Transition Biotech

Refreshed on 2026-10-05 at the vendor’s request, from the live site, its WooCommerce Store API and the public COA library. Catalogue prices are current and in USD: eleven products, all in stock, nine of them single-vial peptides at $44.99–$54.99 per 10 mg vial, which puts the basket at 82.6% of the market median (93.8% in September). The index prices single vials only. Quantity pricing is offered on top of that — build-your-own bundles at 3–4 eligible vials for 10% off, 5–9 for 15%, 10 or more for up to 20% — and a wholesale programme for qualified laboratory and research organisations, reviewed and prepaid, with each SKU in multiples of ten and at least fifty eligible vials in total. Neither tier is shown as a single-vial price here. The COA library is unchanged since the September review: the same ten Kovera Labs certificates, one per product batch, all from a single July 2026 testing round, each printing the lot, purity, labelled and assayed mass; seven are recorded as compound records, the BPC-157/TB-500 blend states only a blend-average purity, and the two code-named products (TBT-2TZ, TBT-3RT) remain held because neither the listing nor the certificate names the compound and the vendor has asked that identity not be inferred from catalogue codes. Report KVR-2026-9CEBEB resolved on the laboratory’s own verify portal in September. Kovera Labs claims no accreditation, names no legal entity, and registered its domain on 2026-01-02, four weeks after the vendor’s. The vendor names Transition Biotech LLC and gives its location as Tampa, FL; the Wyoming registered-agent suite published in September no longer appears, so no street address is on record. Independent reviews: none found. Domain registered 2025-12-07.

PepIndex score

74.3 / 100

3.7/ 5Well documented

Data coverage

87%

Coverage is the share of scored fields we hold and corroborated for Transition Biotech. A score built on a handful of unchecked claims and a score built on forty verified data points are not the same finding, so both numbers are always published together. How coverage is computed.

Is Transition Biotech legit?

Third-party testedComputed from this profile’s stored record, not written by hand

Yes, on the evidence PepIndex holds. We have read 7 certificate records for Transition Biotech, all issued by Kovera Labs, and score it 74.3/100 on 87% data coverage — rank 16 of 57.

  • Across those lots the mean assayed purity is 99.64%, and the weakest single lot came back at 99.37%.
  • 1 of 7 lots assayed below the mass printed on the label.
  • PepIndex checked the laboratory on those certificates, Kovera Labs, for ISO/IEC 17025 accreditation and found none on record.
  • Its certificates can be read without an account, so anyone can check these figures.
  • On the business side it publishes a named legal entity and prices visible without an account.

What this does not tell you

  • PepIndex has located no independent customer reviews for Transition Biotech, so nothing here speaks to its service or fulfilment.
  • A score measures what a vendor publishes about its testing and its business. It does not measure the contents of any vial a buyer actually receives, and PepIndex does not commission its own assays.

Discrepancy is computed as the absolute difference between labeled and assayed mass, divided by the labeled mass. A vendor-published certificate is a claim; only an independently commissioned assay is treated as corroboration.

Strengths

  • Publishes 10 certificates on its own site; 7 read and recorded here
  • Certificates are readable publicly, without an account
  • Testing laboratory named on certificates (Kovera Labs)
  • Operates under a named legal entity (Transition Biotech LLC)
  • Prices are visible without an account

Weaknesses

  • No ISO/IEC 17025 accreditation recorded for the testing lab
  • No physical postal address is published
  • No independent third-party reviews located

Third-party reviews

Not part of the score

Shown for reference and kept out of the score. Review platforms can be gamed — ratings bought, competitors brigaded, profiles removed — so nothing here is treated as evidence of what is in a vial. The score is computed from certificates and documentation alone.

How this score was calculatedEvery signal, its weight and the arithmetic — reconstructable by handrubric v1.12.0View calculation →

Each criterion is scored out of 100 over the signals we could assess, then weighted into the overall figure. Within a criterion, a signal contributes weight × merit × credit: merit is how good the recorded value is, credit is what its provenance earns — 1.00 for a value with a checkable source, 0 for a value recorded without one. A missing signal counts as a partial gap — half its weight — so a vendor that publishes what others leave blank scores higher, while a blank still costs; a value recorded without a source counts in full and earns nothing, so omitting one can never raise a score. A criterion with no data at all — price, when no price could be indexed — contributes nothing and its weight is not handed to the others, so an unmeasured dimension lowers the ceiling rather than disappearing; the coverage figure, shown alongside, reports how complete the assessment is. The weighted criteria sum to the evidence score; for a vendor published since the rule took effect, the published score is that figure times a tenure factor for time in the index, printed in the total below.
