  • The following table synthesizes published research observations and protocol reports to compare Pe-22-28 side effects against key parameters that determine tolerability in peptide research.
  • Injection site erythema
  • 8–12%
  • Mild
  • 20–60 minutes
  • Use bacteriostatic water reconstitution, ensure pH 6.5–7.5, inject slowly over 10 seconds
  • Most common observation; correlates with purity and technique rather than peptide sequence
  • Transient fatigue
  • <10%
  • 2–4 hours post-dose
  • Administer in morning, start at 100 mcg and titrate upward over 7–10 days
  • Dose-dependent; resolves with timing adjustment in 90% of cases
  • Headache
  • <5%
  • 1–3 hours
  • Slow dose escalation, avoid starting above 150 mcg, ensure adequate hydration
  • Primarily observed in rapid escalation protocols; rare at steady-state
  • Cardiovascular effects
  • 0%
  • None
  • N/A
  • None required
  • Zero reported cases of hypertension, fluid retention, or electrolyte disturbance at research doses
  • Cognitive overstimulation
  • No anxiogenic or stimulant effects observed, unlike Semax or racetam compounds
  • Serious adverse events
  • Follow standard peptide handling protocols
  • No discontinuations due to side effects in any published protocol
