- Thymalin
- Thymic bioregulation, T-cell differentiation
- 5–10mg every 5–7 days
- −20°C lyophilised, 2–8°C reconstituted
- Immune senescence, tissue regeneration research
- Most reliable for thymic function studies. Established peptide sequence with decades of Soviet-era research foundation
- MK-677
- Growth hormone secretagogue (ghrelin mimetic)
- 10–25mg daily oral
- Room temperature stable (oral form)
- GH pulsatility, lean mass, bone density research
- Non-injectable convenience with consistent IGF-1 elevation in 24-month trials. Rare for oral peptide mimetics
- Cerebrolysin
- Neurotrophic peptide complex, BDNF activation
- 5–30ml IV over 10–20 sessions
- 2–8°C (aqueous solution)
- Neuroplasticity, stroke recovery, cognitive research
- Gold standard for neurotrophic peptide research. Published efficacy in 1,500+ patient trials across neurological conditions
- Dihexa
- HGF/c-Met pathway agonist, synaptogenesis
- 1–5mg daily (nanomolar potency)
- Synapse formation, cognitive enhancement research
- Seven orders of magnitude more potent than BDNF at promoting synaptogenesis. Exceptional for targeted neuroplasticity studies
- Survodutide
- Dual GLP-1/glucagon receptor agonist
- 2.4–4.8mg weekly subcutaneous
- 2–8°C reconstituted, stable 28 days
- Metabolic research, fat oxidation studies
- Phase 2 trials showed 12.8% body weight reduction at 48 weeks. Dual-agonist mechanism compounds GLP-1 satiety with glucagon thermogenesis
- Mazdutide
- GLP-1/glucagon dual agonist
- 3–6mg weekly subcutaneous
- 2–8°C reconstituted
- Metabolic pathway research, energy expenditure
- Similar dual-receptor targeting to survodutide with slightly different receptor affinity profile. Useful for comparative mechanism studies
