20%) and the courier's handling fee are paid by the recipient on delivery.
What is the wholesale price per vial of Retatrutide?
Retatrutide 10mg has two public per-vial prices: €55.90 in a 4-vial pack and €35.00 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. 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. no card is taken on site.
Retatrutide vs tirzepatide: what is the difference?
Tirzepatide is a dual agonist of the GIP and GLP-1 receptors and is an approved medicine (Mounjaro, Zepbound). Retatrutide is an investigational triple agonist that also activates the glucagon receptor (GCGR) and is still in Phase 3 development. Our guide "Retatrutide vs tirzepatide" compares receptor targets, structure and status side by side.
Do you offer Retatrutide as white-label?
Yes, in the white-label sense: Retatrutide 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 Retatrutide?
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?
Each box carries the Peptworks label with a unique QR code. Scanning it opens the independent Certificate of Analysis for that specific batch, including HPLC purity (>=98%) and heavy-metals testing, and the authenticity is verified through Peptworks. This lets your own downstream buyers confirm the batch data directly.
Is Retatrutide from Peptworks intended for human use?
No. All Peptworks material is supplied strictly as a laboratory research reagent, Research Use Only. It is not a medicine, supplement, cosmetic or medical device, and it is not for human or animal consumption. Buyers are B2B resellers and laboratories responsible for compliant handling and onward labelling within their jurisdiction.
