- Testing transparency36/40
Public 7-category testing rubric grade plus disclosed testing methods plus a named third-party lab. The full range is gated on the vendor publicly naming the tests they run; a high rubric grade without disclosure caps at 18 of 40.
- Operational & regulatory standing15/25
Reflects FDA actions, payment-processor issues, ownership uncertainty, closures, and editorial audit notes the vendor-risk monitor has surfaced. A recent published COA earns a small bonus on top of the operational base.
- Operational stability15/15
Vendor age. 5+ years of operation earns full points; 1 year or less earns minimal credit. Absent foundedYear earns a neutral default; absence of data is not proof of risk.
- Verification tier6/10
Editorial tier assignment based on documentation completeness, response to corrections, and presence of verifiable business address. Tier 1 vendors meet the highest bar.
- Price discipline10/10
Heuristic check on aggressive discounting. Reasonable codes (<=25%) earn full points; 25-40% earns half; >40% off list often signals inventory clearance or churn and earns zero.
- Operates at peptidology.co; the .com TLD is unrelated.

Editorial read of how this vendor lands today
Phase-1 community-sentiment write-up — Pepticker editorial's read of forum activity (r/Peptides, our Discord, prior incidents) at the date below. Not a user-submitted review. The 7-category rubric scoring and trust score are computed separately.
Peptidology routes its testing through an ISO 17025-accredited Scottsdale lab — the accreditation standard used by government and clinical reference laboratories — which gives its HPLC and mass-spec results unusual methodological credibility.
Why we recommend Peptidology
Peptidology operates at peptidology.co (note: the .com TLD is an unrelated business) and tests through an ISO 17025-accredited laboratory in Scottsdale, Arizona. ISO 17025 is the international competence standard for testing and calibration laboratories — the same accreditation required of labs that report to regulatory agencies. In a market where labs are often unnamed or unaccredited, Peptidology's use of an ISO 17025-accredited facility is a meaningful differentiator. Testing score: 6.5 out of 7. Founded 2021.
Testing & COA practices
HPLC purity and mass-spec identity are the two testing panels — the same dual-panel approach used by QSC Peptides with Janoshik, but here done through a US-domestic ISO-accredited lab. Mass-spec identity is the stronger confirmation that a compound is correctly synthesized; it catches wrong-peptide errors that HPLC alone cannot reliably identify. COAs are published per-batch and linked from product pages. Our 4 May 2026 verification confirmed active documentation at peptidology.co.
Product range and pricing
Peptidology operates as a tier-2 vendor with mid-range catalog breadth. Classic research peptides, GLP-1 compounds, and several longevity SKUs are represented. Shipping is $8.95 domestic. Discount code PEPTDOL10 applies for 10% off.
Where they fall short
Sterility and endotoxin testing are absent — two panels that matter for the most rigorous parenteral research applications. The TLD confusion (peptidology.co vs .com) is a minor but real friction point that could send researchers to an unrelated site. Community track record is shallower than Core Peptides given the 2021 founding date. No international warehousing.
Bottom line
Peptidology is a strong choice for US researchers who want ISO 17025-accredited testing documentation — a meaningful quality signal above unlabeled or non-accredited labs. For most dual-panel (HPLC + mass-spec) needs it is directly comparable to QSC Peptides, with the advantage of US-domestic accredited testing. Confirm you're at peptidology.co at checkout. Use code PEPTDOL10.
