CJC-1295

CJC-1295 (with and without DAC modification)

CJC-1295 is a 30-amino-acid synthetic analogue of GHRH (Growth-Hormone-Releasing Hormone). It is sold in two forms: with DAC (Drug Affinity Complex, a maleimidopropionic acid modification that binds the peptide to serum albumin) and without DAC. With DAC, half-life extends from minutes to roughly 6 to 8 days. Without DAC, action is short-lived.

What the molecule is

  • · 30-residue GHRH analogue developed for sustained GH release.
  • · DAC variant adds a maleimidopropionic acid linker that covalently binds the peptide to serum albumin in vivo.
  • · Acts on the pituitary GHRH receptor to stimulate endogenous GH release.
  • · Frequently paired with ghrelin mimetics (Ipamorelin, GHRP-2) in research stacking because the two receptors act on different pathways.

What the literature shows

UK regulatory status

  • · Not a controlled drug under the Misuse of Drugs Act 1971.
  • · Not scheduled under the Psychoactive Substances Act 2016.
  • · No UK marketing authorisation as a medicine.
  • · Sold legally as a research chemical under research-use-only framing.

Researchers wanting named-stack bundles (Wolverine, KLOW, Glow) and CoAs that can be QR-verified to a named third-party lab.

XL PeptidesCoA: strong

Research peptide retailer · Wolverine Stack £29.99, BPC-157 single from £14.99

Nottingham-based research peptide retailer (Bio Research Ltd, since 2024). Bundles and stacks are the hero SKU (Wolverine BPC-157 + TB-500, Tesamorelin + Ipamorelin 3:1, KLOW, Glow). Janoshik third-party CoAs published per batch with QR-code verification. 10-vial bulk packs alongside singles. Wholesale tier above 11 vials.

Best for per-batch CoA library

Pure Peptides UKCoA: strong

Research peptide retailer · BPC-157 5mg £13.99, TB-500 5mg £36

Long-established UK research peptide supplier. 12 years trading, 15,000+ customers. Operates a public CoA subdomain (coa.purepeptidesuk.com) with downloadable per-batch certificates linked from every PDP. Dual-tier purity (Standard vs Premium with endotoxin LAL + heavy-metal testing on Premium).

Researchers who want transparent third-party HPLC batch documents and a less hyped brand voice.

Research peptide retailer · Per peptide, varies

UK research peptide retailer with third-party HPLC plus transparent batch documentation. Plays the credibility lane alongside Pure Peptides UK and Tide Labs.

Researchers who weight UKAS lab accreditation specifically and want the loudest external-verification claim in the segment.

Tide LabsCoA: partial

Research peptide retailer · Per peptide, varies

UK research peptide retailer leaning on UKAS-verified HPLC as the sole-in-UK trust claim. Narrower catalogue than UKPeptides or Pure Peptides UK but the lab-verification angle is the loudest in the segment.

Best for classic peptides catalogue

Peptides UKCoA: partial

Research peptide retailer · Per peptide, varies

Long-trading UK research peptide retailer (2012). Heavy on classic compounds (BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, MOTS-c). No GLP-1, no cosmetic line. CoA gated via on-site contact form (request lab report per product). On-site CusRev reviews 5.0 average, not Trustpilot. Reconstitution calculator on-site.

Buyers who want personal owner-accountability via WhatsApp and prefer CoAs visible in product images rather than gated. Strong stack catalogue.

Dr PeptidesCoA: partial

Research peptide retailer · BPC-157 from £18.99, Wolverine Stack discounted

Family-run Newcastle research peptide retailer (Rian, Victoria, Leah Redman). Owner-fronted WhatsApp on every page. CoAs photographed into the product gallery (COA in image) rather than gated. Heavy on named-stack bundles (Wolverine, Hulk, Ultimate Bundle). Crisp live chat sitewide. Personal accountability is the trust play.
