Research peptides,
radically transparent.
We publish the full third-party testing panel for every batch we ship, not just a purity number on a marketing page.
- Full third-party panel
- Per-lot Certificate of Analysis
- Endotoxins, heavy metals, sterility tested
Featured research peptides
Shipped fast, tracked end to end.
Quick dispatch
Orders ship promptly after manual payment confirmation, with each lot pulled and labeled by hand.
Tracked shipping
Every parcel ships with a tracking number through established domestic carriers.
Status in your account
Order status, tracking, and the exact COA for your lot are linked from your account page.
We test for what others skip.
Most suppliers publish a purity number and stop there. We publish the entire analytical panel for every lot, signed by an independent ISO-accredited laboratory.
01
Purity by HPLC
High-performance liquid chromatography quantifies the target peptide against impurities and truncations. Catches under-spec material that affects assay reproducibility.
02
Identity by Mass Spec
Confirms the molecular mass matches the declared sequence. Catches misidentified, substituted, or degraded peptides masquerading as the right compound.
03
Endotoxins by LAL
Limulus amebocyte lysate assay measures bacterial endotoxin load. Critical for any in vitro work involving cell culture, where endotoxin confounds results.
04
Heavy Metals by ICP-MS
Inductively coupled plasma mass spectrometry screens for lead, arsenic, cadmium, mercury. Catches contamination from synthesis reagents or raw materials.
05
Sterility
Membrane filtration culture confirms the absence of viable microorganisms in the finished lyophilised vial. Required for clean reconstitution.
06
Microbial / Bioburden
Total aerobic and yeast/mold counts quantify any pre-sterility microbial load on raw material. Catches process hygiene failures upstream.
