Ipamorelin vs Propranolol
Well Studied vs FDA Approved
monitor Mechanism-based · 47% Both Ipamorelin and Propranolol affect insulin sensitivity or blood glucose. Monitor fasting glucose and HbA1c. Consider adding an insulin sensitizer (metformin/berberine).
Molecular Data
Ipamorelin Propranolol
Weight 711.85 Da 259.34 Da
Half-life ~2 hours ~4-5 hours
Chain 5 amino acids —
Type Growth hormone secretagogue Aryloxypropanolamine derivative (C16H21NO2)
Key Benefits
Ipamorelin
01 Optimal GH stimulation with superior bioavailability
02 Body composition improvements (lean mass, fat loss)
03 Enhanced recovery and anti-aging effects
04 Minimal side effects compared to other GHRPs
05 No significant cortisol or prolactin elevation
06 Improved sleep quality
Propranolol
01 Rapid reduction of elevated heart rate within 30-60 minutes of oral dosing
02 Effective against tachycardia from both trenbolone and clenbuterol through non-selective beta blockade
03 Well-established anxiolytic effect for performance anxiety without cognitive impairment or sedation
04 Short half-life allows flexible as-needed dosing without prolonged hemodynamic effects
05 Extensive clinical safety data spanning over 50 years of use
06 Inexpensive and widely available as a generic medication
07 Does not cause dependence or withdrawal symptoms typical of benzodiazepines
08 Effective for controlling physical anxiety symptoms (tremor, palpitations, sweating)
Dosing Protocols
Ipamorelin
200-300 mcg per injection / 1-3 times daily depending on goals (1x for longevity, 2-3x for performance)
General Health & Longevity 200mcg 1x daily before bed
Body Composition 250-300mcg 2x daily (morning, pre-workout)
Athletic Performance 200-250mcg 2-3x daily
Sleep & Recovery 200mcg 1x daily 30min before bed
Anti-Aging Protocol 200-250mcg 1-2x daily
Propranolol
10-80 mg/day / 1-3 times daily (or as needed)
Side Effects
Ipamorelin
Mild hunger increase 20-30 minutes post-injection
Slight drowsiness when taken before bed
Water retention (mild)
Propranolol
Fatigue and reduced exercise tolerance, particularly during the first week of use
Cold extremities (hands and feet) due to beta-2 blockade of peripheral vasodilation
Bradycardia (heart rate below 60 bpm), usually dose-dependent and asymptomatic
Dizziness or lightheadedness, especially when standing quickly
Gastrointestinal discomfort (nausea, diarrhea, constipation)
Contraindications
Pregnancy or breastfeeding
Active cancer or history of cancer
Severe kidney or liver disease
Asthma or severe reactive airway disease (non-selective beta blockade can trigger life-threatening bronchospasm)
Decompensated heart failure or cardiogenic shock
Sinus bradycardia (resting HR below 50 bpm) or second/third-degree heart block
Severe peripheral arterial disease or Raynaud's syndrome
Pheochromocytoma without prior alpha blockade (risk of hypertensive crisis from unopposed alpha stimulation)
