CJC-1295 No DAC
CJC-1295 (no DAC) is a synthetic modified GHRH analogue of 29 amino acids synthesised as a tetrasubstituted GRF 1-29 variant, studied in GH-axis research for its role in driving short, pulsatile GH release.
A short-acting GHRH analogue studied for pulsatile growth hormone release — investigated in sleep quality, overnight recovery, and steady daily vitality.

How-to-use guide
Read the research protocol
Concise reconstitution, dosing, and handling instructions.
Each release is matched with quality documentation through a documented verification path. Identity, purity, and composition test results sit on the product page before you buy.
Every batch is verified by an ISO/IEC 17025-accredited laboratory before release. Identity, purity, and documentation travel with the product — not behind a form.
Sensitive peptides ship in insulated insulated cold packaging with gel packs sized for a 48-hour transit window, tracked door to door.
Everything worth asking before you order.
Shipping, storage, quality, and when to speak to a clinician — without the runaround.
What proof of quality comes with my order?
Every batch ships with a batch code printed on the vial. The matching independent lab report — identity, purity, and composition — independently lab-tested results — is linked on the product page and also available from your order page after purchase.
Should I speak to a clinician before using a peptide?
We recommend it — especially if you are pregnant, nursing, managing a medical condition, or combining peptides with prescribed medication. Our product pages are educational. They are not medical advice and they do not replace a conversation with a qualified practitioner.
How should I store my order when it arrives?
Sensitive peptides ship cold. Move them to a fridge on arrival (2–8 °C) unless the product page states otherwise. Lyophilised vials can tolerate short transit at ambient temperature but should not be left unrefrigerated for extended periods once delivered.
Are research peptides banned by WADA?
Several research peptides we list — including BPC-157, TB-500, GHRPs, and IGF-1 LR3 — are listed on the WADA Prohibited List under classes S0 (unapproved substances) and S2 (peptide hormones and growth factors). They are prohibited at all times, in and out of competition.
How do I reconstitute a lyophilised peptide vial?
Bring both the lyophilised vial and the bacteriostatic water to room temperature, equalise pressure with a sterile vented needle, then inject the solvent slowly down the side of the vial. Swirl gently — never shake — until clear, and refrigerate at 2–8 °C.
How much bacteriostatic water should I add to my peptide vial?
The calculation is peptide mass (mg) ÷ desired concentration (mg/mL) = volume of bacteriostatic water in mL. For example, a 5 mg vial at 1 mg/mL needs 5 mL; at 2 mg/mL, 2.5 mL. Every Peptyds product page carries a suggested reconstitution volume tuned to the vial size.
How long does a reconstituted peptide stay stable in the fridge?
Most lyophilised peptides reconstituted with bacteriostatic water remain stable for 28–30 days at 2–8 °C, protected from light. A handful of short, fragile sequences — Epithalon among them — drop to roughly 14 days. Never freeze a reconstituted vial.
What side effects are most commonly reported across peptide research?
Across published trials and case series, the most frequent reported events are injection-site reactions (redness, induration, transient discomfort), headache, mild nausea, and temporary fatigue. GLP-1 and dual-agonist class peptides add dose-dependent gastrointestinal effects.
Who should not use peptides?
Peptides are not appropriate for anyone who is pregnant, nursing, planning conception, under 18, managing active cancer, or on immunosuppressants — and competitive athletes governed by WADA must avoid every peptide on the prohibited list. Anyone with a personal or family history of melanoma should specifically avoid melanocortin-receptor agonists.
