Also: CJC-1295 with DAC, CJC-1295 DAC, Long-acting GHRH analog

CJC-1295 (with DAC) is a long-acting GHRH analog that uses a Drug Affinity Complex (DAC) linker to bind to albumin in the bloodstream, extending its half-life to 6–8 days. A single weekly injection produces sustained GH and IGF-1 elevation — very different from the pulsatile pattern of CJC-1295 No DAC. Best for steady anti-aging and body composition protocols.

CJC-1295 No DAC (also called Modified GRF 1-29) is a short-acting GHRH analog that produces a natural, pulsatile release of growth hormone closely mimicking the body's own GH secretion pattern. Unlike the DAC version, it has a short half-life (~30 min) and is typically injected 2–3× daily for a more physiological GH pulse.

Also: Growth Hormone Releasing Peptide-2, KP-102

GHRP-2 is a potent synthetic hexapeptide growth hormone secretagogue and one of the strongest GHRPs in terms of GH pulse amplitude. It stimulates GH release through both pituitary and hypothalamic mechanisms, producing larger GH pulses than GHRP-6 with somewhat less appetite stimulation.

Also: Growth Hormone Releasing Peptide-6, SKF-110679

GHRP-6 is the original synthetic growth hormone releasing peptide — a hexapeptide that triggered the entire field of GH secretagogue research. While newer GHRPs (GHRP-2, Ipamorelin) have superior selectivity, GHRP-6 remains the most studied and has additional gastroprotective properties similar to BPC-157.

Also: Examorelin, EP-23905

Hexarelin is the most potent of the GHRP-class growth hormone releasing peptides, producing the largest GH pulses of any synthetic secretagogue studied. It also has unique cardioprotective properties that are independent of GH release, acting directly on cardiac tissue via CD36 and GHS-R1a receptors.

Also: NNC 26-0161

Ipamorelin is a highly selective growth hormone secretagogue peptide that stimulates GH release without significantly affecting cortisol, ACTH, prolactin, or aldosterone levels. It is considered one of the cleanest GH-releasing peptides due to its selectivity.

Also: Ipamorelin CJC Combo, CJC/Ipa, GH Peptide Stack, Ipamorelin + CJC-1295 No DAC

The Ipamorelin + CJC-1295 No DAC combo is one of the most popular and well-researched GH peptide stacks. Ipamorelin triggers a clean GH pulse while CJC-1295 No DAC amplifies and extends it — together producing a powerful, natural-pattern GH release with minimal side effects.

Also: Ibutamoren, Ibutamoren Mesylate, L-163,191

MK-677 (Ibutamoren) is an orally active, non-peptide ghrelin receptor agonist that stimulates GH and IGF-1 secretion. It is unique among GH secretagogues in that it is taken orally and has a long duration of action (~24 hours), making it highly convenient. Extensively studied in elderly patients for GH deficiency and muscle wasting.

Also: GHRH 1-29, Sermorelin Acetate, GRF 1-29

Sermorelin is a biologically active fragment of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce and secrete growth hormone (GH) in a pulsatile, physiologically natural manner. Unlike exogenous HGH injections, Sermorelin works upstream — coaxing the pituitary to release its own GH rather than replacing it externally. This approach preserves the natural feedback loop and avoids pituitary suppression.
