These generally show continued safety, but definitive long-term studies don't exist
Standard reconstitution (most common) Add 2ml of bacteriostatic water to 5mg vial This creates: 2,500mcg per ml (2.5mcg per unit on insulin syringe) Easy math : 250mcg dose = 0.10ml = 10 units on syringe 350mcg dose = 0.14ml = 14 units 500mcg dose = 0.20ml = 20 units Most people prefer this concentration for easy dosing
Typically 12mL per 210mg peptide vial depending on desired concentration for the research protocol
