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.

A dash means the service is not offered; KMD's scope page lists sterility, endotoxin, heavy metals and SEC as outside its HPLC scope. Gold Standard prices are the published catalog. KMD is cheaper per HPLC panel and includes net peptide content; Gold Standard adds mass spectrometry and the microbiological and elemental work on the same accession.
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 returns the certificate in 5 to 7 business days 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). GSA peptide base pricing includes LC-MS/MS identity and HPLC purity. Net peptide content is a separate $29 add-on at every peptide tier. Select the compound and tests in the current intake for a quote.
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 $195, USP <85> endotoxin at $199 and USP <232>/<233> heavy metals at $169 on the same accession as the HPLC panel.
How long does KMD Analytical take?
Standard turnaround is 10 to 12 business days from receipt, with rush at 4 business days for +50% on orders up to four vials, next business day at +100% and same day at +150% by arrangement. Gold Standard's standard is 5 to 7 business days and the panel fee is refunded if the quoted turnaround is missed.
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 $149 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 STE B, Houston, TX 77092, with tours by appointment and a prepaid UPS label included with every order.
