CJC-1295 (without DAC) vs MENT
Well Studied vs Emerging
synergistic Mechanism-based · 49% MENT helps manage estrogen conversion from CJC-1295 (without DAC). This is a common and recommended combination. Adjust AI dose based on bloodwork — avoid crashing estrogen.
Molecular Data
CJC-1295 (without DAC) MENT
Weight 3,367.97 Da 288.43 Da
Half-life 30 minutes - 2 hours ~40 minutes (acetate ester)
Chain 30 amino acids —
Type GHRH analog 7-alpha-methyl-19-nortestosterone (C19H28O2)
Key Benefits
CJC-1295 (without DAC)
01 Preserves natural GH pulsatility
02 Minimal side effects
03 No receptor desensitization
04 Precise GH release control
05 4x greater receptor affinity than native GHRH
MENT
01 Approximately 10x more potent than testosterone, allowing effective results at very low doses (5-25 mg/day)
02 Does not cause the sexual dysfunction associated with other 19-nor compounds like nandrolone
03 Can potentially serve as a standalone base, replacing testosterone in hormone replacement protocols
04 Rapid clearance of the acetate ester allows quick dose adjustments and fast resolution of side effects upon discontinuation
05 Powerful lean mass accretion and strength gains relative to dose
06 Under investigation as a reversible male hormonal contraceptive
07 Resistance to 5-alpha reductase means it does not convert to DHT, potentially sparing hair follicles from direct DHT-mediated damage
08 Robust suppression of gonadotropins (LH/FSH), which is therapeutically useful in contraceptive applications
Dosing Protocols
CJC-1295 (without DAC)
100-300mcg per injection / 2-3 times daily (morning, post-workout optional, bedtime)
Anti-Aging/Wellness 100mcg 2x daily (morning and bedtime)
Body Composition 100-150mcg 3x daily (morning, post-workout, bedtime)
Maximum GH Release 200mcg 2-3x daily with GHRP
Sleep Enhancement 100-200mcg Once at bedtime
MENT
5-25 mg/day (acetate) / Daily or split into 2x daily (acetate ester)
TRT Replacement - Low Dose 5-10 mg/day Daily (or split into 2 injections per day)
Moderate Anabolic Protocol 10-15 mg/day Split into 2 injections per day
Higher Dose - Advanced 15-25 mg/day Split into 2 injections per day
Side Effects
CJC-1295 (without DAC)
Generally well-tolerated at recommended doses
Temporary facial flushing/warmth (5-10 minutes post-injection)
MENT
Estrogen management difficulty -- 7-alpha-methyl-estradiol is harder to control with conventional aromatase inhibitors
Water retention and bloating, particularly at doses above 10 mg/day
Elevated blood pressure, often linked to water retention and estrogenic load
Mood changes including irritability, emotional sensitivity, or anxiety (frequently estrogen-related)
Profoundly suppressive of the HPG axis -- LH and FSH driven to near-zero even at low doses
Injection frequency burden (daily or twice-daily with acetate ester)
Mild acne and oily skin
Increased appetite
Contraindications
Active cancer (due to growth-promoting effects)
Diabetic retinopathy
Severe kidney disease
Pregnancy or breastfeeding
Prostate cancer (active or history of hormone-sensitive prostate cancer)
Breast cancer in males or females
Pregnancy or potential for pregnancy
Severe hepatic impairment
Polycythemia (hematocrit above 54% at baseline)
Uncontrolled hypertension or severe cardiovascular disease
Uncontrolled heart failure
Known hypersensitivity to trestolone or any formulation components
