Hexarelin vs Nandrolone
Well Studied vs FDA Approved
monitor Mechanism-based · 51% Both Hexarelin and Nandrolone can elevate prolactin. Combined prolactin elevation increases risk of sexual dysfunction and gynecomastia. Monitor prolactin levels and consider a dopamine agonist (cabergoline).
Molecular Data
Hexarelin Nandrolone
Weight 887 Da 274.40 Da (base)
Half-life 1-2 hours ~6-12 days (decanoate)
Chain 6 amino acids —
Type Synthetic hexapeptide 19-nortestosterone steroid (C18H26O2)
Key Benefits
Hexarelin
01 Most potent GHRP for GH stimulation
02 Powerful synergy with GHRH peptides
03 Cardioprotective effects via CD36 receptor
04 Enhanced muscle growth and strength
05 Improved fat metabolism
06 Better recovery and tissue repair
07 Maintains natural GH pulsatility
08 Stable against proteolytic enzymes
Nandrolone
01 Significant increases in lean muscle mass with a favorable anabolic-to-androgenic ratio
02 Enhanced collagen synthesis and joint lubrication, reducing joint pain and improving connective tissue integrity
03 Increased bone mineral density through direct osteoblast stimulation
04 Improved nitrogen retention and protein synthesis for accelerated recovery
05 Stimulation of erythropoietin production, increasing red blood cell mass and oxygen delivery
06 Lower androgenic side effects (hair loss, acne, prostate enlargement) compared to testosterone
07 Clinically demonstrated efficacy in treating anemia of chronic renal failure
08 Potential neuroprotective properties observed in preclinical research
Dosing Protocols
Hexarelin
100-200 mcg per injection / 2-3 times daily for optimal GH pulses
GH optimization 100 mcg 2-3x daily
Enhanced results 200 mcg 2-3x daily
With GHRH (synergy) 100 mcg each 2-3x daily
Cardioprotection 100-200 mcg 1-2x daily
Nandrolone
100-200 mg/week (therapeutic) / 1x per week (decanoate) or 2-3x per week (NPP)
TRT Adjunct - Joint Support 50-100 mg/week 1x per week (decanoate)
Therapeutic - Anemia / Wasting 100-200 mg/week 1x per week (decanoate)
Performance Enhancement - Moderate 200-400 mg/week 1x per week (decanoate) or split into 2 injections
NPP Protocol - Shorter Cycle 200-350 mg/week Every other day or 3x per week
Side Effects
Hexarelin
Increased appetite (less than GHRP-6)
Water retention
Tingling or numbness
Tiredness after injection
Mild headache
Nandrolone
Suppression of natural testosterone production (profoundly suppressive, more so than testosterone alone)
Water retention and bloating (less than testosterone at equianabolic doses)
Erectile dysfunction and reduced libido without concurrent testosterone ('deca dick')
Increased appetite and weight gain
Mild acne and oily skin (less pronounced than testosterone)
Elevated hematocrit and hemoglobin (erythrocytosis)
Injection site pain or discomfort
Mild mood changes (some users report increased emotional sensitivity)
Contraindications
Active cancer or history of cancer
Pregnancy or breastfeeding
Pituitary disorders
WADA prohibited for competitive athletes
Prostate cancer (active or history of hormone-sensitive prostate cancer)
Breast cancer in males or females

Nephrosis or the nephrotic phase of nephritis
Severe hepatic impairment
Hypercalcemia
Known hypersensitivity to nandrolone or any formulation components
