This is not unusual in the peptide testing market (most listed labs lack it). Accredited results carry more regulatory weight in formal contexts. Read about lab accreditation standards →

About SR Bio Labs

SR Biolabs is a US-based analytical testing laboratory specializing in Liquid Chromatography–Mass Spectrometry (LC-MS) for purity and potency analysis across pharmaceuticals, nutraceuticals, environmental samples, and industrial compounds. The lab markets itself around LC-MS as the primary analytical technique rather than treating it as an add-on to HPLC — useful for buyers where identity confirmation matters as much as purity quantification.

Standard turnaround is 5 business days from sample receipt.

What sets SR Bio Labs apart

  • LC-MS-first analytical approach — the lab leads with mass spectrometry rather than treating it as a supplementary add-on to HPLC purity work. For complex peptides where identity confirmation is critical (tirzepatide, retatrutide, multi-agonists), this orientation reduces the risk of HPLC-only CoAs that don't confirm what the compound actually is.
  • Broad scope across pharmaceuticals, nutraceuticals, and environmental samples — buyers comparing CoAs against pharmaceutical-grade or supplement-grade references can use the same lab across categories.
  • 5 business day standard turnaround — faster than the 5–10 day window typical for international peptide labs.
Honest disclosures
  • No publicly listed ISO/IEC 17025 accreditation. Standard for the peptide testing market.
  • Specific laboratory address and city are not disclosed on the homepage. Buyers should request the current shipping address directly before sending samples.
  • Pricing is not published on the homepage — quoted per submission.
  • Peptide testing is one segment of a broader analytical service portfolio; confirm peptide-specific methodology and accepted compound classes before submitting samples.
