  • Tirzepatide
  • Dual GLP-1/GIP agonist
  • GLP-1R, GIPR
  • ~5 days
  • Metabolic research, insulin sensitivity studies
  • Strongest metabolic efficacy data among dual agonists; 20.9% mean weight reduction in SURMOUNT-1 trial
  • Survodutide
  • Dual GLP-1/glucagon agonist
  • GLP-1R, GCGR
  • ~7 days
  • Thermogenesis research, hepatic metabolism
  • Additive fat oxidation beyond GLP-1 monotherapy; requires careful titration due to glucagon effects
  • Mazdutide
  • ~6 days
  • Energy expenditure studies
  • Higher glucagon affinity than survodutide; stronger thermogenic signal but increased GI side effects
  • Cerebrolysin
  • Neurotrophic peptide mixture
  • TrkB, BDNF pathways
  • 2–4 hours
  • Neuroprotection, synaptic plasticity
  • Mixed peptide preparation; broader mechanism but less receptor specificity than single compounds
  • Dihexa
  • BDNF mimetic
  • TrkB
  • 4–6 hours
  • Cognitive enhancement, leptin sensitivity
  • Higher oral bioavailability than cerebrolysin; cleaner BDNF pathway activation
  • MK-677
  • Ghrelin receptor agonist
  • GHSR1a
  • 24 hours
  • GH pulse research, IGF-1 studies
  • Maintains efficacy across months; preserves natural GH rhythm unlike exogenous GH
  • Tesofensine
  • Triple monoamine reuptake inhibitor
  • DAT, NET, SERT
  • ~8 days
  • Appetite regulation, noradrenergic research
  • Potent appetite suppression via norepinephrine/dopamine; not a peptide but often grouped with metabolic agents
  • Thymalin
  • Thymus-derived peptide
  • Immune cell receptors
  • 6–12 hours
  • Immune modulation, T-cell function
  • Primary immune application; metabolic effects secondary to improved immune-endocrine crosstalk
