CJC-1295 Without DAC is a 29-amino-acid GHRH analogue with a research half-life of ~30 minutes, studied for triggering natural pulsatile GH release from the pituitary gland — closely mimicking the body’s own GH-secretion rhythm. Unlike the DAC version (~8-day half-life), this compound’s brief active window is suited to pulse-timed research protocols. It is frequently studied alongside Ipamorelin (as in the Tone Blend) for complementary twopathway GH-release research. Each vial contains 5mg of lyophilized CJC-1295 Without DAC at 99%+ HPLC-verified purity, with a batch-specific Certificate of Analysis available for download. *
CJC-1295 Without DAC
GHRH analogue, Modified GRF 1-29
Mechanism of Action• GHRH Receptor Binding: binds GHRH receptors on pituitary somatotrophs to trigger pulsatile GH release — without the albumin-binding modification of the DAC version.
• Natural Pulsatile GH Pattern: the ~30-min half-life produces a brief, pulse-like GH signal that closely mimics physiological GH secretion — studied for natural-rhythm endocrine research.
• Synergistic Dual-Pathway Research: studied alongside Ipamorelin (GHSR-1a agonist) for two-pathway GH stimulation — GHRH + ghrelin receptor — as in the Tone Blend.
Together these make CJC-1295 Without DAC a key tool in pulsatile GH-release, GHRH-receptor, and short-protocol endocrine research.

CJC-1295 Without DAC binds GHRH receptors on the pituitary and triggers a brief, natural pulse of GH release. Its ~30-minute active window closely mimics how the body naturally releases GH — in short bursts, not continuously. This makes it suited to pulse-timed research and to studies where natural GH rhythm is important. When paired with Ipamorelin, two separate GH-release pathways are activated simultaneously*

GHRH Receptor Activation — Pulsatile GH
Binds GHRH receptors on pituitary somatotrophs to trigger pulsatile GH release. The ~30-min half-life produces a natural, brief GH pulse — the defining characteristic vs the sustained stimulation of the DAC version.
Natural GH Rhythm Research
The short active window closely mimics physiological GH secretion patterns — studied for endocrine models where preserving natural pulsatility is part of the research design.
Synergistic Research with Ipamorelin
This compound is the GHRH component of the Tone Blend — studied alongside Ipamorelin (a GHSR-1a agonist) for two-pathway GH stimulation via complementary receptor mechanisms.

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.
