Energy is a vaguer goal than weight or recovery, and the peptides linked to it tend to act on metabolism or the growth-hormone axis rather than being stimulants. As with most of these categories, the human evidence for a felt energy benefit is limited.
Reviewed for accuracy · Last reviewed July 7, 2026The compounds below are the ones most discussed for energy. Each links to its full profile, where the dosing, side effects, and sources live. They are ordered roughly by how much human evidence sits behind them, not by a claim that any one works.
None of these is a stimulant, and none has strong human evidence for improving day-to-day energy as such. MOTS-c is the one with the most direct mechanistic link, through mitochondrial and metabolic pathways, but its human data is sparse and mostly observational.
The growth-hormone secretagogues affect sleep architecture and metabolism, which people sometimes experience as improved energy, but that is indirect and not well quantified in trials. Apart from tesamorelin, these are research-only compounds.
