See the COAs → Our Quality Standard
Every single batch undergoes multi-vector third-party validation before clearance.
What 99% pure doesn't tell you.
Purity testing measures one thing. We test for the four things it can't see. Standard HPLC/MS measures the target molecule, not what surrounds it. We screen every batch to ensure absolute laboratory safety.
Residual TFA & Solvents
Trifluoroacetic acid (TFA) is a mandatory reagent in solid-phase synthesis. If unpurified, residual salts alter pH and compromise cell assays. We verify complete counter-ion exchange down to <0.5%.
ICP-MS Metal Screening
Catalysts and cleavage cocktails can leave trace heavy metals. We screen each lot via Inductively Coupled Plasma Mass Spectrometry for Lead, Arsenic, Cadmium, and Mercury down to parts-per-billion.
USP <85> Kinetic LAL
Bacterial endotoxins can trigger false inflammatory responses in receptor binding studies. Every release batch is certified to <5 EU/mg using kinetic chromogenic LAL assays.
Sequence & D-Enantiomers
Racemization during synthesis creates mirror-image peptides that fail target binding. High-resolution MALDI-TOF and tandem MS/MS verify sequence fidelity and optical purity.

The Standard in Research-Grade Peptides
Six commitments. Independently verified. Every one backed by an analytical number, not a marketing claim.
Independent 3rd-Party Testing
Every single batch is verified by ISO-accredited analytical laboratories — HPLC-MS purity, MALDI identity, and endotoxin screening.
99.7% avg purity · last 50 batchesSame-Day Shipping
Orders received before 2:00 PM EST ship the exact same day in temperature-shielded packaging with tracking.
Orders by 2PM EST ship same dayLot-Matched COAs
Every vial is laser-etched with a unique lot ID that corresponds to a downloadable Certificate of Analysis with full chromatograms.
100% lots have downloadable COAsClimate-Controlled Lab Storage
Raw materials and finished lyophilized cakes are preserved at -20°C in industrial freezers with continuous datalogger telemetry.
-20°C industrial cold preservationCryogenic Sublimation
Freeze-drying removes all ambient moisture to <1.0%, preventing hydrolysis and guaranteeing stability during transit.
<1.0% residual water contentAnalytical Transparency
We believe researchers deserve raw data. We publish unedited spectra, mass peaks, and laboratory methodologies publicly.
Full public testing documentationEvery batch survives 18 days of scrutiny before it's ever offered.
Most suppliers ship on a manufacturer's word. We put every single batch through seven independent layers of third-party verification — and if any layer fails, that batch is rejected.
Synthesis
Automated solid-phase peptide synthesis (SPPS) using FMOC-protected amino acids on resin core.
Purification
Preparative HPLC separates the crude peptide from deletion sequences and synthesis truncations.
Lyophilization
Deep-vacuum sublimation freeze-dries the purified solution into a solid, moisture-free cake at -50°C.
HPLC Testing
Analytical reverse-phase HPLC quantifies purity to ≥99% against reference standard calibration curves.
Mass Spec
MALDI-TOF & ESI-MS molecular mass analysis validates exact chemical structure within 0.05 Da.
Endotoxins
USP <71> sterility 14-day incubation and USP <85> kinetic chromogenic testing ensures <5 EU/mg.
Lot Release
QA chemist validates all chromatograms, signs the Certificate of Analysis, and releases batch for researchers.
