FAQ.

All parcels are tracked and dispatched from Newport, South Wales, and most UK orders land the next working day after dispatch. Chilled items ship with an ice pack. You receive a tracking link by email at the point the label is generated, and parcels are left in a safe place if you're out — no signature required.

Vials are lyophilised (freeze-dried) at the point of dispatch — no cold-chain packaging is required for the transit window.

No. Next working day is a target service rather than a contracted-time service. The vast majority of orders arrive the next working day after dispatch, but our courier does not compensate for late deliveries on this service, and neither do we. If a parcel is lost in transit (tracking stalls for 10+ working days) we replace it; if it is simply slow, we wait with you.

Yes, with a separate-payment step. Pick the international option at checkout and you pay the product subtotal at the normal time; the order lands with shipping marked as "quoted after order". Paul fetches a courier quote and emails you a separate payment link for the postage figure. Once the shipping invoice is paid, the parcel dispatches. Customs paperwork is the customer's responsibility — we cannot pre-clear duties or VAT for every destination.

No. Age is verified at checkout — you confirm you're 18+ before you can pay — so there's no age check at the door. Our courier leaves parcels in a safe place if you're out, and no signature is required on delivery.

Sometimes, yes. If your order is on collection and you've paid online by PayPal, we may offer you one of the lockers outside the clinic alongside the usual collection times. It's offered order by order rather than automatically. Nothing is in a locker until we tell you it is — when your order goes in, we message you on your order thread with the locker number, the code, and the time to collect by. The code is only ever in that message, never in an email, and it's a new one each time; if it doesn't work, just reply and we'll help straight away. Orders that need to be kept cold have a shorter deadline. If you don't make it, we bring the order back inside and you can reply to arrange another collection.

Some of it is, by our supplier rather than by us. The raw material we buy comes from a single manufacturing partner, and that partner has had a number of its compounds analysed by Janoshik Analytical. We hold sixteen of those certificates, covering ten compound families out of roughly eighty catalogue items.

Each certificate reports two things: the measured amount of compound in the sample, and its purity by HPLC. That is the whole of what they cover.

Four things, stated plainly. They were commissioned by our supplier and are issued in the supplier's name, not ours. They test the supplier's raw material, not the individual vial you receive — nothing ties a certificate to a particular vial or shipment. They report amount and purity only, so they say nothing about identity. And most of the catalogue is not covered: where we hold no certificate for a compound, there is none to see.

They are not published on the site. If you want to know what we hold for a particular compound, use the contact form and name it — we will tell you what we have, including when the answer is that we hold nothing for it.

Yes, within the research-use framework. The catalogue compounds are sold strictly for in-vitro and laboratory research, not for human or veterinary use. Sale of research chemicals labelled as such for laboratory research is lawful in the UK for over-18s, which is why every order requires 18+ age verification at checkout. We do not provide dosing protocols, administration guidance, or therapeutic claims of any kind — those would fall outside the research frame.

We don't give a protocol-level answer because we don't give protocols. The general bench observation is that most peptides in solution last days at room temperature, four to six weeks refrigerated at 2–8 °C, and degrade faster with light exposure, repeated freeze-thaw, or oxygen ingress through a punctured septum.

Photograph the damaged parcel and the vial (lot ID visible if possible) before opening anything further and email the photos to support within seven days of delivery. We replace breakages at our cost. If a parcel is lost or arrives damaged, contact us and we'll sort a replacement — you don't need to deal with the courier directly.

Lyophilised research compounds ship sealed and tamper-evident, so they are exempt from the 14-day change-of-mind return under regulation 28(3)(a) of the Consumer Contracts Regulations — we do not accept change-of-mind returns. Opened or punctured vials are non-returnable for the same hygiene reason: once the septum is breached, sterility is no longer assured and we cannot put the product back into stock. If a vial arrives faulty or out-of-spec (visible contamination, broken cake, mismatched lot ID, or a compromised seal on arrival), contact us within 48 hours with the lot ID and photos and we will replace it at no charge. Your statutory rights in respect of faulty goods are not affected.
