| Standard Dose | Research indicates 10-30 mL daily via intravenous infusion for neurological indications. 5-10 mL for cognitive optimization. | Research indicates 250-500 mcg daily via subcutaneous injection during loading, reducing to 250 mcg 2-3 times weekly for maintenance. |
| Timing | Morning administration preferred for cognitive effects. IV infusion over 15-20 minutes. | Administer 4-6 hours before UV exposure for optimal tanning synergy. Can be taken at any time of day. |
| Cycle Duration | 10-20 day intensive cycles repeated every 3-6 months. Some protocols use ongoing 3x weekly maintenance. | Loading phase 1-2 weeks, then maintenance as long as desired. Pigmentation fades gradually upon discontinuation. |

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.

Melanotan II is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone (alpha-MSH) that non-selectively agonizes melanocortin receptors MC1, MC3, MC4, and MC5. MC1R activation stimulates eumelanin synthesis through tyrosinase upregulation, producing tanning. MC3R activation in the CNS increases libido and produces erectile responses. MC4R activation suppresses appetite. The cyclic structure provides enhanced in vivo stability (half-life 1-2 hours) and increased blood-brain barrier permeability compared to linear alpha-MSH.
Research indicates 250-500 mcg daily via subcutaneous injection during loading, reducing to 250 mcg 2-3 times weekly for maintenance.
Administer 4-6 hours before UV exposure for optimal tanning synergy. Can be taken at any time of day.
