We may earn a commission. How this works

Prices as listed by the supplier when we last checked; the supplier confirms the final price. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency and serving this store's region, never converted.

How its prices compare

PX1 Research lists in USD. We compared 100 of its 100 listings with the median price per mg across the other stores that list the same peptide in USD and serve the US (70 to 186 stores per product). Prices are never converted between currencies, so this is a like-for-like comparison for a buyer in the US.

Taken together, its typical listing sits 20% above that market median. Behind that: 22 products priced below most stores, 11 within 5% of the median, and 67 products priced above most stores. A store is rarely the cheapest or the dearest on everything, so the product you want matters more than the overall figure.

Price per mg lets vials of different sizes be compared. A higher price can reflect a smaller vial, included shipping, or testing the store pays for; the per-peptide price pages show every store side by side. Prices are as the store listed them when we last checked.

Is PX1 Research legit? What we can check

No website can promise that a supplier is trustworthy. These are the checks we can make from public records, the supplier’s own website and our reviews. They are the same checks as in our guide to spotting an unreliable supplier.

  • Website history (Not known)

    Domain first seen less than a year ago. Most peptide stores are new, so PepFinder does not count this against a store.

  • Ways to get in touch (Not known)

    Contact channels not yet recorded.

  • Written policies (Not known)

    No refund policy or terms recorded yet.

  • Independent testing (Not known)

    PX1 Research states that its products are independently tested, links a certificates-of-analysis or lab-results page, names Kovera. PepFinder has not yet collected or reviewed any of its certificates, so this is the supplier's own claim.

  • PepFinder verification (Not known)

    Not verified. Most suppliers are not; verification is voluntary.

  • Regulator notices and warnings (In place)

    None found in our records.

  • Card payments (In place)

    Card payment shown on the website, which usually allows a chargeback if an order goes wrong.

  • Customer reviews (Not known)

    No reviews on PepFinder yet.

The supplier confirms the final price and availability when you order. Product names, photos, quantities and prices are as publicly listed by the supplier; photos load from the supplier’s own website. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency; prices are never converted between currencies. We do not sell these products and give no guidance on their use.

How PepFinder rates suppliers

What the rating and the customer rating each measure

The PepFinder rating (out of 10) is our own assessment of a supplier across reliability, product selection, pricing, delivery, customer service, website, payment options, packaging and how much information the supplier makes available. Each part is scored from what we can observe on its website, from public records and from customer reviews; parts we cannot observe are left unscored rather than marked down, and the rating is only shown once enough of them are known. It can move as more of the inputs become available.

The customer rating (out of 5 stars) is simply the average of approved customer reviews, shown from three reviews. Reviews are moderated before publication and suppliers can reply but not remove them.

The price comparison puts each listing's price per milligram against the median across every tracked supplier listing the same peptide in the same currency and serving the same region, so a UK store is measured against stores a UK buyer could order from. Prices are never converted between currencies. Suppliers cannot pay to change any of this; claiming or verifying a profile does not change the rating either.
