EXECUTIVE SUMMARY
A neutral reading of the public record.
American Peptides publishes a large research-use catalog with clear public prices, quantities, policies, contact information, and a lot-number COA lookup. The supplier states that every batch receives identity, purity, content, endotoxin, sterility, and heavy-metals testing, with third-party verification. PSR verified a public lot-specific COA library and lookup system, but did not independently audit every certificate field or establish full current testing coverage across the entire catalog. The strongest evidence is the breadth of lot-linked documentation and traceability; the main limitation is that several laboratory, manufacturing, and compliance claims remain supplier-stated.
01 / DOCUMENTATION REVIEW
Documentation Quality
OBSERVED PUBLIC DOCUMENTATION
Public COA and SDS library · Lot-number certificate lookup · Lot-specific certificate links · Product catalog with quantities and prices · Quality-standard methodology · Shipping and refund policy · Research-use disclaimers · Physical address, phone, email, and support portal
OPEN QUESTIONS
Whether every active lot has a current complete certificate · Whether all supplier-stated testing layers are represented on each public certificate · Independent verification of manufacturing and compliance claims · Resolution of same-day versus 24–48-hour dispatch wording
PSR OBSERVATION
American Peptides provides unusually strong public document access through its lot-number lookup and linked COA/SDS library. PSR verified that lot-specific certificate links are publicly available, while treating catalog-wide testing and compliance claims as supplier-stated unless independently substantiated.
02 / TESTING EVIDENCE
PSR reviewed American Peptides’ public quality-standard page, lot-number verification tool, COA/SDS library, and a lot-specific certificate link. The supplier describes identity by mass spectrometry, purity by HPLC, net peptide content, endotoxin, sterility, heavy-metals testing, and third-party verification. PSR verified public access to the certificate system but did not independently validate every stated testing layer across the full catalog.
Public COA System — Available · Lot Number Lookup — Available · Lot-Matched Certificates — 126 shown during review · Sample Certificate — BPC-157 lot BP5-0803 · Identity Method — Mass spectrometry claimed · Purity Method — HPLC claimed · Endotoxin — Supplier-stated · Sterility — Supplier-stated · Heavy Metals — Supplier-stated · Full Certificate Audit — Not determined
PSR NOTE
American Peptides states that every batch receives a COA and a seven-layer testing review. PSR directly observed the public verification interface, numerous lot-specific COA links, and a sample certificate URL. Because the sampled PDF was not fully machine-readable in this review, individual certificate fields and laboratory independence remain subject to further manual verification.
SUPPLIER-STATED
Claims made by American Peptides that PSR has not independently substantiated beyond supplier-provided information.
DOCUMENT OBSERVED
Information directly displayed in the reviewed laboratory certificates or public supplier documentation.
PSR CONCLUSION
A preliminary interpretation limited to the available public evidence and subject to continued documentation review.
03 / SAMPLE COA OBSERVATIONS
CERTIFICATE 01 / DOCUMENT OBSERVED
TB-500 10mg
Laboratory — Janoshik · Task — #152821 · Batch — YL0426T · Testing ordered — April 28, 2026 · Sample received — May 11, 2026 · Reported purity — 98.855% · Measured quantity — 10.75 mg · Verification QR and key — Present
CATALOG COVERAGE / NOT DETERMINED
Full Catalog Coverage
American Peptides states that every batch receives a COA and displays 126 lot-matched certificates in its public verification system. PSR verified the lookup and sample certificate links but did not establish complete current testing coverage or independently audit every listed product and batch during this review.
These observations apply only to the specific submitted samples represented by the reviewed certificates and should not be generalized to every supplier product or batch.
04 / LOT TRACEABILITY
Lot Traceability
American Peptides provides a public lot-number verification tool and a COA/SDS library organized around lot-specific document links. The verification page reported 126 lot-matched certificates on file during review. This creates strong public document-level traceability, although PSR has not independently observed the complete chain of custody from manufacturing through laboratory submission and customer inventory.
05 / PRICING VISIBILITY
Pricing Visibility
American Peptides publicly displays product prices, vial quantities, availability, shipping information, and catalog categories across roughly 70 listed compounds. Public list pricing: Yes. Package / quantity information: Available. Promotional pricing: Displayed when offered. Shipping information: Available. Inventory status: Displayed on reviewed listings.
PSR OBSERVATION — American Peptides provides strong pricing visibility. Temporary promotions and the confirmed PSR reader code should be separated from standard list prices when making supplier-to-supplier comparisons.
06 / COMPANY & SUPPLIER TRANSPARENCY
Listed supplier — American Peptides · Shipping facility — 9742 St. Vincent Ave, Shreveport, LA 71106 USA · Phone — +1 (318) 347-5336 · Email — support@americanpeptides.us · Public contact form — Available · Support ticket portal — Available · Shipping and refund policy — Available · Research-use disclaimer — Available
PSR OBSERVATION — American Peptides publishes a Louisiana shipping-facility address, phone number, support email, contact form, ticketing channel, customer policies, and research-use limitations.
ITEMS REQUIRING CONTEXT
American Peptides makes broad supplier-stated claims concerning testing coverage, U.S. sourcing or manufacturing, and quality systems. PSR did not independently verify each of those claims. The site also uses both same-day-before-2PM and 24–48-hour dispatch wording, which should be reconciled for consistency.
07 / EVIDENCE CLASSIFICATION
VERIFIED IN PUBLIC DOCUMENTATION — Information directly observed in American Peptides’ public pages, policies, verification interface, or certificate links. SUPPLIER-STATED — Claims made by American Peptides that PSR has not independently substantiated beyond supplier-provided information. NOT DETERMINED — Information for which PSR does not currently have sufficient evidence. These classifications apply throughout this report.
08 / BALANCED ASSESSMENT
DOCUMENTATION STRENGTHS
Product-linked Janoshik report · Batch identifier · Task number and testing dates · Reported purity and measured quantity · QR code and verification key · Clear public prices and quantities · Inventory visibility · Shipping and return policies · Research-use disclaimer · Published company address and phone number
AREAS FOR FURTHER REVIEW
Complete testing coverage across the current catalog · Clear labeling of laboratory attachments · Endotoxin-report availability · Independent confirmation of manufacturing information · Complete chain-of-custody verification · Correction of inconsistent support-email spellings · Long-term historical report availability
PSR ASSESSMENT
Preliminary PSR Transparency Score: 94 / 100 — Excellent Transparency
American Peptides provides excellent public transparency through a detailed catalog, clear pricing and policies, a lot-number verification tool, and a broad public COA/SDS library. These features support an excellent preliminary transparency assessment. PSR does not treat supplier-hosted certificates or stated testing practices as proof of safety, regulatory compliance, complete chain of custody, or suitability for human use. Independent verification of catalog-wide testing, manufacturing claims, certificate fields, and shipping-time consistency requires continued review. This assessment reflects evidence available at the time of review and is not a certification, approval, or recommendation.
