Key Benefits
Melanotan II
01 Rapid tanning without UV exposure
02 Enhanced sexual function and libido
03 Appetite suppression
04 Improved mood via melanocortin activation
05 Photoprotection through increased melanin
Propranolol
01 Rapid reduction of elevated heart rate within 30-60 minutes of oral dosing

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)
