Contact Pepti about GLP-1 raw material
Two channels, both answered by the same team in Guangzhou. The fastest route is the WhatsApp button, which opens a chat with the Pepti Supply account pre-tagged as an RFQ from this site; email works just as well for buyers who need a written trail from the first message.
What to put in an RFQ
Six lines are enough; the reply is faster and more precise when they are all there.
- Compound — one of Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, Mazdutide, Survodutide, or a custom sequence (attach the sequence and specification).
- Format — raw powder (from 5 g, shipped cold-chain) or lyophilized vials (1 kit = 10 vials), and for vials the strength per vial.
- Quantity — in grams for powder or in kits for vials; a first order is normally 1 kit (10 vials).
- Label — neutral (default) or private label (OEM from 50 kits (500 vials); attach artwork or say it is to come).
- Destination — country and city, and whether the consignee is a research organization, laboratory or company.
- Documents — the batch certificate is included; say if you also need the chromatogram and spectrum, a water or counter-ion result, or a designated-laboratory sample before confirmation.
A template you can paste
Pepti-RFQ [peptiglp1]
Compound: Tirzepatide
Format: lyophilized vials, 10 mg
Quantity: 1 kit (10 vials)
Label: neutral
Destination: (country, city), research laboratory
Documents: batch COA + chromatogram and spectrum
Intended use: research use only
The WhatsApp button pre-fills the first line so the message is routed as an RFQ from this site. On email, put the compound name in the subject line.
What happens after you send it
Review, certificate, quote, confirmation, dispatch photo.
- Eligibility and destination review. Mike confirms that the consignee is a research organization, laboratory or B2B buyer and that the destination and intended use fit the research-use boundary. This happens before any pricing.
- Lot certificate. For a listed compound, the reply names the lot that would ship and attaches its certificate (HPLC purity, MS identity, three dates). For survodutide, which has no public record yet, the certificate comes at this step so you can check it before paying.
- Quote. Unit pricing, the lead-time window from the ladder (sample kits 5–10 days; production batch 14–21 days; oem repeat order 21–28 days, typically), packing and courier basis, and documentation scope, in writing.
- Confirmation and payment. Payment details appear only on the written quotation or order confirmation, after the review above. They are never sent inside a chat before that; treat a message that does so as not from Pepti.
- Dispatch. A packing photograph with the lot label and airway bill is sent on request before courier collection; tracking follows when the parcel is scanned.
Everything in the reply is in writing so it can be filed: the lot alias, the certificate, the window from the ladder and the packing basis. If a detail changes later, for example because released stock is allocated to an earlier order and a new batch has to run, the change is sent in writing too, with the new lot alias and its certificate, before anything ships. A buyer never has to reconcile a verbal promise with a document.
Pepti does not promise a response time on this page because it would be the kind of number that cannot be kept for every time zone. Messages are answered in order, in writing, by the same person who will handle the order.
Why the WhatsApp number is not printed here
So that it cannot be lifted onto a clone site.
Clone sites copy whatever is easiest to copy: photographs, lot numbers, and contact details. Printing a phone number on a page makes it trivial to paste onto another site next to someone else's bank account. The Pepti-RFQ button on this site opens the real Pepti Supply chat through a redirect on this domain, so a buyer who starts from peptiglp1.com always reaches Pepti and a buyer who sees the number elsewhere has no way to confirm it came from here. If you are given a number by a third party, do not use it; use the button.
The same logic applies to email. Pepti uses one address, contact@peptioem.com, for this site and for its main domain. A message from a different domain claiming to be Pepti, or a quote that changes the payment details mid-conversation, should be checked here before anything is paid. The verification guide explains how to confirm the whole chain from this page to a shipped carton.
What Pepti will not answer
If your question is about a compound that is not one of the six listed here, say so; the answer may be that it belongs to Pepti's main catalogue on peptioem.com or that it can be made as a custom sequence, and the reply will point you to the right place rather than quoting something this site does not cover.
Questions that are answered, and usually in the first reply: lot availability and lead time, strengths and fills, raw powder quantities, label options and OEM artwork requirements, certificate contents, chromatogram and spectrum requests, independent-testing coordination, packing and cold-chain details, and identifier cross-checks (CAS, formula, PubChem CID).
Questions buyers ask
What is the fastest way to get a quote?
Press the Pepti-RFQ button, paste the six-line template with your compound, format, quantity, label, destination and document needs, and send. The reply contains the lot certificate, the lead-time window and unit pricing in writing.
Can I get a quote without naming my organization?
You can ask about formats, strengths and documents anonymously. A quote with pricing and a lot allocation requires the consignee type and destination, because eligibility and destination rules are reviewed before a quote becomes an order.
Do you accept RFQs for more than one compound?
Yes. List each compound with its format and quantity; each ships with its own lot certificate. Minimums apply per compound and strength.
How do I know a message is really from Pepti?
It arrives in the Pepti Supply WhatsApp chat you opened from this site or from contact@peptioem.com, it never asks for payment before the eligibility review, and any lot it names can be checked in the public library on peptioem.com. Anything else should be verified against this page first.
