In our mirror of 1,828 Kovera Labs certificates, Reta One Labs, Beast Labs, Alpha One Aminos and Renova Peptides publish 87 certificates between them, and all 87 sit on the same 21 lot numbers. They trace back to 22 lab tests. 65 of the 87 are additional copies: Kovera reissued an existing result under another brand name with a new report number. The vial-by-vial figures on the copies match the original. This is consistent with one upstream supplier selling the same batches to four storefronts. It does not show who owns any of the four. For a buyer, a certificate under your brand's name tells you what one vial from that lot measured, not that your vial came from it.
Four peptide storefronts, Reta One Labs, Beast Labs, Alpha One Aminos and Renova Peptides, publish 87 Kovera certificates between them. All 87 sit on 21 lot numbers, and they come from 22 lab tests. The other 65 are copies of those tests, reissued by the lab under the other brands' names.
A buyer sees four brands, each with its own testing history. The record holds one testing history, printed four times. Our mirror shows the same pattern for other brand groups, so a raw certificate count overstates how much testing a vendor has done.
Do these four brands share lot numbers?
Yes. Every certificate the four brands publish in our Kovera mirror shares its lot number with the other three. We found no lot that belongs to only one of them.

Per brand, the counts match what our Kovera vendor leaderboard shows: Beast Labs 22, Reta One Labs 22, Renova Peptides 22, Alpha One Aminos 21. Those four rows look like four vendors with clean, independent records. They are 22 tests.
How one test becomes four certificates
Take lot BT200426, a 20 mg BPC-157/TB-500 blend. Kovera issued report KVR-2026-8F88BE to Reta One Labs, certified 15 April 2026. It lists five vials: 99.653, 99.748, 99.546, 99.789 and 99.508% purity, with net content of 22.21, 22.45, 22.01, 22.78 and 22.75 mg. The batch average is 99.649% and 22.44 mg.
Reports KVR-2026-8F88BE-S56 (Beast Labs), -S57 (Alpha One Aminos) and -S58 (Renova Peptides) print the same five vials, the same averages, the same batch, the same cap and crimp colours and the same certification date. Each has its own access code. Beyond the client name and suffix, the copies differ in two small ways: the form line reads "Lyophilized powder (acetate)" instead of "Lyophilized powder", and the per-component breakdown of the blend (11.09 mg BPC-157, 11.12 mg TB-500) appears only on the original.
We compared the results block of every report family in the mirror. Of the 22 tests behind this cluster, 21 families match vial for vial across all copies.
The exception is the 10 mg retatrutide report KVR-2026-CD3D3A (lot RT100326). Its four versions print identical net content for each of four vials (11.79, 11.74, 11.82 and 11.76 mg), but the per-vial purity figures differ by up to 0.057 points between brands, with batch averages of 99.809% (Reta One Labs), 99.792% (Beast Labs), 99.826% (Alpha One Aminos) and 99.808% (Renova Peptides). We do not know why. Identical masses to the hundredth of a milligram rule out four separate tests, so the difference is in how each copy was produced.
Is this a Kovera feature?
It was. A 17 August 2026 write-up of a discussion between labs reports that Kovera removed its general option to issue extra client copies "because it became a headache", after clients asked to submit one vial and request "10 subs".
According to the same piece, Kovera charged $150 for a copy for one-off retail clients, against roughly $550 to $800 for a new panel. Janoshik and Vanguard described similar paid "additional report" services. We have not confirmed those prices with the labs.
All 87 certificates in this cluster predate that change. The latest is dated 13 May 2026.
The 22 tests behind 87 certificates
The table lists each original test. "Brands" counts the client names the result appears under. Purity and net content are the batch averages printed on the original certificate. Every original carries an endotoxin pass and a "No Growth" sterility screen.

Look at the first two rows. Lot RT100326 has two different tests: one issued to Renova Peptides on 10 April (10.52 mg average) and one issued to Reta One Labs on 13 April (11.78 mg average). Kovera copied both to other brands.
So a buyer holding a vial marked RT100326 has two certificates for one lot, and they disagree on fill by more than a milligram. Both pass. They cannot both describe the same vial.
Download the data: all 184 certificates on lots that appear under two or more named brands, with every copy and its report number, are in one CSV file. Our data page describes each column.
Which other brands share lot numbers?
The four-brand group is the largest, but not the only one. Across the mirror, 55 lot numbers appear under two or more named brands. We merged obvious name variants (a vendor and an address at its own email domain, or a capitalisation change) before counting.
| Brand group | Shared lots |
|---|---|
| Alpha One Aminos, Beast Labs, Renova Peptides, Reta One Labs | 21 |
| Optimum Formula, RCHQ, WWPeptides | 19 |
| Axiom Labz, Orbitrex Peptides, Synthesis Peptides | 4 |
| Instant Peptides, Peptide Outsource | 3 |
| Ion Peptide, Phase One Labz | 3 |
| BioEdge Research Labs, Thryv Medical | 2 |
| BioEdge Research Labs, Ion Peptide | 1 |
| Glacier Aminos, Instant Peptides | 1 |
| Peptide Partners, Stack Science LLC | 1 |
The second group follows the same shape: 19 original tests, all issued to RCHQ between 25 February and 26 April 2026, with 42 copies under Optimum Formula and WWPeptides. In the mirror as a whole, 120 report numbers carry an -S suffix.
Why would different brands share a lot number?
There are three ordinary explanations, and the data fits at least one of them.
- A shared upstream supplier. A manufacturer or wholesaler sells one batch to several storefronts, each with its own label. A comment under the August write-up describes a US supplier that "allows wholesalers to have the COAs put in their name" for bulk buyers. We have not identified the supplier behind any group in this table. Our earlier piece on shared COA URLs and upstream supply documents the same pattern at Janoshik.
- A paid copy from the lab. The lab reissues one result under several client names for a fee. The -S suffix shows this happened for 65 of the 87 certificates here.
- Lot fields entered by the client. Labs print the batch the client supplies. They do not inspect a warehouse. The August write-up reports Kovera's view that many grey-market products lack "enough unique identifiers" to tie one tested vial to everything later sold under that batch claim.
None of these requires the four brands to share an owner. Common ownership would also produce this pattern, and so would a turnkey seller supplying product, certificates and storefront together, which the same write-up says exists. We have not seen a public record that ties these four brands to one company, and we do not claim one. For why operators run several storefronts, see why peptide vendors run alias clusters.
Why does one lot appear on 15 compounds?
A second pattern in the mirror is one lot string spread across many products. After removing the placeholders "N/A" and "NA" and merging spelling variants of compound names, 23 lot strings appear on three or more different compounds. The largest:
| Lot | Compounds | Certificates | Client |
|---|---|---|---|
| EVO5212026 | 15 | 16 | Evolabs Research |
| JA2026164 | 14 | 23 | PuraSynth |
| ZEN51826 | 10 | 12 | Zenergy |
| ZEN5426 | 9 | 12 | Zenergy |
| 0526 | 9 | 11 | Peptorin Nutrition & Wellness |
| 0326-1 | 8 | 10 | Trident Aminos |
22 of the 23 sit under one client name, or under no name at all, so this is a different problem from the brand groups above. EVO5212026 reads like a date (21 May 2026), and the Evolabs certificates on it are dated 23 to 29 May. ZEN51826 reads like 18 May 2026, and all 12 Zenergy certificates on it were analysed on 31 May. A lot field that names a date or a submission tells you when the vendor sent samples, not which production batch a vial came from. Peptides synthesised separately do not share a manufacturing lot.
What a shared COA means for you
A certificate under your brand's name with an -S suffix is a real Kovera record. It is also a copy. Three things follow.
- Count tests, not certificates. Four brands with 22 certificates each have 22 tests between them. When you compare vendors on testing history, strip the -S copies first.
- Match the lot, then distrust the match a little. If your vial says TZ300326 and the certificate says TZ300326, the certificate describes one sample from a lot your vendor says it holds. The lab did not confirm that your vendor holds it.
- Read dates. These tests ran in April and May 2026. A storefront still pointing to them in October may be selling the same lot, or may not.
The verification steps on our Kovera Labs legitimacy page still apply: open the lab's verifier yourself, enter the report number, and compare client, product, lot and date. Our analysis of 1,828 Kovera certificates has the wider data.
For the same pattern at Janoshik, see our look at whether Nexaph, EZ Peptides and Ameano are the same company.

Frequently asked
Do Reta One Labs, Beast Labs, Alpha One Aminos and Renova Peptides sell the same product?
Their Kovera certificates point that way. All 87 certificates the four publish share 21 lot numbers and trace to 22 tests, issued between 10 April and 13 May 2026. Matching lot numbers and identical vial results fit a common upstream supplier. Certificates cannot show whether the vials each brand ships today come from those lots.
Are these four peptide brands owned by the same company?
We have not seen a public record that says so. Shared lot numbers show a shared source of tested material, or a shared paperwork arrangement with the lab. White-label resale between unrelated businesses produces the same pattern. Ownership would need a corporate filing, a court record or a statement from the companies.
What does the -S number on a Kovera report mean?
In this data set, a report number ending in -S plus digits (for example KVR-2026-8F88BE-S56) is a copy of an earlier report issued under a different client name. The copy keeps the lot number and the vial-by-vial results of the original and gets its own access code. It is the same analysis, not a second test.
Is a shared COA fake?
Not by itself. The 65 copies here resolve on Kovera's verifier and carry the original test's numbers. The problem is weight, not authenticity: four certificates on one lot are one data point, not four. Treat a copy as evidence about the lot, then check that the lot on your vial matches it.
Why does the same lot number appear on 15 different peptides?
In our mirror, 23 lot strings appear on three or more compounds, and 22 of those sit under one client name or none. They look like date or order codes typed into the lot field, such as EVO5212026 on 15 compounds from one vendor. That makes the field useless for matching a vial to a test.
How do I check whether my vial matches a Kovera COA?
Read the lot printed on your vial. Open koveralabs.com/verify yourself and enter the report number from the certificate. Check that the client, product, lot and date match. If the lot on the record differs from the lot on your vial, the certificate does not describe your vial.
