- Growth Hormone Receptor Upregulation
- 48–72 hours
- 4–7 days
- No. Single dose sufficient
- JAK2-STAT5 transcriptional activation
- Systemic (liver, muscle, bone)
- VEGF-Mediated Angiogenesis
- 72–96 hours
- 7–14 days
- No. Cascade self-sustaining once initiated
- HIF-1α stabilization → VEGF transcription
- Systemic (targets hypoxic tissues selectively)
- Nitric Oxide Pathway Modulation
- 24–48 hours
- 3–5 days
- Partial. Effects diminish without re-dosing
- eNOS dimer stabilization / iNOS suppression
- Both (systemic vascular tone + local inflammation control)
- FAK-Paxillin Pathway Activation
- 12–24 hours
- 2–4 days
- Yes. Requires sustained peptide presence
- Focal adhesion kinase phosphorylation cascade
- Local (injection site + adjacent tissues)
- Fibroblast Growth Factor Upregulation
- 5–10 days
- No. Transcriptional change persists
- bFGF receptor activation → ERK1/2 signaling
- Systemic (connective tissues, epithelial layers)
