View brandDetailed compound information
Retatrutide is a synthetic peptide agonist at three receptors simultaneously: GIP (glucose-dependent insulinotropic polypeptide), GLP-1 (glucagon-like peptide-1), and glucagon receptors. Research models demonstrate substantial reductions in body weight and glycemic parameters in obesity and type-2 diabetes investigations, exceeding the effects of dual GIP/GLP-1 agonists. The glucagon component is thought to contribute additional hepatic and energy-expenditure effects.

Nothing dramatic to report — I ordered, it arrived quickly, the product is exactly what the listing said it would be. About three weeks in and I am seeing what I was hoping for. This is my new go-to supplier.
Rien de spectaculaire à raconter — j'ai commandé, c'est arrivé vite, et le produit est exactement ce que la fiche annonçait. Trois semaines plus tard et je vois ce que j'espérais. C'est mon nouveau fournisseur attitré.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 5mg vial with 2mL bacteriostatic water → 2.5 mg/mL. On a U-100 insulin syringe, 8 IU = 0.08 mL = 200 mcg as a starter dose per research protocols.
Tried a few different vendors over the past year and the difference is obvious. The certificate matches the batch, the vial looks right, and you can tell it is the real product. Shipping was a bit slower than the cheap places but absolutely worth waiting for.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
