CategoryPeptidesPeptides
Standard DoseResearch indicates 10-30 mL daily via intravenous infusion for neurological indications. 5-10 mL for cognitive optimization.Research indicates 2 mg administered once weekly via subcutaneous injection.
TimingMorning administration preferred for cognitive effects. IV infusion over 15-20 minutes.Evening administration preferred (aligns with natural GH pulsatility). Inject on an empty stomach — food (especially carbohydrates) blunts GH release.

Cerebrolysin

Peptides

Mechanism

Cerebrolysin is a porcine brain-derived peptide preparation containing a standardized mixture of low-molecular-weight neuropeptides (<10 kDa) and free amino acids obtained through enzymatic proteolysis. It exerts multimodal neurotrophic effects by simultaneously upregulating VEGF, BDNF, IGF-1, and NGF while downregulating TNF-alpha. Cerebrolysin increases furin protease concentration, which promotes pro-NGF to mature NGF conversion. It activates TrkB receptor signaling (BDNF/TrkB/CREB pathway), inhibits neuronal apoptosis, reduces microglial activation, and promotes neurogenesis.

Standard Dosing

Research indicates 10-30 mL daily via intravenous infusion for neurological indications. 5-10 mL for cognitive optimization.

Mechanism

CJC-1295 with DAC (Drug Affinity Complex) is a synthetic 30-amino acid GHRH analog with four amino acid substitutions rendering it resistant to DPP-IV proteolytic inactivation. The DAC moiety covalently binds to endogenous serum albumin via a disulfide bond after injection, extending half-life to 5.8-8.1 days. It stimulates pulsatile GH release from anterior pituitary somatotrophs through GHRH receptor activation, producing dose-dependent 2-10 fold increases in plasma GH for 6+ days and 1.5-3 fold IGF-1 elevations for 9-11 days per injection.

Standard Dosing

Research indicates 2 mg administered once weekly via subcutaneous injection.

Timing

Evening administration preferred (aligns with natural GH pulsatility). Inject on an empty stomach — food (especially carbohydrates) blunts GH release.

Cycle Duration

12-24 week cycles with 4-8 week breaks between cycles.

Side Effects

  • Water retention
  • Tingling/numbness in extremities
  • Joint pain
  • Increased hunger
  • Injection site reactions
  • Potential insulin resistance with prolonged use

Contraindications

  • Active cancer or history of cancer
  • Diabetic retinopathy
  • Pregnancy and breastfeeding
  • Intracranial hypertension
