Verify this lotWhat you get told, and what you can check
Most suppliers in this category publish a certificate. Very few publish one that names the vial you actually received. Here is the gap.
- No lot numberCovers “the product”, not the vial in your hand.
- Reused across SKUsThe same PDF appears on several listings.
- Purity as a range“>98%” with no measurement behind it.
- No test dateCould be from any production run, any year.
- Nothing to checkNo code to enter, no way to confirm it.

Which size fits your work
Same compound, same lot testing. The larger fills cost less per milligram because they come from a single production run.

Why this matters
A report that names its lot
Synthesis varies between production runs. A certificate covering “the product” covers nothing in particular — only a lot-specific report tells you what is in the vial you received.
A lab with nothing to gain
Testing done in-house, or by a lab with a stake in the outcome, is not an independent check. Ours is contractually separate from manufacturing.
Cold chain that is actually tracked
Peptides degrade with heat and time. Insulated packing matters only if the transit is short and traceable — 24 to 72 hours, FedEx Express Premium, tracked end to end.
Traceability after the sale
Retired lots keep their published report. A supplier that removes past reports when stock runs out is removing the record, not just the listing.
How this lot got its report
The same four steps apply to every reference we sell — no exception for the ones that move fastest.
Sample pulled
A random vial from each production lot is pulled before listing.
Independent lab
Sent to a third-party lab we don't own or invest in — HPLC + mass spec.

Reported use in research
This 10 mg vial supports research into energy balance, glucose control, and body-weight regulation, where the simultaneous engagement of multiple metabolic pathways is of particular interest for metabolic models.
Phase 2 data show dose-dependent metabolic effects, with the highest doses producing body-weight reductions of roughly 24% over 48 weeks alongside improvements in glycemic and hepatic markers. Intermediate doses such as 10 mg are used to characterize the dose-response relationship.
Technical data
Plan your reconstitution
Work out concentration and syringe units for the size you are considering, before the vial ships.
Open the calculator for 5mgIf the lot does not match its report
A shipment that arrives damaged, or whose vial does not match the certificate published for its lot, is replaced or refunded in full. Tell us within 7 days of delivery. Opened vials cannot be returned — these are temperature-sensitive research materials.
Questions
Can I check the lot before I order?
Yes. Every lot code that appears on this site resolves in the verification tool, including retired lots. You do not need an account.
Why is the 20 mg cheaper per milligram?
It comes from a single fill rather than four, so the packaging, testing and handling cost is spread across more material. The compound and the testing are identical.
What is the difference between the plain vial and the + PEN option?
The + PEN option ships with a reusable dosing pen alongside the vial. The peptide, the lot and the report are the same.
How fast does it ship?
Stocked lots leave within 24 business hours, by FedEx Express Premium from our fulfilment centre in Spain, tracked, arriving in 24 to 72 hours.
Do you ship to the United States and Canada?
Yes, both. Canadian orders are subject to 5% GST, calculated at checkout.
What does research use only mean here?
This compound is supplied for in-vitro laboratory research. It is not evaluated by any medicines agency, and it is not intended for administration to humans or animals.
