1 dosing mention · 0 vendor recs · 8 PubMed papers
Retatrutide
Triple agonist of GLP-1, GIP, and glucagon receptors used for appetite suppression and fat loss, but can blunt dopamine/serotonin reward signaling.

A methylxanthine caffeine analog that increases dopamine release, providing motivated energy in addition to caffeine-like stimulation.
1 dosing mention · 2 vendor recs · 8 PubMed papers
Tesofensine
Triple monoamine reuptake inhibitor (NE/DA/5-HT); intense stimulant-like effects and appetite suppression.
3 dosing mentions · 0 vendor recs · 8 PubMed papers
