Supplier documentation profile
Transition Biotech
Transition Biotech is a veteran-owned research-materials supplier headquartered in Tampa, Florida, with refreshed branding, U.S. and international shipping information, and a current 11-item public catalog. PDD tracks standard single-vial USD prices separately from the supplier's build-your-own bundle and wholesale purchasing paths because those options have different quantity and eligibility conditions. Its public COA library identifies products, labeled quantities, batches, report numbers, certification dates, and Kovera Labs as the issuing laboratory. The sampled BPC-157 report includes RP-HPLC purity, LC-MS identity, measured content, endotoxin, microbial sterility, pH, and heavy-metal results. Uploaded reports do not establish which batch is currently shipping, so researchers must match the report to the received label. PDD does not infer compound identities from internal catalog codes such as TBT-2TZ or TBT-3RT.

Procurement details
Business policies not yet documented
PDD has not yet preserved dated, directly reviewable records for this supplier's ship-from location, regions served, processing time, free-shipping threshold, payment methods, or refund and replacement policy. We do not infer those details from a storefront location or checkout availability.
This section will expand into field-level records as eligible supplier policies are documented.

What the reviewed records support
Evidence and COA records last reviewed October 4, 2026. Missing documentation remains visible and is not converted into a negative claim.
| Review field | State | Finding and limitation | Basis |
|---|---|---|---|
| Public COA access | Documented | A no-login COA library links product- and batch-specific original PDF reports and publishes the product, labeled quantity, batch, report number, certification date, and issuing laboratory. | Public COA library + sampled original PDF |
| Lot traceability | Documented | The sampled report identifies batch BPC10-2607-01, and the library instructs researchers to match that batch to the product label. The library also states that the displayed report does not identify current shipping inventory. | COA library + sampled BPC-157 report |
| Laboratory provenance | Documented | The COA library and sampled report name Kovera Labs, include report KVR-2026-9CEBEB and access code J288EKR, and provide a laboratory verification address. | COA library + sampled BPC-157 report |
| Chromatographic purity | Documented | The sampled BPC-157 report records 99.607% purity against a greater-than-98% specification and identifies RP-HPLC with a C18 column and DAD detection at 214 nm. | Sampled BPC-157 Kovera Labs report |
| Molecular identity | Documented | The sampled report records BPC-157 identity confirmation by LC-MS and reports a matching result. | Sampled BPC-157 Kovera Labs report |
| Measured quantity | Documented | The sampled report lists a labeled quantity of 10 mg and an independently reported net content of 11.07 mg. | Sampled BPC-157 Kovera Labs report |
| Sterility testing | Documented | The sampled report records a microbial sterility screen result of no growth. | Sampled BPC-157 Kovera Labs report |
| Endotoxin testing | Documented | The sampled report records a passing endotoxin screen against a stated limit of 0.5 EU/mL or less. | Sampled BPC-157 Kovera Labs report |
| Research-use positioning | Documented | The storefront and site-entry statement limit access and products to qualified laboratory and non-clinical research and exclude human or veterinary use, diagnosis, treatment, and consumer purchase. | Homepage + site-entry statement + research-use notice |
| Marketing consistency | Unresolved | The reviewed storefront uses prominent research-only language and documentation education. PDD has not completed a page-by-page review of every catalog and referral destination. | Homepage + sampled catalog records + referral-program link |

Evidence definitions
Documented
Connected to a directly reviewable public record.
Supplier-reported
Stated by the supplier but not independently confirmed.
Unresolved
The records reviewed do not support a conclusion either way.
Contradicted
Available records or statements materially disagree.
Open verification work
- Confirm that vial batch numbers and QR codes consistently resolve to the corresponding issuing-laboratory record.
- Verify Kovera Labs' legal identity, credentials, methods, and report-verification process independently.
- Expand the audit beyond the sampled BPC-157 report and record panel coverage by current catalog lot.
- Confirm which batch is currently shipping for each exact-product listing; current price and availability do not prove report-to-inventory matching.
- Keep single-vial prices separate from bundle and wholesale tiers, and preserve the stated minimum quantities and buyer eligibility for those programs.
- Do not map coded catalog names to a compound identity without an explicit product specification or batch record naming that identity.
