Never merged into one number. Some supplier links here are referral links, marked where they appear, which pay Terminus Research when a reader buys. The same terms are open to every supplier in the ledger, apart from the one exception the referral policy page names, participation changes no score, rank, caution, or coverage decision, and a link is not an endorsement.
Peptra Labs' own /lab-reports/ page states plainly: "We do not claim identity testing unless that test exists for the relevant batch," and every one of the 17 substances it covers shows Method: Purity testing only, with no identity or mass-spec line claimed at that summary level. Thirteen of the 30 catalog products carry no published report on that page, and the retatrutide batch, GY035, was tested 20 Mar 2026 while five other compounds on the same page show a batch tested 24 Jul 2026. The named laboratory, Janoshik Analytical, could not be checked directly, its batch report link returning a Cloudflare bot challenge and janoshik.com failing to load at the TLS layer. Has a past buyer managed to pull the Janoshik report for batch GY035 directly, and does its purity figure match the 99.7 percent the product page states?
What the record holds
STATED WINDOW IN DAYS
“typically 7 to 14 business days for cross-border EU delivery”
EU-only service per the FAQ, which answers in its own words that shipping is within Bulgaria and to every other EU country and states We do not ship outside the European Union; a sitewide banner promises free EU shipping over $346. No dispatch cutoff or handling time is published anywhere read, so the transit window is the only timed commitment on record and the stated-window class applies to it under the weaker-when-ambiguous rule.

$138.34
Compound retatrutide 10mg, single vial (no bulk pack listed for this compound anywhere in the catalog)
Listed as GLP-3 (Retatrutide) 10mg, SKU reta
Price as recorded $138.34 USD inclusive of VAT for one 10mg vial (batch GY035, tested 20 Mar 2026, purity of 99.7 percent by the vendor's own summary); no multi-vial pack was found for this compound in the catalog
Read on 2026-08-26. One reading on one day, and prices are not tracked over time here.
This supplier was not part of the Trustpilot reading of 2026-08-25, which covered 59 of the 126 suppliers on file. That is a fact about this publication's coverage, stated rather than left to be read either way.
5 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-26: 1 held, 4 corrected before publication.
A corrected claim is an error of ours that the re-read caught before it reached a page. This line tracks this publication's own accuracy. It says nothing about the supplier.
Dated entries
4 observations on file, recorded 2026-08-26. Newest first, appended and never rewritten.
Catalog and lab-reports architecture read from the live site on 2026-08-26 after the bare domain redirected (301, Location: https://www.peptralabs.com/) to the www host used for every fetch below. The product-sitemap.xml carries 31 URL entries, the /shop/ index page plus 30 product URLs; the WooCommerce store API at /wp-json/wc/store/v1/products returned 30 entries at the same visit, so the two sources agree product for product, with no discrepancy between them on the re-read that closed this record. A dedicated /lab-reports/ page states it holds 19 batch records across 17 substances, so 13 of the 30 catalog products, AOD9604, Bac Water, Cerebrolysin, CJC-1295 DAC, CJC-1295, DSIP, FOXO4, IGF1-LR3, Selank, SLU-PP-332, Thymosin Alpha-1, Tirzepatide and VIP, carry no published report on this page as read today. The page states its own limits plainly: 'We do not claim identity testing unless that test exists for the relevant batch,' and every one of the 17 listed substances shows Method: Purity testing only, no identity or mass-spec line claimed at the summary level. Retatrutide's card on that page shows Batch GY035, test date 20 Mar 2026, purity of 99.7 percent, with a 'View Janoshik report' link. The single product page for retatrutide (there is one page and one 10mg vial size, no other size and no multi-vial pack) repeats the same batch and figure and adds a specifications table: quantity 10mg, purity data 98 percent or higher, the table's own stated floor (a 99 percent figure appears on this page only in its meta-description line, not in the specifications table, and an earlier read conflated the two), salt form sodium, molecular mass 4731.33, CAS number 2381089-83-2, mass and CAS both consistent with retatrutide as documented elsewhere in this research line. The retatrutide description itself reads hedged rather than outcome-framed: it names the GLP-1, GIP and glucagon receptors and cites published literature on energy balance, glucose handling and hepatic lipid metabolism, closing with a disclaimer stating the description is not a claim of effect or of suitability for any person (their wording, described rather than quoted verbatim because the exact phrase trips this publication's own banned-term rule; the disclaimer itself remains live on the page). The laboratory named on every batch card is Janoshik Analytical, reached through 'View Janoshik report' links pointed at verify.janoshik.com.
I attempted to verify the retatrutide batch at its source rather than take the vendor's summary on faith. The link for batch GY035 resolves to https://verify.janoshik.com/tests/121491-Retatrutide_P3UJPG6IQNII; fetched today it returned HTTP 403 with a Cloudflare interstitial page (title 'Just a moment...'), the same non-browser challenge behavior this laboratory's verify subdomain has shown before in this research line's work on a different vendor, so the individual report page could not be read live, and no Wayback Machine capture of that exact URL exists (checked via the availability API, which returned nothing). I then tried to reach the laboratory's own marketing site, janoshik.com, independently of any vendor, to describe its accreditation posture fresh rather than carry a description forward from an earlier session. Every attempt failed at the TLS handshake stage (curl exit code 35, a Windows schannel SEC_E_UNSUPPORTED_FUNCTION error), across the apex domain, the www subdomain, both IP families and both a default and a forced-TLS-1.2 negotiation, while verify.janoshik.com on the same registered domain answered normally (with the 403 challenge above) in the same session, so the failure looks host-specific rather than a general loss of connectivity on my end. I cannot state anything about janoshik.com's current homepage content as freshly read today; that gap is reported here rather than filled with a recalled description. What is corroborated independently of the vendor: Peptra Labs' /merchant-details/ page names the operating entity as Nexus Research Laboratories EOOD, a Bulgarian single-member limited liability company, UIC 208894351, registered office on Str. Vrabcha 17A in Sofia. I attempted to confirm that UIC against Bulgaria's public Commercial Register at portal.registryagency.bg; the request returned a JavaScript application shell rather than a server-rendered record, so the lookup could not be completed by a plain fetch, and a parallel attempt at OpenCorporates was stopped by a CAPTCHA interstitial. Both attempts are reported as inconclusive rather than as a pass or a fail.
Prices and policies read from the live catalog and the WooCommerce store API on 2026-08-26; the store reports every price in USD despite Bulgaria-based, EU-only shipping, confirmed both in the product page's structured priceCurrency field and in the store API's currency_code field. Retatrutide is listed under the name GLP-3 (Retatrutide), SKU reta, one 10mg vial, priced at $138.34 USD inclusive of VAT with no bulk pack found for this compound in the catalog. The 30-entry store-API price sweep, all single-unit listings, no multi-vial kits seen anywhere on this site, also recorded: FOXO4 $194.84, VIP $103.75, Tesamorelin $103.75, NAD+ $103.75, 5 Amino 1MQ $103.75, Tirzepatide $115.28, Thymosin Alpha 1 $92.22, SS-31 $92.22, SLU-PP-332 $83.01, TB-500 $80.69, GHK-CU $80.69, AOD9604 $80.69, Glutathione $74.93, KPV $69.16, Mots-C $69.16, IGF1-LR3 $68.02, CJC-1295 DAC $59.95, Semax $57.63, Selank $57.63, PT-141 $57.63, Melanotan 2 $57.63, Kisspeptin 10 $57.63, Ipamorelin $57.63, CJC-1295 $57.63, DSIP $57.63, Cerebrolysin $69.16, BPC-157 $63.40, Epithalon $51.87, BAC Water $17.28. A sitewide banner promises free EU shipping over $346 and states 'Third-party lab reports published' and 'Research use only' on every page load. The FAQ page states shipping is 'within Bulgaria and to every other EU country' only, typically 7 to 14 business days for cross-border EU delivery, and explicitly 'We do not ship outside the European Union.' Payment: 'Card, crypto, or bank transfer options may appear only when enabled for the current region and order,' shown only at checkout, so the exact gateway for any given order is unconfirmed by this read. Orders can be modified or cancelled within 2 hours of placement only. The age-verification dialog states 18 or older, but it is not an enforced gate: its markup sits inside an inert HTML template element that only browser JavaScript would activate, the page's own configuration object carries age_verify set to no, and a plain script-free fetch is served the full catalog, product page, cart and checkout without the dialog ever intercepting the request, matching what this wave's shopper walk records; I did not attempt to place an order or click past a payment step.
CAUTIONCautions noted, all grounded in pages fetched today. First, coverage: 13 of the 30 catalog products, Cerebrolysin among them, carry no batch record on the /lab-reports/ page at all, a gap the page itself flags rather than hides ('19 batch records... 17 substances'), so roughly two in five products are sold with zero published purity documentation as of this read. Second, staleness within the covered set is uneven: retatrutide's one and only batch, GY035, was tested 20 Mar 2026, more than five months before this read, while five other compounds on the same page, BPC-157, PT-141, Semax, SS-31 and TB-500, show a newer batch tested 24 Jul 2026, about one month before this read, so the benchmark compound is not being kept current at the same cadence as several others on the identical page. Third, the sole named testing laboratory, Janoshik Analytical, could not be independently checked today: the specific batch report returned a bot-challenge page rather than content, and the laboratory's own marketing site failed to load at the TLS layer across every variant tried, so nothing about its current accreditation posture, address or scope of testing can be stated as freshly verified in this session; anything said about that lab elsewhere is at least a day old and is not repeated here as current fact. Fourth, on price format: this Bulgaria-registered, EU-only-shipping vendor prices and displays every product in US dollars rather than euros, an unusual currency choice for a domestic EU storefront, noted rather than explained. Fifth, the Bulgarian Commercial Register entry for the named legal entity could not be independently pulled today (a JavaScript shell on the registry side, a CAPTCHA on OpenCorporates), so the UIC given on the merchant-details page is unconfirmed against a public register, though it was at least stated with the specificity, a real street address and a numbered UIC, that a fabricated entity typically omits.
