NAD+ is available as a primary ingredient in some supplements, but the current understanding of NAD+ metabolism is that its bioavailability is severely limited compared to a pair of its precursors: NMN and NR.6 By using NAD+ precursors instead of NAD+ itself, you can end up with more NAD+ available for your body to utilize
Standard research protocol: BPC-157: 250500mcg per dose TB500: 250500mcg per dose Frequency: once or twice daily Duration: 46 weeks for acute injuries, 812 weeks for chronic conditions Route: subcutaneous or intramuscular injection Acute injury protocol: Higher frequency (twice daily) for the first 12 weeks Localized injections near the injury site are an option Transition to once daily after the early healing phase Total duration: 46 weeks is often enough Chronic condition protocol: Once daily is often enough Systemic (abdominal) injections are common Extended duration (812 weeks) may be needed Cycling on and off is an option for long-term use Post-surgical recovery protocol: Begin immediately after surgery if possible, under medically supervised conditions Twice daily for the first week Once daily for the following 35 weeks Localized injections near the surgical site are an option Dosage Calculator Considerations When calculating precise doses, researchers should consider: Concentration: Standard blend: 10mg BPC-157 + 10mg TB500 per vial Reconstitution volume affects concentration Use PrymaLabs Peptide Calculator for exact figures Example calculation: reconstituting a 10mg+10mg vial with 2mL sterile water: Final concentration: 5mg/mL of each peptide For a 250mcg dose of each: 0.05mL (5 units on an insulin syringe) For a 500mcg dose of each: 0.1mL (10 units on an insulin syringe) Body weight factors: Some research uses weight-based dosing Typical range: 24mcg/kg per peptide Most research uses fixed doses (250500mcg) regardless of weight Adjust based on injury severity and response Reconstitution Protocol Proper reconstitution is essential for preserving peptide stability and ensuring accurate dosing
