Overview

Product details.

CJC-1295 with DAC 5mg
What happens when you covalently attach a GHRH analog to serum albumin? You get a peptide that stays active for days instead of minutes. The Drug Affinity Complex (DAC) — a maleimidopropionic acid derivative — forms a thioether bond with albumin’s Cysteine-34 residue in experimental systems, creating a sustained-release peptide-protein conjugate. The result is a GHRH receptor agonist with an effective half-life of approximately 6-8 days, compared to 30 minutes to 2 hours for the non-DAC version.
Research-Grade Compounds

Sustained vs pulsatile

This is the fundamental tradeoff. Without DAC, you get pulsatile GH release that mimics endogenous patterns. With DAC, you get sustained GH elevation lasting days. The two profiles answer different research questions. Published comparative studies have examined the downstream consequences of each secretion pattern on IGF-1 levels, body composition markers, and tissue-specific receptor activation.

The GHRH analog family

Sermorelin: unmodified, ~11 min half-life. CJC-1295 No DAC: tetra-substituted, 30 min-2 hours. CJC-1295 with DAC: albumin-conjugated, 6-8 days. Three durations, one receptor target. Heritage Labs USA stocks all three.

Quality and testing

Every Heritage Labs compound is manufactured to research-grade standards and shipped in protective packaging.
