Core Terminology You Must Know
Understanding peptide research vocabulary is crucial for safe and effective protocols. These terms appear in every research context and vendor communication.
Preparation and Storage Terms
Lyophilized: Freeze-dried peptide powder form that extends shelf life and stability. Most research peptides arrive lyophilized and require reconstitution before use.
BAC Water (Bacteriostatic Water): Sterile water containing 0.9% benzyl alcohol as a preservative. The standard solvent for peptide reconstitution, extending solution stability.
Reconstitution: The process of mixing lyophilized peptide with BAC water to create an injectable solution. Requires precise measurement and sterile technique.
Administration Methods
SubQ (Subcutaneous): Injection into the fatty tissue layer beneath the skin. The most common peptide administration route, using insulin-type syringes.
IM (Intramuscular): Injection directly into muscle tissue. Used for specific peptides requiring deeper tissue absorption.
Intranasal: Administration through nasal passages, common for cognitive peptides like Selank and Semax.
Measurement Units
mcg (Micrograms): Common peptide dosing unit. 1000 mcg equals 1 mg. Critical for accurate dosing calculations.
IU (International Units): Measurement for peptides like hCG, based on biological activity rather than weight.
Quality Indicators
COA (Certificate of Analysis): Lab report showing peptide purity, typically 95%+ for research-grade compounds.
