  • Growth Hormone Secretagogues (MK 677, GHRP-2)
  • 4–6 hours
  • 90 minutes post-IV
  • Avoid dextrose solutions
  • Short half-life demands maximum absorption window. Dextrose-induced hyperglycaemia reduces GH pulse amplitude
  • Thymic Peptides (Thymalin, thymosin)
  • 2–4 hours
  • Avoid high-dose vitamin C
  • Glycation-sensitive due to multiple lysine residues. Requires dextrose-free IV and extended spacing
  • Nootropic Peptides (Cerebrolysin, Dihexa)
  • 3–8 hours
  • 60–90 minutes post-IV
  • Normal saline preferred
  • Methionine-rich peptides vulnerable to ascorbic acid oxidation. Avoid Myers' Cocktail formulations
  • GLP-1 Agonists (semaglutide, tirzepatide)
  • 5–7 days
  • 45–60 minutes post-IV
  • No restrictions
  • Extended half-life tolerates shorter spacing. Steady-state levels buffer transient dilution effects
  • Short-Chain Peptides (KPV, BPC-157)
  • 1–3 hours
  • Avoid dextrose and ascorbic acid
  • Minimal circulation time requires optimal absorption conditions. Any interference significantly reduces bioavailability
