| Category | Peptides | Peptides |
| Standard Dose | Research 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. |
| Timing | Morning 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 Duration | 10-20 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 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.

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.
Research indicates 1-10 mcg/kg via subcutaneous injection or IV bolus for acute HPG axis stimulation.
Morning dosing preferred for testosterone optimization. Can be used acutely before sexual activity.
Short-term use only. Continuous kisspeptin administration may cause tachyphylaxis (desensitization) of the HPG axis.
