Questions

Frequently asked.

What does “research use only” mean here?: The material is supplied as a laboratory reagent for in-vitro research by qualified purchasers. It is not for human or veterinary use, and not for diagnostic or therapeutic use. The label, the order emails and the checkout all say so, and we act on it: orders or messages that indicate a prohibited use are cancelled.
Who may purchase?: Qualified purchasers aged 21 or over acting on behalf of a research organization or in a bona fide research capacity. We ask for your organization, role and research area when you create an account. Orders from accounts we have not yet approved are reviewed by a person before any payment is requested, and we may ask for documentation. We do not sell to clinics, medical spas, wellness or aesthetic practices, prescribers, pharmacies, coaches or trainers.
What is in the vial?: Retatrutide (LY3437943), CAS 2381089-83-2, as a lyophilized powder, net content 10 mg per vial. Counter-ion and measured net content are stated on each lot's record.
How is each lot tested?: An independent laboratory tests every lot before it is released for sale: identity by LC-MS, purity by HPLC, net peptide content by quantitative HPLC and bacterial endotoxin by LAL. A lot cannot be offered on this site until those results and the laboratory's report are on its lot record.
How do I check a certificate of analysis?: Each lot record names the testing laboratory and, where the laboratory offers one, its verification link and key. Use them at the laboratory's own site to confirm the report matches what we publish. Our lab-testing page explains each test and what a certificate does and does not show.
How should the material be stored?: Lyophilized, at −20 °C for long-term storage or 2–8 °C short-term, protected from light and moisture. Allow the vial to reach room temperature before opening. Each lot's retest date is on its record.
Do you provide protocols, reconstitution or dosing information?: No. We do not provide protocols, reconstitution, administration or dosing information, and we do not answer questions about use in humans or animals. We are glad to help with storage, documentation and COA verification.
Do you sell solvents, diluents or supplies?: No. We do not sell solvents, diluents or injection supplies, and we do not link to sellers of them.
Where do you ship, and how fast?: United States addresses only. We do not ship internationally. Orders with payment confirmed before 2:00 pm ET, Monday–Friday, ship the same business day. Others ship the next business day. Lyophilized material ships at ambient temperature in protective packaging. From June through September we pack orders in an insulated mailer. Orders of $300 or more require an adult signature on delivery.
What is your returns policy?: All sales are final. Because storage cannot be verified once material leaves our control, we do not accept returns, and opened vials cannot be returned. If an item arrives damaged or is not what you ordered, contact us within 72 hours of delivery with your order number and photos of the packaging, the label and the damage. We replace the item or refund it, at our choice.
How do I pay?: By bitcoin, priced in US dollars. Your order page opens the payment screen, which shows the address and the exact amount in bitcoin, held for 30 minutes. Bitcoin payments cannot be reversed once sent, and we confirm each payment on the blockchain before the order ships. Payment is made only to the Bitcoin address shown at checkout on this site. We never ask for payment to another address or by another method.
What happens if a lot fails testing?: A lot that does not meet specification is not released for sale, and its record stays on our lab-testing page marked as failed. If a later test changes a published result, the lot record is updated, the change is listed in the corrections log on that page, and we email everyone who bought that lot.
Do you supply institutions?: Yes. Contact us before ordering so we can verify your organization and confirm availability. Payment is made at checkout on this site.
Is Recon Labs affiliated with Eli Lilly?: No. Recon Labs has no affiliation with Eli Lilly and Company.
