- This table compares foundational protocol structures for different research goals when building a DIY peptide protocol from scratch.
- Growth Hormone Modulation
- CJC-1295/Ipamorelin, MK-677
- Ghrelin receptor agonism + GH secretagogue
- Daily (evening) for GHS; oral daily for MK-677
- 12–16 weeks
- Strongest evidence base for body composition research; well-tolerated with predictable dose-response curve
- Cognitive/Nootropic Stack
- Cerebrolysin, Dihexa, P21
- BDNF upregulation, NMDA modulation, synaptic plasticity
- 5 days per week (weekday dosing)
- 8–12 weeks
- Highly individual response variance; P21 shows clearest subjective effects within 2–4 weeks
- Metabolic/Fat Loss Protocol
- Tesofensine, Survodutide, Lipo-C
- Monoamine reuptake inhibition, GLP-1/glucagon agonism, lipotropic support
- Weekly for GLP-1 agonists; daily for Tesofensine
- 16–24 weeks
- Survodutide dual-agonist mechanism provides superior weight reduction vs single-pathway agents; requires dietary structure
- Immune Support/Longevity
- Thymalin, KPV
- Thymus peptide bioregulation, anti-inflammatory signalling
- 10–20 days on, 2–3 months off (pulsed)
- Intermittent cycles
- Thymalin shows strongest effects in immune-senescent populations; KPV effective for gut inflammation models
