CategoryPeptidesPeptides
Standard DoseResearch indicates 10-30 mL daily via intravenous infusion for neurological indications. 5-10 mL for cognitive optimization.Research indicates 1-10 mcg/kg via subcutaneous injection or IV bolus for acute HPG axis stimulation.
TimingMorning administration preferred for cognitive effects. IV infusion over 15-20 minutes.Morning dosing preferred for testosterone optimization. Can be used acutely before sexual activity.
Cycle Duration10-20 day intensive cycles repeated every 3-6 months. Some protocols use ongoing 3x weekly maintenance.Short-term use only. Continuous kisspeptin administration may cause tachyphylaxis (desensitization) of the HPG axis.

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.

Kisspeptin-10

Peptides

Mechanism

Kisspeptin-10 is the 10-amino acid C-terminal fragment of the kisspeptin family that signals directly to GnRH neurons through the kisspeptin receptor (KISS1R/GPR54), triggering GnRH release into the portal circulation. This stimulates LH and FSH secretion from anterior pituitary gonadotrophs. In men, intravenous kisspeptin-10 produces rapid dose-dependent LH rises (4.1 to 12.4 IU/L at 1 mcg/kg within 30 minutes), increases LH pulse frequency and amplitude, and subsequently elevates testosterone through the HPG axis.

Standard Dosing

Research indicates 1-10 mcg/kg via subcutaneous injection or IV bolus for acute HPG axis stimulation.

Timing

Morning dosing preferred for testosterone optimization. Can be used acutely before sexual activity.

Cycle Duration

Short-term use only. Continuous kisspeptin administration may cause tachyphylaxis (desensitization) of the HPG axis.

Side Effects

  • Facial flushing
  • Mild nausea
  • Elevated LH/testosterone (desired effect)
  • Potential for HPG axis desensitization with prolonged use

Contraindications

  • Hormone-sensitive cancers (prostate, breast)
  • Pregnancy and breastfeeding
  • Children/adolescents (premature puberty risk)
