KMD Analytical vs Gold Standard Analytics
KMD Analytical is an independent peptide lab in Chatsworth, California, a division of KMD Group LLC. It runs one technique: reversed-phase HPLC with diode-array detection at 214 nm on an Agilent 1260 Infinity II, and reports three numbers on every certificate — identity against a certified reference standard, chromatographic purity as area percent, and net peptide content in milligrams per vial. Certificates carry a QR code and a SHA-256 hash, and its verifier accepts the PDF itself to prove the file has not been altered. It states its limits in plain language on its own site: no mass spectrometry, no sterility, no endotoxin, no heavy metals, no SEC aggregate testing, no SARMs or steroids, and no controlled substances. Core pricing is $150 a sample, dropping to $125 at five and $100 at ten, with standard turnaround of 10 to 12 business days.

What KMD Analytical does well
- States its scope limits outright: its own FAQ and scope page say it does not run LC-MS, sterility, endotoxin, heavy metals or SEC, and will refer the work out.
- Net peptide content in milligrams per vial is included on every certificate, not sold as an add-on.
- PDF-level verification: drop the certificate file into its verifier and it confirms the file is byte-identical to the lab's record.
- Published per-sample pricing with automatic volume tiers at 5 and 10 samples, no retainer and no minimum.
- Blend pricing is explicit — standard rate plus 50% per additional active, with one row per active on the certificate.
- Rush at 4 business days, next business day and same day are all published with their surcharges.
- Publishes a specimen certificate and guides, including one on purity versus net peptide content.

Endotoxin: $150 per vial, USP <85> kinetic chromogenic LAL. Sterility: Not offered, per its scope page.
How do you verify a KMD Analytical certificate?
Enter the certificate ID or scan the QR code on its verify page, and drop in the PDF to check it against the file the lab sealed. (kmdanalytical.com/verify) Check a certificate with the laboratory that issued it; Gold Standard Analytics certificates resolve at /verify.

Its site makes no ISO/IEC 17025 claim, and its scope page says it is not FDA-registered and holds no DEA registration. Gold Standard Analytics is not ISO/IEC 17025 accredited.
Questions about KMD Analytical and Gold Standard Analytics
Is Gold Standard a KMD Analytical alternative?
Yes, for peptide identity, purity and net content, and it covers work KMD does not do. KMD runs RP-HPLC-UV only. Gold Standard adds LC-MS/MS identity confirmation, ICP-MS heavy metals, GC-MS residual solvents, USP <85> endotoxin and USP <71> sterility on the same accession, and targets 5 to 7 business days for the certificate instead of 10 to 12.
How much does KMD Analytical charge for peptide testing?
$150 a sample for identity, purity and net peptide content, $125 a sample at five or more and $100 at ten or more, with blends billed at the standard rate plus 50% for each active beyond the first (kmdanalytical.com/pricing, effective July 2026). Gold Standard charges one flat price for any peptide or blend, GLP-1s included: $129 per sample for HPLC-MS identity and purity, or $199 with net content (mg per vial).
Does KMD Analytical run mass spectrometry?
No. Its FAQ states plainly that it does not run mass-spec confirmation; identity is a retention-time and UV spectral match against a certified reference standard. Gold Standard confirms identity by LC-MS/MS on an Agilent 6490 triple quadrupole to within ±0.1 Da in addition to retention time, which separates peptides with similar UV spectra.
Does KMD Analytical test sterility, endotoxin or heavy metals?
No. Its scope page lists heavy metals by ICP-MS, sterility, endotoxin and SEC aggregate content as outside its HPLC scope and offers referrals. Gold Standard runs USP <71> sterility at $199, USP <85> endotoxin at $149 and USP <232>/<233> heavy metals at $199 on the same accession as the HPLC panel.
Can I verify a KMD certificate here?
No. KMD certificates verify at kmdanalytical.com/verify by certificate ID, and its verifier will also check an uploaded PDF against its record. Gold Standard certificates verify here by accession number and are listed in a public library anyone can search by compound, lot or accession.
Does KMD Analytical test SARMs or kratom?
Its scope excludes SARMs, steroids, somatropin and any scheduled material; it does quantify plant alkaloids. Gold Standard tests SARMs from $129 and kratom and botanicals from $119, and holds no DEA registration either, so neither lab can accept Schedule I–V material.
Where is KMD Analytical located?
9631 Topanga Canyon Pl, Chatsworth, CA 91311, as a division of KMD Group LLC. Gold Standard operates from 5151 Mitchelldale St A10, Houston, TX 77092, with tours by appointment and a prepaid UPS or FedEx label with every order, billed at carrier cost.
