About peptides & research use
What are research peptides?
Peptides are short chains of amino acids used across cell and molecular biology as tools to study specific biological pathways. Every product on this site is supplied for laboratory research only — see each product's research dossier for the model-anchored evidence behind it.
Are these products intended for human or animal use?
No. Every product is sold strictly for laboratory, analytical, and research use. None are intended for human or animal administration, and none are presented as having a medical, diagnostic, or therapeutic purpose.
Storage & handling
How should I store my order on arrival?
Products are shipped as lyophilized (freeze-dried) powder, which stores best at −20°C, away from light, until you're ready to work with it. Reconstituted material should be kept refrigerated and used within the timeframe noted in that product's handling section. Full guidance is on each product page.
Do I need to reconstitute the powder myself?
Yes. Each product page includes a reconstitution helper that calculates concentration from the vial size and the volume of solvent you plan to add — a laboratory reference only, not administration guidance.
Why does the powder look different between batches?
Appearance can vary slightly between lots — as a fine powder, a film, or small specks — depending on the lyophilization run. This does not affect the quantity or purity stated on that batch's certificate of analysis.
Orders & shipping
How long does shipping take?
Orders are typically processed within 1–2 business days of payment. Delivery via DHL Express typically takes 1–3 business days within the EU from dispatch. See the Shipping & returns page for full detail, including what happens if a parcel is delayed or held by customs.
Can I track my order?
Yes — a tracking link is emailed as soon as an order ships.
Can I change or cancel my order?
An order can be cancelled or amended at no cost any time before it ships — email [email protected] with the order number. Once an order has shipped, the returns policy applies instead.
Do I need an account to order?
No — checkout works as a guest. Creating an account keeps order history in one place.
Payment
What payment methods do you accept?
Bitcoin (BTC) and Tether (USDT, on the TRON/TRC-20 network) via a self-custody payment processor. See the guide to paying with crypto for a step-by-step walkthrough.
How long is my order held while I pay?
An order awaiting payment is held for up to 7 days before it expires automatically. If a crypto quote expires first, reopening the payment panel on the order page issues a fresh quote at the current rate.
Testing & verification
How is purity tested?
Every batch is tested by an independent third-party laboratory before it's listed. The certificate of analysis for the active batch is linked from its product page, alongside a purity track record across previous lots.
What if a batch is below the purity you published?
Every batch is backed by a purity guarantee — see the Shipping & returns page for how to claim if an independent retest comes in more than 1% below the published figure.
