Wholesale Retatrutide pens for research suppliers
Retatrutide is a synthetic peptide studied in laboratory research as an agonist at the GLP-1, GIP and glucagon receptors. Ascension Healthcare supplies retatrutide as pre-filled pens in two strengths, 20mg and 40mg, so research suppliers can stock finished, packaged pens rather than preparing their own from lyophilised powder. Both strengths share the same Swiss manufacture and pen format, which makes it simple to offer a choice of strengths from one wholesale supplier.
Single pens and wholesale pricing
You can buy 1 to 9 Retatrutide pens of each strength online at single-pen prices, delivered in the UK and paid by card or crypto through PayRam. Wholesale Retatrutide orders start at 10 pens per strength. The 20mg and 40mg strengths are quoted separately, so each needs at least 10 pens. Unit pricing falls as quantities rise, and each pen type and strength is priced on its own quantity. Add the quantities you are considering to an enquiry and we will reply with a written quotation covering current pricing, availability, delivery and terms. No payment is taken when you enquire.
Swiss manufacture and batch documentation
Retatrutide pens are manufactured in Switzerland under strict quality control measures. Ask for the certificate of analysis (COA) and batch documentation for the stock you are quoted, and check the batch number on the paperwork against the pens you receive. An independent Janoshik test of a Retatrutide 30mg sample (batch 2315, 15 September 2026) reported 99.845% purity. See the laboratory report. The result applies to the tested sample.

Storage and handling
Follow the storage instructions on the product label and batch paperwork. Confirm transport requirements before you order so someone can receive the parcel and store the pens promptly. Our pen storage and handling guide has more detail.

Retatrutide pen wholesale questions
Can I buy a single Retatrutide pen?
Yes. Choose “Single pens” above to buy 1 to 9 pens of each strength, delivered to a UK address and paid by card (Visa, Mastercard, Apple Pay or Google Pay) or crypto through PayRam. For 10 or more pens of one strength, or delivery to the EU or US, send a wholesale enquiry.
What is the minimum wholesale order for Retatrutide pens?
10 pens per strength. There is no fixed maximum; tell us the quantities you have in mind and we will confirm availability.
Can I combine Retatrutide with other pens in one enquiry?
Yes. One enquiry can include any pens in the wholesale range. Each pen type and strength is priced on its own quantity, so quantities are not pooled across products.
Is the Retatrutide pen for human use?
No. Retatrutide pens are supplied to businesses for lawful laboratory research only and are not for human or veterinary use. See our research use policy.
