FAQ
What are research peptides?
Peptides are short chains of amino acids that act as signalling molecules in biological systems. The compounds we supply are synthetic peptides produced for laboratory research — they are studied for their reported activity at specific receptors and pathways, and each product page cites the primary literature for that compound.
Are these products intended for human use?
No. Everything we sell is supplied strictly for research and laboratory use only. These are not medicines, they are not approved for human or veterinary use, and they are not intended to diagnose, treat, cure or prevent any disease. Purchasers are responsible for ensuring their intended use complies with all applicable laws and institutional requirements.
How do you verify purity?
Every batch is analysed by HPLC through an independent laboratory (Janoshik Analytical). We publish the Certificate of Analysis on the product page as each batch is verified — some are already up, others are still being processed. The COA states the batch identifier, the assay method and the measured purity, so the result traces to the vial you receive rather than to a generic reference sample.
What is a Certificate of Analysis, and why does it matter?
A COA is an independent laboratory report confirming what a batch actually contains. It matters because in research, identity and purity are experimental variables: without batch-level analysis you cannot attribute a result to the compound rather than to an impurity. We publish COAs on the product page as batches are verified, and you can ask us for the report on a specific batch at any time.
How should these compounds be stored?
Our pens are held at 2–8 °C in the dark — refrigerated, not frozen. Published stability work consistently identifies repeated freeze–thaw cycles and prolonged light exposure as the main causes of degradation, so keep them cold and out of the light and follow the storage note on each product page.
Where do you ship, and how long does it take?
We ship worldwide with tracked, discreet packaging. International orders typically arrive within 3–5 working days of dispatch, and you receive tracking as soon as the order leaves us.
Do you offer wholesale or bulk pricing?
Yes. Approved trade accounts get wholesale pricing with quantity-break discounts that scale with order size, applied automatically at checkout once you’re signed in. You can apply through our wholesale page — we’ll ask for your business details and expected volume.
