- The table below compares the dominant peptides across metabolic, nootropic, and regenerative research categories based on October 2026 order volume, mechanism, administration route, and typical research applications.
- Tirzepatide
- Dual GIP/GLP-1 receptor agonist
- ~5 days / weekly
- Subcutaneous
- Metabolic syndrome models, NAFLD research, insulin sensitivity studies
- Clearest dose-response curve in the GLP-1 category. Weekly dosing reduces protocol complexity
- Retatrutide
- Triple GLP-1/GIP/glucagon agonist
- ~6 days / weekly
- Severe obesity models, hepatic steatosis, multi-pathway metabolic research
- Highest magnitude weight reduction outcomes in published trials. Requires careful titration
- Dihexa
- HGF receptor activation (neurogenic)
- ~2 hours / daily
- Oral
- LTP enhancement, hippocampal neurogenesis, cognitive decline models
- Seven-million-fold greater neurogenic potency than BDNF. Oral bioavailability eliminates injection
- Cerebrolysin
- Neurotrophic factor complex (NGF/BDNF-like)
- Variable / protocol-dependent
- Intramuscular
- Stroke recovery, neurodegenerative models, excitotoxicity protection
- Longest track record in neuroprotection research. Requires reconstitution and cold storage
- FOXO4-DRI
- FOXO4-p53 binding disruption (senolytic)
- ~4 hours / multi-day cycles
- Senescent cell clearance, aging models, tissue regeneration
- Most selective senolytic mechanism available. Targets only FOXO4-p53 interaction
- BPC-157
- VEGF upregulation, collagen synthesis
- ~4 hours / daily or BID
- Subcutaneous or oral
- Gastric ulcer healing, tendon repair, ligament recovery, gut-brain axis
- Most-ordered regenerative peptide. Stable across extreme pH ranges
