Frequently Asked Questions
Answers for Serious Researchers
Research use & compliance
What are research peptides?
Research peptides are short chains of amino acids supplied for scientific, analytical and laboratory research. They are labeled for research use only and are not intended for human or veterinary consumption, medical use, or any therapeutic application.
What does "for research use only" mean?
It means the product is supplied solely for laboratory research and analytical purposes. It is not for human or veterinary use, diagnostics, therapeutics, cosmetic use, or as a dietary supplement.
Do you provide dosing, usage or reconstitution guidance?
No. We do not provide dosing, usage, protocol or reconstitution guidance. These products are supplied for laboratory research only, and it is the researcher's responsibility to handle all materials under their institution's safety protocols and applicable law.
Are your products legal to purchase?
They are supplied as research-grade compounds for laboratory and analytical research, not as drugs, supplements or food. They are not FDA-approved for treating any condition and are not for human or animal consumption. Buyers must be 21 or older and are responsible for compliance with local, state and federal law.
Who are these products for?
Licensed researchers, laboratories and scientific institutions handling materials for controlled laboratory research.
Do I need bloodwork before considering peptide therapy?
Bloodwork may help a qualified healthcare professional understand what is happening beneath the surface and identify potential safety concerns. Appropriate testing depends on the compound and may include metabolic, hormonal, liver, kidney, glucose, lipid, or other relevant markers.
Quality & Certificates of Analysis
Do your products come with a Certificate of Analysis (COA)?
Yes. Every lot ships with a batch-specific Certificate of Analysis that documents the lot number, test methods, measured values and specifications. You can request the COA for any lot before you buy on the Request a Lot COA page.
How is purity and identity verified?
Each lot is assessed for identity by LC-MS and for purity by RP-HPLC assay, with net peptide or fill content, water content (Karl Fischer), acetic acid (ion chromatography), related substances, and bacterial endotoxins (LAL assay). Copper content (ICP-MS) is verified for GHK-Cu; pH and residual solvents (ICH Q3C) are reported for NAD+. Certificates are compiled by Pure Compound Lab.
What is "net peptide content" and how is it different from purity?
Assay purity is the percentage of the target compound among related substances, measured by HPLC. Net peptide content is how much actual peptide is in the vial by weight, after water and counter-ions such as acetate are accounted for. A vial can be high purity and still contain less net peptide than the label weight, which is why both appear on the COA.
Where do I find the lot number?
The lot number is printed on the vial and matches its Certificate of Analysis. Provide it on the COA request form to receive the exact report for your vial.
What does "lyophilized" mean, and why is my vial a powder?
Lyophilization is freeze-drying: moisture is removed under vacuum so the compound stays stable during storage and transit. A dry powder or "cake" in the vial is normal for a lyophilized research compound.
How should I store the products?
Store lyophilized compounds at -20 °C, protected from light and moisture. Retest window is 24 months from manufacture. Exact storage is stated on each product's COA.
Ordering & shipping
How long until my order ships?

Payment & support
I didn't receive an order confirmation email.

Do you offer wholesale or institutional pricing?
Yes. Labs, institutions and bulk buyers can reach our team through the Supply Partner Assessment for wholesale pricing and account setup.
You don't list a compound I need. Can you source it?
Contact us. We expand the catalog based on researcher demand and can share information on upcoming availability.
