Every order is dispatched from our UK warehouse. We don’t drop-ship from overseas suppliers — your order is picked, packed, and shipped from where it’s stored.

Orders placed before 2pm on a working day are dispatched the same day with 24-hour tracked Royal Mail shipping. You’ll receive a tracking number by email as soon as your order leaves our warehouse.

Yes — we ship across the EU and selected international destinations. International orders are limited to 4 vials maximum per shipment to comply with customs requirements. Delivery times vary by destination, typically 5–10 working days.

If you’re ordering from outside the EU and aren’t sure whether we ship to your country, get in touch before placing the order.

Yes. All orders ship in plain, unbranded packaging with no external indication of the contents. The return address shows our company name only, and there are no product labels visible from the outside.

All UK orders are sent via tracked, insured Royal Mail. If your package shows as delivered but you haven’t received it, or if it arrives damaged, contact us within 7 days of the expected delivery date and we’ll arrange a free redelivery at no additional cost to you.

Photos of damaged packaging or contents are helpful for processing redelivery requests quickly.

Every batch we receive arrives with manufacturer HPLC purity testing as standard, confirming ≥99% purity.

As a second layer, we periodically commission independent verification through Janoshik Analytical — a third-party lab we don’t own and can’t influence. We publish those reports openly when they’re completed.

Where available, yes. Independent Janoshik test reports are published on the relevant product pages and updated as new verifications are completed. If you’d like documentation for a specific batch number you’ve received, email us with the batch number and we’ll send you what we have on file.

All products are supplied as sterile lyophilised (freeze-dried) powder in sealed glass vials with rubber stopper closures and crimped aluminium caps. This format preserves potency for storage and reconstitution.

Lyophilised peptides should be stored in a cool, dry place away from direct sunlight. For long-term storage, refrigeration (2–8°C) is recommended. Once reconstituted with bacteriostatic water, refrigeration is required and shelf life is reduced.

Specific storage guidance for each compound is included in the product description.

We stock bacteriostatic water in 3ml and 10ml vials for reconstitution use. We do not sell syringes or other consumables — these should be sourced through appropriate medical or laboratory supply channels.

Lyophilised peptides typically have a shelf life of 24 months from manufacture when stored correctly. Each vial is labelled with an expiry date — we don’t ship anything within 6 months of expiry.

We offer two seamless payment options at checkout:

• Open banking — pay directly from your bank account, authorised through your banking app in a few taps. No card details, no manual transfer setup. Most payments clear in seconds.
• Cryptocurrency — we accept major cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), and stablecoins (USDT, USDC). Live exchange rates and payment instructions are shown at checkout.

Both options are processed through regulated providers — open banking via FCA-authorised payment initiation services, and crypto through a vetted payment processor.

Open banking lets you pay us directly from your bank account in a few taps — no card numbers, no copying sort codes and references manually.

At checkout, you select your bank from the list and get redirected to your banking app to authorise the payment with Face ID, fingerprint, or your usual login. The amount and reference are pre-filled, so there’s nothing to mistype. Once approved, you’re returned to our site and your order is confirmed instantly.

Payments are processed through an FCA-authorised payment initiation provider regulated under PSD2.

We accept Bitcoin (BTC), Ethereum (ETH), and the major stablecoins USDT and USDC. At checkout you’ll be shown a live exchange rate, the wallet address to send to, and a QR code. Orders are confirmed automatically once the transaction is detected on-chain.

If you’d like to pay with a cryptocurrency not listed, get in touch before ordering and we’ll let you know if it can be accommodated.

Yes. Neither payment method requires you to share card details or sensitive financial information with us.

With open banking, the payment is authorised inside your own banking app — we never see your login, card details, or account credentials. The connection is encrypted and regulated under PSD2 / FCA rules.

With cryptocurrency, you send payment from your own wallet directly to ours. No personal financial information is exchanged at any point.

Larger sizes of multi-vial products (e.g., MOTS-c 40mg, Retatrutide 30mg) are priced at a meaningful per-mg discount compared to single vials. For genuinely bulk laboratory orders, get in touch directly and we’ll discuss pricing.

Yes. A VAT-compliant invoice is issued automatically for every order and emailed to the address on file. If you need a copy or an additional invoice with specific business details, email us with your order number.

All products supplied by Momentum Peptides are sold strictly for in-vitro laboratory research purposes only. They are not intended for human or veterinary use, consumption, injection, or any application outside of qualified laboratory settings.

Research use only. Not for human or animal consumption.

No. We do not and cannot provide dosing guidance, protocol advice, or recommendations on how to use these compounds. Our products are sold for in-vitro research only, and any application beyond that is outside the scope of what we supply or advise on.

Researchers conducting laboratory work should refer to peer-reviewed scientific literature for technical specifications.

The compounds we supply are not currently classified as controlled substances under UK law and do not require a specific licence to purchase for laboratory research purposes. However, regulations vary by country and by compound — if you’re ordering internationally or have any legal questions, you should verify the regulatory status in your jurisdiction before ordering.

No. Our products are not pharmaceutical-grade and are not licensed for clinical, medicinal, or therapeutic use. They are research chemicals supplied for in-vitro laboratory study only.

No — guest checkout is available. However, creating an account lets you track orders, view your order history, save addresses for faster checkout, and access invoices.

Due to the nature of research compounds and the strict quality control requirements involved, we do not accept returns under any circumstances. Once a product has left our warehouse, we cannot accept it back into stock.
