Evidence summary
Prism Labs COAs and evidence
Prism has one of the more complete vendor-published testing displays in this cohort, paired with functioning checkout, current stock data, and clear domestic dispatch promises.
All 130 retained certificates match the issuing laboratory’s records, including five new reports dated October 1, 2026. The prior exact catalog review covered 23 of 29 listed strengths; six strengths lacked certificates. The accreditation claim remains unconfirmed and policy conflicts remain documented. Match the exact product, strength and lot and confirm final checkout terms.
01
Proof Point certificate archive
The Prism Labs quality hub now exposes 130 distinct complete Proof Point Analytical certificates. The October 4, 2026 review added five three-page reports dated October 1 to the 125 previously retained issuer-matched reports. Exact access-code lookups completed in Chrome and matched their specific official PDFs. Analysis dates span April 8 to October 1, 2026. The PeptidePrices library retains all 390 certificate pages and official lookups. The site’s separate ISO/IEC 17025 accreditation claim remains unconfirmed.
02
Six-part testing panel
Reports include identity by retention-time comparison, purity by RP-HPLC, measured content, five heavy metals by ICP-MS, microbial sterility by PCR and endotoxin by USP <85>. All five new reports show heavy metals not detected and no growth on the PCR screen. Each reports endotoxin NMT 0.05 EU/mL as Reported, with no universal pass/fail threshold. The retained purity range remains 99.01–99.99%. A PCR screen is narrower than a compendial sterility test.
03
Representative reports
The 15 previously reviewed blend certificates retain their whole-blend and component quantities. The five new certificates cover Sermorelin 10 mg, Melanotan II 10 mg, GLP-2T 20 mg and 40 mg, and AOD-9604 5 mg. New Sermorelin lot 780030 reports 99.53% purity and 10.18 mg content; GLP-2T 20 mg lot 310626 reports 99.32% and 20.45 mg. The library preserves dated retests separately and lets buyers compare exact products, strengths and lots.
04
Exact catalog coverage
Twenty-three of 29 listed strengths have an exact certificate. The six without one are CJC-1295 No DAC plus Ipamorelin 5mg, MOTS-c 20mg and 40mg, NAD+ 1000mg, Selank 5mg, and Semax 5mg. Twenty-three other retained reports remain library-only, including sprays, BPC-157 files tied to a Wolverine product page, and six water reports that do not state peptide purity. Those files do not create controls on unrelated rows.
05
Customer reviews and company
The exact-domain Trustpilot profile showed 4.5/5 from 74 reviews on October 3, 2026. Recent visible posts praised shipping and ordering; one reviewer questioned product handling, and Prism replied. This is customer-experience context, not a replacement for laboratory testing. Prism describes Texas operations and publishes a support email, telephone, and an Autry Pond Road address in San Antonio without a street number. No owner, legal entity, or founding year was established in the earlier review.
06
Checkout and policies
Checkout displayed card, Google Pay, and Amazon Pay in the reviewed cart. The tested order showed free USPS Ground, while the policy states $5.99 shipping or free delivery above $75. The latest Terms limit eligible addresses to the United States. Shipping and Terms pages differ on whether unopened products have a 30-day return window and contain inconsistent international-order language. Promo PEPTIDEP10 gave 10% off in the checked cart; confirm final terms and total before payment.
07
October customer update
The exact-domain Trustpilot profile showed 4.5/5 from 74 reviews on October 3. Alongside fulfillment/service praise, readable complaints describe documentation, temperature or missing-item issues; a vendor response offers reshipment for a lost order. These order accounts remain separate from the 130 matched Proof Point certificates.
