Who does what
Peptide King is an education, marketing and referral hub. The participating suppliers — currently Eon Peptides and My Quality Supply — each set their own eligibility rules, handle their own orders, publish their own product facts and documentation, and run their own fulfilment, shipping and refund policies. Those policies can differ between suppliers and can change.
Partners promoting Peptide King should lead with Peptide King branding and follow each supplier’s current written rules on names, logos and trademarks. Naming a supplier here does not grant permission to use its brand in promotional materials.
Laboratory research use only
Materials offered by the participating suppliers are supplied for laboratory research use only — not for human or veterinary use. Nothing on Peptide King is medical, dosing, administration or treatment guidance, and nothing here describes any health outcome.
COA verification checklist
A certificate of analysis (COA) is a supplier-provided record of specified tests on one lot. Use this checklist each time you review one.
- 1Obtain the current supplier-provided document for the specific compound and the specific batch or lot you are reviewing — not a generic or older example.
- 2Match the product name and the lot or batch identifier on the document to the product record you are looking at. If they do not match, the document does not describe that material.
- 3Review who performed the testing (the named laboratory), the test date, the methods listed, the specific tests reported and the stated scope of those results.
- 4If a record is missing, out of date or mismatched, ask the supplier directly. Do not fill the gap with assumptions.
- 5Never infer safety, efficacy, approval or any test that is not reported from a purity figure. A purity figure answers one narrow question about one lot.
Available is not the same as verified
A document being available tells you a supplier has published a record. It does not by itself confirm the results for the material in front of you — that depends on the document matching the product and lot, and on what it actually reports. Peptide King does not perform testing and does not publish its own results.
Before visiting a supplier
- Be clear on your laboratory research purpose.
- Review the supplier’s own eligibility requirements and terms.
- Check what documentation the supplier provides for the product and batch.
- Read the supplier’s shipping, return and refund policies.
Joining the Peptide King updates list is not a supplier account and not a supplier approval. Whether a supplier accepts an order, account or partner application is always that supplier’s decision.
Frequently asked questions
What does research use only mean here?
These materials are offered for laboratory research only, not for human or veterinary use or diagnostic use. A research-use label does not itself establish a product’s legal status or override other marketing claims. Peptide King provides no medical, dosing or administration guidance.
Who sets the rules for who can buy?
Each supplier. Eligibility, account requirements, ordering terms and any acknowledgments are set by the supplier on its own site and can change. Peptide King does not decide who a supplier accepts.
How do I get documentation for a specific batch?
Request it from the supplier, or use the documents that supplier currently publishes. Where a supplier has provided an official document to Peptide King, it is listed on the Supplier Hub under that supplier's name; anything not provided is shown as pending.
What does a COA not establish?
A COA reports specified tests on one lot. It is not a safety assessment, not evidence of efficacy, not a regulatory approval, and it does not cover tests it does not list — for example sterility, endotoxin or stability unless those are explicitly reported.
Who handles orders, shipping and refunds?
The supplier you order from. Orders, fulfilment, shipping, returns and refunds follow that supplier's current published policies.
What is Peptide King's role?
Peptide King is an education, marketing and referral hub. It is not the manufacturer, pharmacy, seller, shipper, fulfilment company or primary distributor.
Does Peptide King earn anything if I buy?
Yes, possibly. Some supplier links are affiliate links, and Peptide King may earn a commission on qualifying purchases. That relationship does not change what the supplier's documents say.
