The fine print, kept readable
Affiliate disclosure
As an Amazon Associate we earn from qualifying purchases.
In plain English: the product buttons on this site are Amazon affiliate links. If you click one and buy something, Amazon pays us a small percentage. You pay exactly the same price as if you'd found the product yourself. This commission is the site's only revenue — we don't sell your data, run sponsored placements, or accept payment from brands for better positions in the catalog.
What we don't sell
PepPrep does not sell, stock, broker, or ship peptides, hormones, or so-called "research chemicals," and we hold no stock of any kind — every link goes to Amazon, who take the payment and ship the item. Most of the catalog is ordinary equipment: syringes, cases, coolers, scales, pads. The mixing fluids are the exception worth naming. Bacteriostatic Water for Injection, Sterile Water for Injection and Bacteriostatic Sodium Chloride are labelled pharmaceutical products, and in several countries — including the US, where they are marked "Rx only" — they are prescription-controlled rather than general merchandise. We list them because Amazon lists them, and Amazon applies whatever restrictions attach to your delivery address; but you should treat them as pharmacy items and not assume availability where you live implies anything about your own position. Where a product category is restricted where you live (a few US states limit over-the-counter syringe sales, and some countries restrict them to pharmacies), Amazon applies those restrictions at checkout — we have no ability to bypass them and wouldn't want one.
Medical disclaimer
Nothing on this site is medical advice, and we are not clinicians. Our guides and calculator describe products and arithmetic — what supplies are called, how they're commonly used, and how unit math works. They are not a recommendation to use any substance, and they can't account for your situation. For anything involving your health, medications, or injections, consult a licensed clinician, and always follow the labeling and instructions of the actual products you buy.
Privacy
No cookies, and no tracking company. We don't set cookies, we don't use Google Analytics or any advertising tracker, and we never sell or share anything about you.
Visitor statistics. We keep simple, self-hosted statistics — how many people visited, which pages they read, which links they clicked, roughly which country, and what kind of device — stored on our own server and nowhere else. It is deliberately built so we cannot work out who you are from it: no cookies are set, your IP address is never written down, and a visitor is recorded as a one-way scrambled code made from a secret that changes every night, so the same person cannot be recognized from one day to the next.
Email, only if you ask for it. If you type your address into a sign-up box, it goes to our email provider so we can send you supply guides and occasional offers from us and brands we work with. That's the only reason we'd have your address, every email has a one-click unsubscribe, and we don't sell the list.
Sending you to the right Amazon. So the buy buttons point at your own country's Amazon store, we work out which country you're in — from your browser's timezone, and where it's set up, from your IP address looked up against a database on our own server. Your IP is used for that lookup and never written down, and the answer is only ever a two-letter country code. Nothing is sent to any outside service. The country database is IP Geolocation by DB-IP, used under CC BY 4.0.
Your settings. The site remembers your chosen shopping region and whether you prefer light or dark, in your own browser. Those never leave your device.
Who holds this, how long, and your rights. The site operator named on this page is the data controller for everything above. Our legal basis is legitimate interest for the visitor statistics and the country lookup — both are needed to run and improve the site, and neither builds a profile — and your consent for the mailing list, which you withdraw by unsubscribing. Statistics rows are deleted automatically after two years; email addresses are kept until you unsubscribe.
If you are in the UK or EU you have the right to ask what we hold about you, to have it corrected or deleted, to object to processing, to receive a copy, and to complain to your data protection authority (in the UK, the ICO). Write to the address in About and we will answer within a month. In practice there is usually nothing to send: the statistics contain no name, no email and no account, and the visitor code is not reversible.
One point of honesty about that code: it is made from your IP address and browser details plus a secret that changes nightly, so we genuinely cannot work out who you are from it and it does not persist from one day to the next. That makes it pseudonymous rather than truly anonymous, which is why it is covered by everything in this section rather than exempt from it.
The site is otherwise static pages with no accounts. When you click through to Amazon, you're on Amazon's site under Amazon's privacy policy, and Amazon knows you arrived from our link — that's how affiliate crediting works. Our web host keeps standard server logs (IP address, page requested, time) as virtually all hosts do.
Terms of use
The content here is provided "as is," free, in the hope that it's useful. We work to keep product information accurate, but listings, prices, and availability on Amazon change constantly and the listing on Amazon always wins. We're not liable for how third-party products are used, for errors on linked pages, or for decisions made based on our general information. If you rely on a number, verify it. If something here looks wrong, tell us and we'll fix it.
