Frequently asked questions

Yes. Research peptides are legal to purchase in the United Kingdom for in-vitro laboratory research. They are not controlled substances under the Misuse of Drugs Act 1971 or the Psychoactive Substances Act 2016. They are also not licensed medicines under MHRA regulation and are not approved for human or veterinary use. All buyers must be 18 or over and purchasing for legitimate research purposes only.

Qualified researchers, laboratory professionals, and individuals purchasing for legitimate in-vitro research. You must be 18 or older. We do not sell to anyone intending personal use or human consumption, and we reserve the right to cancel any order where misuse is suspected.

We do not routinely request credentials but reserve the right to do so. By placing an order you confirm you are purchasing for legitimate research purposes. Any order where misuse is suspected is cancelled and refunded.

No. We dispatch to UK addresses only and do not ship internationally at this time.

HPLC (high-performance liquid chromatography) quantifies the active peptide content of a sample. A purity of 99% means 99% of the peptide-related material in the vial is the declared compound, measured for that specific lot. Water, salts and counter-ions such as acetate or TFA are not part of that figure, as is standard for research-grade peptides.

Yes. Every lot is tested by an external analytical laboratory using HPLC-UV for purity and mass spectrometry for identity before release. We do not rely on in-house testing as the sole verification. Signed certificates are published in our lab reports library and linked from the product page.

A document issued by the testing laboratory confirming the identity and purity of a specific lot. It carries the HPLC purity result, mass spectrometry identity confirmation, the lot number, test method and column conditions, and the analyst's signature and date.

Every peptide does, linked from its product page. Bacteriostatic water is a solvent rather than a peptide, so there is no HPLC certificate to issue for it. That is the only thing in the catalogue without one.

Identity and purity. HPLC-UV separates the material and measures each component, and mass spectrometry confirms the molecule is the one named on the label. Each certificate states the lot, the analysis date and the analyst who signed it, and prints the chromatogram the figure was read from. They do not measure the fill weight of the vial, so treat the stated quantity as the label claim rather than something the certificate verifies.

Trace TFA may be present as a counter-ion from synthesis. This is standard in solid-phase peptide synthesis and present in most research-grade peptides at trace level. TFA content is not separately quantified unless specifically requested.

Transfer lyophilised vials to a −20°C freezer on receipt. Protect from light and moisture. Let vials reach room temperature before opening, to stop condensation entering the vial. Bacteriostatic water is stored at room temperature, away from direct light.

Draw the required volume of bacteriostatic water (0.9% benzyl alcohol) into a sterile syringe. Insert at an angle and inject slowly down the inside wall of the vial. Never directly onto the powder. Swirl gently until dissolved; do not shake, which can damage the peptide. Once reconstituted, store at 2–8°C and use within the timeframe for that compound.

Every peptide we sell keeps for 28 days at 2–8°C. GHK-Cu can also be split into aliquots and frozen at −20°C for up to 3 months. Do not refreeze thawed material.

Lyophilised vials are held at −20°C in a dedicated freezer from goods-in until the moment of packing, with temperature logged continuously. Orders are not shipped insulated. Lyophilised peptide is stable in transit. Move it to −20°C storage when it arrives.

Every order is dispatched the same day, whatever time it is placed, via Royal Mail Tracked 24. Most UK mainland addresses receive delivery the next working day.

Yes, on every order. There is no cut-off: whatever time you order, it is dispatched the same day.

In plain, unbranded outer packaging with shock-absorbing void fill. There is no indication of the contents, and no compound name, on the outside of the parcel.

No. We dispatch to UK addresses only.

By card (Visa, Mastercard, Amex) or UK bank transfer. Card details go to a secure payment page, never to us. A bank transfer is approved in your own banking app.

Orders can be cancelled before dispatch, but same-day dispatch makes that window short. Contact us immediately via the contact page. Once dispatched, the returns policy applies.

Yes. An order confirmation email is sent immediately, with your order number, an itemised receipt, and links to the published certificate for each product ordered where one exists.

Yes. It pays 30% of the item subtotal on every order placed through your referral link, including every repeat order that customer places. There is no minimum withdrawal, no hold period, and commission is paid by UK bank transfer.

30% of the discounted item subtotal, excluding postage. A £99 order pays £29.70. The rate is flat: there is no starter tier to climb out of and no reduced rate on repeat orders.

Create an account. Your referral link is generated at signup and waiting in the affiliate tab of your dashboard, no application, no interview, no follower requirement. The link can point at any individual product rather than the homepage, and downloads as a branded QR code.

Commission confirms the moment the referred order's payment clears, and is withdrawable from that moment. No 30-day hold, no minimum balance. Withdraw any amount at any time, paid by UK bank transfer.
