Peptides AcademyBenzyl Alcohol
What is it?
The antimicrobial preservative in bacteriostatic water (0.9% concentration) that enables multi-dose vial use for reconstituted peptides. Benzyl alcohol prevents bacterial growth during the typical 28-day use window of a reconstituted peptide vial.
Role
Antimicrobial Preservative
Evidence
Established pharmaceutical preservative. Contraindicated in neonates (gasping syndrome at high cumulative doses). Safe at standard concentrations in adults.
Used With
BPC-157
Research-Grade
A 15-amino-acid peptide fragment derived from gastric juice protein BPC, studied extensively in animal models for tissue healing and gut integrity.
CJC-1295 + Ipamorelin
Research-Grade
The most widely used GHRH + GHRP stack — CJC-1295 extends GHRH half-life while Ipamorelin selectively amplifies GH pulses without disturbing cortisol or prolactin.
Ipamorelin
Research-Grade
The most selective GHRP (growth-hormone-releasing peptide) — amplifies GH pulses via ghrelin/GHSR receptor without meaningful cortisol, prolactin, or aldosterone crosstalk.
Sermorelin
Research-Grade
The first synthetic GHRH analog approved for clinical use — GHRH (1-29) NH₂, the minimum active sequence. Shorter-acting than tesamorelin or CJC-1295.
TB-500 (Thymosin β4 Fragment)
Research-Grade
Synthetic fragment of Thymosin β4 investigated for actin-binding, cell migration, and tissue repair across muscle, cornea, and cardiac models.
