Research peptide vendor
A US research supplier with open pricing across 51 listings, roughly half of them SARMs, prescription medicines and post-cycle compounds rather than peptides. Prices are among the lowest we have recorded, and there is no certificate of analysis, purity figure or lot number anywhere on the site.

Lyophilised and liquid research compounds in three catalogues: Peptides, Liquids and Lab Supplies. The Peptides shelf is conventional. The Liquids shelf is SARMs, aromatase inhibitors, SERMs and prescription-only medicines.
$4.00
$25.99Each product page carries one sentence: the product is prepared for laboratory research use only and may not be used for other purposes. That is the whole of it. No attestation at checkout, no terms page, no privacy policy, no shipping or refund policy. For a shop selling compounds of this kind, that is unusual.
Graded by whether we could confirm it ourselves or are only repeating what the vendor states. A vendor's honesty about its own testing is a different question from what a published trial shows, so this is a separate scale from the evidence grades on our guides.
They are. All 51 listings carry a price, a strength and a stock status, and nothing asks you to register before showing them. After the four brands we pulled this month for gating their catalogues, this is worth saying plainly: Vector shows you the shop.
Where the vendor states this23 of the 51 listings sit under Liquids, and that shelf is SARMs (RAD140, LGD-4033, MK-677, MK-2866, S-4, S-23, YK-11, GW501516), aromatase inhibitors and SERMs (anastrozole, letrozole, exemestane, tamoxifen, clomiphene, raloxifene, toremifene), and prescription medicines (tadalafil, sildenafil, finasteride, levothyroxine, liothyronine, pramipexole). Clenbuterol is there too, at $27.99.
Where the vendor states thisThis is the homepage headline and we could not find anything behind it. There is no certificate of analysis on the site, no lab named, no purity percentage on any product page and no lot or batch number anywhere. Finnrick holds no test record for the brand either. The claim may be true. Nothing published lets you check it.
Where the vendor states thisThe sentence is printed on every product page we opened, including the clenbuterol and prescription-drug listings. It is one line rather than the multi-point attestation some vendors put at checkout, and nothing stops the order either way, but it is stated where a buyer will see it.
Where the vendor states thisEvery listing carries a properties and identifiers block: molecular formula, molecular weight, monoisotopic mass, CAS number, PubChem CID, InChI, InChIKey, SMILES and the IUPAC name. The clenbuterol page gives CAS 21898-19-1, which is clenbuterol hydrochloride and matches the form described. This is reference data rather than test data, and it is still more than most vendors bother with.
Where the vendor states thisBoth are promised on the homepage, along with a loyalty points scheme. We have no order to check them against, and there is no shipping policy page to read the terms off, so this stays the vendor's word.
Where the vendor states thisNo lab is named, no purity figure is printed and no lot number appears on any listing. For a shop whose strapline is Where Quality and Accuracy is Everything, there is no published accuracy to read.
The site has three catalogue pages and product pages, and that is all. There is nothing setting out what happens if an order arrives wrong, late or not at all.
Cardarine was abandoned in development after rodent studies found tumour formation across multiple organs at a range of doses. It is still widely sold as a research chemical, and the risk is not disclosed on the listing.
Levothyroxine, liothyronine, tadalafil, sildenafil, finasteride and pramipexole are prescription drugs. The research-use sentence is the only thing separating the listing from a pharmacy counter.
A beta-2 agonist banned in sport and not approved for human use in the United States, with a narrow margin between the dose people take it for and the cardiac effects it causes.
They share one file, named image-coming-soon-placeholder.png on the vendor's own server, showing a camera icon and the words Image Coming Soon. You cannot see the vial, the label or the cap seal before ordering.
Ipamorelin at $19.99. BPC-157 at $25.99. Tesamorelin at $26.99, against $83.99 for the same compound at Olympex Solutions. These are not small gaps.
A price that low can mean several different things, and the site doesn't help you tell them apart. It can mean a lean operation passing on the saving.
It can also mean a smaller fill than the label says, which is the commonest finding in independent peptide testing and the reason Finnrick reports dose accuracy separately from purity. Or it can mean material of a lower grade.
Olympex prints a measured purity percentage and a lot number on every product card before you buy. Arcane marks which lot is currently shipping. Vector prints the molecular weight of the compound it means to sell you, which is a fact about chemistry rather than a fact about the vial.
We aren't saying the vials are short. We're saying that at this price the question matters more than usual, and this is the one vendor in our catalogue that publishes nothing you could answer it with.
The shop is called Vector Peptides and 23 of its 51 listings are not peptides. That is worth knowing before you browse.
SARMs. RAD140, LGD-4033, MK-2866, S-4, S-23, YK-11 and MK-677, plus GW501516 at $57.99. Cardarine is the one to single out: development was abandoned after rodent studies found tumours forming across several organs, and it has been on the WADA prohibited list for years. None of that appears on the listing.
Post-cycle and hormonal compounds. Anastrozole, letrozole, exemestane, tamoxifen, clomiphene, raloxifene and toremifene. This is a recognisable post-cycle therapy shelf, and its presence tells you who the shop expects its customers to be.
Prescription medicines. Tadalafil, sildenafil, finasteride, levothyroxine, liothyronine, pramipexole and ketotifen. Levothyroxine and liothyronine are thyroid hormones with a narrow therapeutic window, normally dosed against blood work.
The research-use-only sentence sits on each of these pages exactly as it sits on the BPC-157 page. One line, the same line, doing a great deal more work on some pages than others.

It's a real shop with a real catalogue, open prices and chemical identifiers on every listing. Nothing about it reads as a front. What it doesn't have is published evidence about what is in the vials: no certificate of analysis, no named lab, no purity figure, no lot number. Checkable as a business, unverifiable as a supplier.
Every fact above traces to one of these pages, published by the vendor itself and checked on October 30, 2026. Vendor policy pages change without notice, so if something here looks out of date, it probably is.
