METHODOLOGY
The standard we hold ourselves to.
Third-party verification. Every batch. No exceptions.
01
SYNTHESIS
All peptides are synthesized using solid-phase peptide synthesis (SPPS) in our US facility. Raw amino acid inputs are sourced from verified suppliers with full documentation.
02
PURIFICATION
Each batch undergoes reverse-phase HPLC purification to remove truncated sequences, deletion products, and synthesis byproducts.
03
ANALYSIS
Independent third-party laboratory analysis. Every batch receives full HPLC purity analysis, mass spectrometry identity confirmation, and amino acid analysis. We do not self-certify.
04
LYOPHILIZATION
Purified peptide is lyophilized (freeze-dried) under controlled conditions to produce a stable powder. Vials are sealed under nitrogen.
05
PACKAGING
Each vial is labeled, serialized, and sealed with a tamper-evident crimp. The certificate of analysis for that specific batch is included with every shipment.
≥99.5% minimum purity. Verified by HPLC.
On every batch. Every time.
FREQUENTLY ASKED
Common questions.
High-performance liquid chromatography separates the components of a peptide solution to measure what percentage of the sample is the target compound. A result of 99.5% means 99.5% of the material is the peptide you ordered.
