Molecular Weight: 3647.954 Da | 30 aa + DAC Linker | Form: Lyophilized | Purity: 99%+ HPLC
CJC-1295 DAC is a long-acting GHRH analogue derived from the first 29 amino acids of GHRH, modified with a Drug Affinity Complex (DAC) — a lysine linker that enables albumin binding and extends the research half-life to ~8 days. Unlike CJC-1295 Without DAC (~30- min half-life), the DAC version is studied for sustained pituitary GH-pulse stimulation suitable for weekly research protocols, protein-synthesis pathway research, and bone/sleep-cycle models. Each vial contains 5mg of lyophilized CJC-1295 DAC at 99%+ HPLC-verified purity, with a batch-specific Certificate of Analysis available for download. *
CJC-1295 DAC
GHRH analogue with Drug Affinity Complex
Mechanism of Action• Albumin Binding via DAC: The DAC lysine linker covalently binds circulating albumin, preventing rapid enzymatic degradation and extending the research half-life to ~8 days.
• GHRH Receptor Activation: Binds GHRH receptors on pituitary somatotrophs to stimulate pulsatile GH secretion while preserving the natural GH pulse rhythm.
• Sustained GH-Axis Research: Studied for sustained downstream IGF-1 pathway activity and GH-axis research, including protein-synthesis, bone-density, and sleep-cycle models.
Together these make CJC-1295 DAC a key tool in long-acting GHRH, pituitary-axis, and sustained GH-release research.

FEATURED INGREDIENTS
All Ingredients
DAC (Albumin Binding)
The Drug Affinity Complex utilizes a lysine linker to bind albumin in the bloodstream, providing an extended research half-life of approximately 8 days, compared to roughly 30 minutes for the non-DAC version.
Pituitary GH-Release Research
Studied for its ability to bind GHRH receptors on the pituitary gland, specifically to trigger natural, pulsatile growth hormone release in various endocrine research models.
Weekly Research Protocols
The extended half-life makes this compound uniquely suited to once-weekly research protocols, in direct contrast to the multiple-daily-dosing regimens required for standard CJC-1295.
PRODUCT BENEFITS
-
Dual Receptor Agonist (GLP-1 + GIP) GIP-backbone peptide that activates both GLP-1 and GIP receptors simultaneously — the defining feature that sets GLP2-T apart from single-receptor GLP-1 analogues.
-
Appetite Control Research Studied for helping the body feel full by sending "stop eating" signals from the gut to the brain — relevant to appetite and energy-intake research.
-
Blood Sugar Research Researched for signaling the pancreas to release insulin when blood sugar is high — studied in glucose-regulation and beta-cell research models.
-
Stomach Emptying Research Studied for slowing how fast food leaves the stomach, helping control how quickly nutrients enter the blood in metabolic models.
-
Heart & Brain Research Examined in cardiac-function and neuroprotection models, including amyloid-beta research relevant to neurological pathway studies.
-
99%+ HPLC-Verified Purity Independently verified by third-party labs via HPLC and LC-MS; batch-specific COA and SDS available pre-purchase.

CJC-1295 DAC is a GHRH analogue with one key modification — the DAC lysine linker — that lets it attach to albumin in the blood. Once attached, albumin acts as a carrier, keeping the compound circulating for ~8 days instead of degrading in ~30 minutes. During this time, it continuously signals the pituitary gland to release GH in natural pulses — studied for a sustained GH-axis effect suited to weekly research protocols.*

GIP + GLP-1 Dual Receptor Activation
Simultaneously binds and activates both the GIP receptor (GIPR) and GLP-1 receptor (GLP-1R) — providing a two-channel metabolic signal that is studied for additive and synergistic effects compared to single-receptor agonists.
Appetite Signaling & Insulin Secretion
Studied for sending gut-to-brain fullness signals through both receptor pathways and for stimulating glucose-dependent insulin release — contributing to metabolic balance research.
Adiponectin Pathway & Insulin Sensitivity
Researched for increasing adiponectin levels and improving the body's response to insulin in metabolic pathway models — effects attributed to GIP receptor activation that GLP-1-only compounds do not provide.

FAQs
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide studied extensively in preclinical and in vitro research models. It is primarily researched for its role in tissue repair, collagen synthesis, wound healing, gene expression modulation, hair follicle biology, and antioxidant defense pathways.
Lyophilized means the compound has been freeze-dried — water is removed under vacuum to produce a stable powder. This process significantly extends shelf life and preserves compound integrity during storage and shipping. Lyophilized peptides are the research-grade standard because they maintain purity far longer than liquid formulations.
Each batch of GHK-Cu is independently verified at ≥99% purity using HPLC (High-Performance Liquid Chromatography). Identity is further confirmed by LC-MS (Liquid Chromatography-Mass Spectrometry). A batch-specific Certificate of Analysis (COA) is available for download before purchase.
Store lyophilized GHK-Cu at −20°C upon receipt. Keep protected from light, heat, and moisture. Do not open the vial until needed for your research protocol. Under proper storage conditions, lyophilized GHK-Cu maintains compound integrity for up to 24 months.
No. Peptides Verse does not provide reconstitution, dosing, or administration guidance of any kind. All reconstitution protocols are the sole responsibility of the qualified researcher or institution receiving this compound. This product is strictly for in vitro and laboratory research use only.
Yes. A batch-specific COA is available for every vial of GHK-Cu sold by Peptides Verse. The COA includes HPLC purity data, LC-MS identity confirmation, lot number, and testing lab details. It can be downloaded directly from the product page before or after purchase.
GHK refers to the free tripeptide (Glycyl-L-Histidyl-L-Lysine) without copper. GHK-Cu is the copper-chelated form — where a Cu² ion is bound to the tripeptide. The copper-chelated form is the biologically active version studied in most published research on wound healing, collagen synthesis, and gene expression modulation.
No. GHK-Cu from Peptides Verse is strictly for in vitro research and laboratory experimentation only. It is not intended for human or animal use of any kind. By purchasing, the buyer confirms they are a qualified researcher or institution and accepts full responsibility for safe handling and use.
All orders are shipped via FedEx with temperature-appropriate packaging to protect compound integrity during transit. Packaging is discreet — plain FedEx or UPS with no product branding on the exterior. Orders placed before 2 PM EST ship same business day.
Due to the nature of research chemicals, all sales are final once a vial has been opened or the seal broken. If you receive a damaged or incorrect item, contact support@peptidesverse.com within 48 hours of delivery with your order number and photos.
