A

Low-Dose Naltrexone

Pharmaceuticals

Mechanism

Transient opioid receptor blockade that may increase endogenous endorphin signaling and modulate immune tone in off-label protocols.

Contraindications

  • Concurrent opioid use
  • Use caution in active liver disease
B

Tesofensine

Pharmaceuticals

Mechanism

Tesofensine (NS2330) is a triple monoamine reuptake inhibitor with affinity for dopamine (DAT), serotonin (SERT), and norepinephrine (NET) transporters. It suppresses appetite through indirect stimulation of alpha-1 adrenoceptor and dopamine D1 receptor pathways, reflecting additive effects of increased NE and DA activity. Tesofensine is a dual-action drug with both anorexigenic properties (appetite suppression) and metabolic properties (increased energy expenditure), silencing GABAergic hypothalamic neurons in the lateral hypothalamus.

Standard Dosing

Research indicates 0.25-0.5 mg daily via oral administration.

Timing

Morning dosing only. Avoid afternoon/evening dosing due to stimulant properties and potential insomnia.

Cycle Duration

12-24 week cycles. Monitor cardiovascular parameters throughout.
