Why Compliance-First Matters

Three layers of protection between you and the vial

  • 01

    Verified suppliers

    Every supplier is vetted against U.S. compounding standards. No anonymous overseas vendors, no unmarked vials.

  • 02

    Domestic lab testing

    Every batch is screened in U.S. labs for molecular integrity, sterility, and contaminants.

  • 03

    Physician-only access

    We verify your license before you ever see pricing or products. The catalog stays closed to consumers, by design.

Multi-Panel Lab Testing

Know exactly what’s in every vial

  • Peptide Purity Testing (Purity, ID, Quantity)

    High-precision analysis and verification ensures that our peptides meet or exceed our stated purity levels, peptide content, and mg quantity count.

  • Bacterial Endotoxin Testing (BET)

    Using both the Limulus Amebocyte Lysate (LAL) assay and the Recombinant Factor C (rFC) assay, our third-party testing provider proudly uses the Charles River Endosafe® endotoxin detection system. These validated methods provide rapid, sensitive, and reliable detection of bacterial endotoxins in accordance with applicable pharmacopeial standard.

  • Heavy Metal Analysis (ICP–MS)

    Comprehensive screening of 77 elements, including all major toxic heavy metals, using Inductively Coupled Plasma–Mass Spectrometry (ICP–MS) with ppm-level quantitative accuracy for sensitive and reliable elemental analysis. This state of the art technology provides and maintains rigorous quality control, analytical precision, and data integrity.

  • Sterility Testing (USP <71>)

    Sterility testing is performed in accordance with USP <71> Sterility Tests using validated membrane filtration or direct inoculation methods, as appropriate, to detect the presence of viable aerobic and anaerobic bacteria, fungi, and yeast. Testing is conducted under controlled aseptic conditions to ensure reliable and compliant sterility assessment.

Order research-use-only peptides

PeptLogic provides a curated range of high-purity research peptides for laboratory investigation and analytical applications. Every compound is synthesized to exceed 99% purity and validated through the absolute highest quality, gold standard, in analyses supported by advanced Agilent LC-MS, MALDI-MS, and HPLC instrumentation. We test for purity, identity, endotoxin, and heavy metals including mercury, lead, cadmium, and arsenic.

Our catalog is built for licensed providers and qualified research institutions conducting in vitro or analytical studies. All products are intended for laboratory research only — we do not supply or endorse the use of any peptide for human or animal administration, medical therapy, or diagnostic purposes.

Advanced Agilent LC-MS with DAD

Advanced Agilent LC-MS with DAD (Liquid Chromatography-Mass Spectrometry with a Diode Array Detector) is a powerful analytical setup by Agilent Technologies. It combines liquid separation, optical UV-Vis light absorption spectra via a Diode Array Detector, and molecular weight/structural data via mass spectrometry.

Key Components and How They Work

LC (Liquid Chromatography)
Separates complex liquid mixtures into individual chemical components as they pass through a specialized column.
DAD (Diode Array Detector)
Shines light through the sample stream and captures full UV-Vis absorbance spectra simultaneously. It helps check peak purity and identifies compounds with light-absorbing groups.
MS (Mass Spectrometry)
Ionizes the separated compounds and measures their mass-to-charge ratio (m/z), providing definitive molecular weight and structural fragmentation clues.

Core Benefits

Dual-Channel Validation
Provides both optical data (from the DAD) and mass data (from the MS) in a single run.
High Confidence in Peak Purity
Confirms if a chromatographic peak contains a single pure compound or co-eluting impurities.
Versatility
Effective for both known target analysis and unknown compound identification in pharmaceuticals, metabolomics, and environmental testing.

At PeptLogic, we provide extensive, third-party verification including costly endotoxin analysis to ensure LPS-free peptides and full sterility testing from our ISO 17025 accredited lab.

Endotoxins are invisible bacterial contaminants that can trigger unintended immune responses, even when no visible impurities exist. Our advanced testing protocol eliminates these risk of threats using medical-grade standards.

Every batch is backed by transparent certificates covering purity, content, endotoxin levels, and sterility. These safeguards aren’t extras—they’re essential.

Quality-Tested

Verified With Third Party COAs

At every step, we prioritize quality by conducting third-party testing on all our products. These tests focus on four key characteristics—identity, purity, sterility, and endotoxicity—ensuring that each batch meets the highest standards for safety and performance, with independent third-party COAs.
