- Active Sequence
- GLU-ASP-ARG (100% defined)
- GLU-ASP-ARG (~60–75% of peptide content)
- Identical active molecule. Difference is purity
- Production Method
- Solid-phase peptide synthesis (SPPS)
- Enzymatic digestion of bovine pineal tissue
- SPPS eliminates batch-to-batch variability
- Purity
- 98–99.5% via HPLC
- 85–92% (co-extracts include other peptides/lipids)
- Higher purity reduces immune response risk
- BDNF Upregulation
- +47% in hippocampal tissue (72-hour admin)
- +44% in hippocampal tissue (72-hour admin)
- Statistically equivalent neuroprotective effect
- Regulatory Status
- Synthetic compound. No TSE restrictions
- Animal-derived. Subject to TSE import controls
- Synthetic avoids regulatory complexity in EU/Canada
- Cost per mg Active
- $0.80–$1.50/mg (bulk synthesis)
- $2.20–$3.50/mg EDR equivalent (70% content)
- Synthetic is 40–60% more cost-effective
