Straight answers for Salt Lake City clients.
Do you have a peptide testing lab in Salt Lake City, UT?
We don't operate a physical lab inside Salt Lake City — Gold Standard Analytics is one independent, ISO 17025-aligned laboratory in Houston, TX, and we serve Salt Lake City and the rest of the Mountain West entirely by mail-in. You submit online, we email a prepaid UPS shipping label, you hand the package to UPS, and the certificate of analysis (COA) comes back to you electronically. Inbound transit from Salt Lake City to our Houston lab runs about 2–3 business days by the prepaid UPS label we email you.
How much does peptide testing cost in Salt Lake City?
Pricing is published and the same for Salt Lake City as everywhere else — no quote calls. A peptide base COA (LC-MS identity + HPLC purity + net peptide content) starts at $189 for standard research peptides and $289 for the GLP-1 class. Safety add-ons are flat (endotoxin $199, sterility $195, heavy metals $169), and there's a bulk discount at 5+ samples. See the peptide service page for the full menu.
How do I send a peptide sample from Salt Lake City for testing?
Start on the submit a sample page — it takes about two minutes. An invoice is issued at submission; once payment clears we email a prepaid UPS waybill with packaging instructions. Ship 5 mg of dry lyophilized peptide (10 mg if you're adding sterility). Inbound transit from Salt Lake City to our Houston lab runs about 2–3 business days by the prepaid UPS label we email you. We handle the customs paperwork for international research shipments.
How long does a peptide COA take for Salt Lake City clients?
Standard turnaround is 5–7 business days from when your sample reaches the Houston lab, plus the 2–3-business-day inbound transit from Salt Lake City. Expedited 48–72-hour service is available on most panels. Every public COA is verifiable by accession number at our COA lookup.
What testing standards and methods do you run on Salt Lake City samples?
Every peptide gets dual-method confirmation: HPLC purity (reversed-phase, UV/DAD at 214 nm) and identity by LC-MS within ±0.1 Da of the theoretical mass, plus net peptide content and TFA / acetate residual. Injectable-grade lots add USP <85> endotoxin (LAL) and USP <71> sterility. We operate to ISO 17025 expectations and GLP data-integrity standards, with weekly instrument calibration.
Can Salt Lake City customers get affordable peptide testing without losing quality?
Yes — our base price bundles identity, purity, and net content on one COA where most labs bill those three separately, so you get a high-quality, dual-method result at a lower all-in price. Nothing about the Salt Lake City mail-in path changes the methods, the instruments, or the public-verifiable COA.
