- Intramuscular (IM). Deltoid or Gluteus
- 95–100%
- Moderate. Requires 1.5-inch needle, correct angle
- Peak plasma: 2–3 hours
- Gold standard for Cerebrolysin. Full peptide bioavailability, consistent absorption kinetics. Tech workers can self-administer deltoid injections with proper technique training.
- Subcutaneous (SubQ). Abdomen or Thigh
- 70–85%
- Easy. 0.5-inch needle, 45° angle
- Peak plasma: 4–6 hours
- Not recommended for Cerebrolysin specifically. Peptide molecular weight (>5 kDa fraction) absorbs poorly through subcutaneous tissue. Lower bioavailability means subtherapeutic BDNF upregulation.
- Intravenous (IV). Clinical Setting Only
- 100%
- Requires medical professional
- Immediate plasma peak
- Highest bioavailability but impractical for 20-day protocols. Used in clinical stroke recovery settings, not cognitive enhancement. Risk of infection if sterility protocols aren't hospital-grade.
