Hulk Stack
Also known as: Ipamorelin plus CJC-1295 stack · GH dual-pathway stack
The Hulk Stack pairs a ghrelin-receptor agonist (Ipamorelin) with a GHRH analogue (CJC-1295). The pairing targets two distinct GH-release pathways simultaneously. Researchers report larger preclinical GH release than either alone. Both are research-tier in the UK.
Why researchers pair these compounds
Growth hormone has two endogenous release pathways: the GHRH receptor (activated by GHRH, Sermorelin, CJC-1295, Tesamorelin) and the ghrelin receptor GHSR (activated by ghrelin and the ghrelin mimetics Ipamorelin, GHRP-2, GHRP-6, Hexarelin). Stimulating both produces additive GH release in published preclinical work.
Ipamorelin is the cleanest ghrelin mimetic, with the lowest cortisol and appetite side-effects in rodent studies. CJC-1295 is a long-acting GHRH analogue available with or without DAC (Drug Affinity Complex) modification. The Hulk Stack typically uses CJC-1295 without DAC for short pulses, or with DAC for sustained activity.
Stack pricing varies. Some UK retailers sell the named bundle. Others list the two compounds separately at no discount. CoA documentation is more important in this category than for healing peptides because the GH-secretagogue lane is more commonly counterfeited.
Mechanism
Ipamorelin activates the GHSR receptor on the pituitary somatotrophs. CJC-1295 (with or without DAC) binds the GHRH receptor on the same cells. Receptor co-activation produces additive GH release with preserved pulsatility in animal work.
Components
Ipamorelin
Selective ghrelin-receptor pentapeptide mimetic. Minimal cortisol and appetite side-effects in preclinical work.
Encyclopedia entryCJC-1295
Synthetic GHRH analogue. With-DAC variant has roughly week-long half-life. Without-DAC variant is short-acting.
Encyclopedia entryWho this is for
- · Researchers studying dual-pathway GH release in preclinical work.
- · Buyers weighing the named bundle versus separate vials.
- · Anyone evaluating retailer CoA practices for GH-secretagogue peptides specifically (counterfeit risk is higher here than for BPC-157 or TB-500).

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.
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
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.

Frequently asked questions
What is the Hulk Stack?
A retailer-branded bundle of Ipamorelin and CJC-1295 (typically without DAC). Names vary by retailer but the underlying compound pair is consistent.
CJC-1295 with DAC or without DAC for the stack?
Without DAC is more common in research-stack contexts because the short half-life preserves natural pulsatility. With-DAC sustains elevated GH and IGF-1 for days but is less physiological. Editorial commentary; not a dosing recommendation.
Is this a legal UK route to GH?
No. Ipamorelin and CJC-1295 are not UK-licensed medicines. They are research compounds. UK clinical practice does not include them in GH-deficiency or longevity protocols.
PeptideClear does not sell, dispense, prescribe, or recommend Hulk Stack for any specific person. This page is editorial commentary on the published preclinical literature and the UK retail landscape. Every research peptide on this page is sold under research-use-only framing.
