Optimized volume/price ratio, extended autonomy (several weeks at typical 250-500 mcg dose), final concentration adjustable to protocol (5 mg/ml with 2 ml bacteriostatic, or 2.5 mg/ml with 4 ml for finer dosing)
The evidence: There are decades' worth of scientific research into the role of NAD+ in the body
Safety Considerations Peptides are generally well-tolerated, but risks include: A longevity-trained physician must supervise peptide therapy (Smith et al., 2020)
Numerous peptides demonstrate good safety profiles in short-term studies, but long-term data are limited
These are considered two of the bioactive forms of B12, and they work well for many
Research-grade peptides purchased online are not manufactured to the same standards
