AOD-9604 vs CJC-1295 vs HGH Fragment 176-191

A three-way comparison to help you find the right peptide for your research goals.

AOD-9604

AOD-9604 is a modified fragment of human growth hormone (HGH fragment 176-191). It was developed to have the fat-reducing effects of growth hormone without the adverse effects on blood sugar or growth.

CJC-1295

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.

HGH Fragment 176-191

HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

Side-by-Side Comparison

Aspect	AOD-9604	CJC-1295	HGH Fragment 176-191
Dose Range	300 mcg–500 mcg	1 mg–2 mg	250 mcg–500 mcg
Frequency	1x daily	Less than daily	2x daily
Cycle Length	12–24 weeks	8–12 weeks	12–16 weeks
Route	subcutaneous	subcutaneous	subcutaneous
Mechanism	Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat accumulation) without affecting blood sugar or growth. Works specifically on adipose tissue through a mechanism independent of GH receptors.	CJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly.	Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors.
Typical Dosage	Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg.	CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily.	Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio.
Administration	Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.	Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.	Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection.
Side Effects	Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.	Water retention, tingling in extremities, potential increase in cortisol and prolactin levels.	Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly.
