About
A small supply house for laboratory research material.
MMK Peptides exists to make one thing simple: ordering lyophilized research peptides in sealed vials, at a plainly stated price, without a maze of minimums and hidden fees. We are deliberately small, and every order is read and sent by us.
What we supply
Lyophilized research compounds in sealed glass vials. Retatrutide and Tirzepatide are stocked in 5mg, 10mg, 20mg and 30mg vials, and Klow as an 80mg vial. Not every item comes in every size, so each listing shows only the sizes that item is stocked in, with the price beside each one.
How it is priced
Plainly, and the price changes with the size you pick. Shipping is quoted with your payment instructions so the total is never a surprise at the last step.
Boxes of ten
Boxes of ten are available and priced per box. Our first is ten Retatrutide 20mg vials at $250.00. Ask us for a box price on anything else.
Certificates of analysis
Each product carries its own certificate spot on its page, under the specifications. Where a certificate is attached you can open or download it there. Where it is still being added, the page says so and gives you a number to call so we can send it to you directly.
Who you are buying from
A small supply operation, run by one person who answers the phone. Call or text (682) 239-5132 and you will reach the owner, not a call centre.
Our standard
Straight answers, stated limits.
We tell you what a product is, what it weighs and what it costs. We do not tell you what it will do for a person, because that is not what we sell and not what we are qualified to say.
Our material is supplied for in-vitro laboratory research by qualified professionals. If your intended use is anything else, this is not the supplier for you, and we would rather say that plainly than take the order.
Every order is reviewed by hand before a payment link is sent. That is slower than a checkout button, and it is on purpose: it is how we catch a wrong vial size, a quantity question or a shipping problem before your money moves.
Research use only
Not for human or veterinary use. For laboratory research use only. Not for human or veterinary use, and not for diagnostic or therapeutic use. Nothing on this site is medical advice, a dosing recommendation, or a claim about any human or veterinary outcome. By ordering you confirm you are a qualified researcher purchasing material for laboratory use.
