Keep the vial in the main refrigerator compartment, not the door where temperature fluctuates
A reasonable candidate is someone who: Is already following a structured, clinician-supervised nutrition and activity plan Has a documented B12 deficiency or a condition that impairs B12 absorption Cannot tolerate GLP-1 medications, or is not a candidate for them Declines prescription pharmacotherapy and wants a non-stimulant, non-surgical adjunct Understands because the clinician has said so plainly that the injection is a supporting player A poor candidate is someone who wants the shot instead of the program

The bioavailability problem Absorption comparison: Injection: 80-100% bioavailability (nearly all absorbed) Nasal spray: 30-70% bioavailability (varies by peptide) Oral: 0-5% bioavailability (most peptides destroyed) Why nasal lower than injection: Must penetrate nasal mucosa (barrier) Some drips down throat (swallowed = lost) Variable absorption efficiency Technique-dependent Individual variation high What this means: You need MORE peptide via nasal spray Typically 2-3x higher dose than injection Example: 1mg injection = 2-3mg nasal Increases cost significantly But still cheaper/easier than injection for some Conversion guidelines by peptide PT-141: Injection: 1.5-2mg typical dose Nasal equivalent: 3-5mg Conversion ratio: 2-3x Semax: Designed for nasal use (no conversion needed) Standard nasal dose: 200-600mcg per spray 2-3 sprays per nostril typical Follow product guidelines BPC-157 (if attempting nasal): Injection: 250-500mcg Nasal (estimated): 750-1500mcg But: Injection or oral likely better Nasal BPC-157 not well-studied General conversion approach: Start with 2-3x injection dose Assess results after 2-3 uses Increase by 25-50% if weak effects Find minimum effective nasal dose Individual variation significant Cost implications: Using 2-3x more peptide = 2-3x cost Nasal spray more expensive per dose Trade-off: Convenience vs cost Worth it for needle-phobic Not worth it if injections acceptable Use peptide cost calculator to compare routes

The ribT function remained unknown until recent research showed that its enzyme is a member of GCN5-related N-acetyltransferase, which transfers the acetyl group from acetyl-CoA to a variety of substrates (Srivastava et al., 2018
