Sterile water containing 0.9% benzyl alcohol used to reconstitute lyophilized peptides. The preservative inhibits bacterial growth, allowing multi-use over ~28 days when refrigerated.
Batch
A single production run of a peptide. Each batch is tested independently and ships with its own Certificate of Analysis and HPLC report.
C
Certificate of Analysis (CoA)
An independently issued document detailing a batch's identity, purity, and contaminant testing results.
H
HPLC
High-Performance Liquid Chromatography — the analytical technique used to determine peptide purity, typically reported as a percentage.
I
ISO 17025
International standard for the competence of testing and calibration laboratories. Our reports are issued by an ISO 17025 accredited facility.
IU (International Unit)
On insulin syringes, IU refers to the unit markings (typically 100 per ml). Used to measure volumes when drawing peptide doses.
L
Lyophilized
Freeze-dried. Peptides are shipped in a lyophilized powder form to maximize stability and shelf life.
M
Mcg
Microgram. 1,000 mcg = 1 mg. Most peptide doses are measured in mcg.
P
Peptide
A short chain of amino acids linked by peptide bonds. Smaller than proteins, typically 2–50 residues.
R
Reconstitution
The process of dissolving a lyophilized peptide in bacteriostatic water before use.
V
Vial
A small glass container, usually 2–10 ml, holding the lyophilized peptide under vacuum.
