I figured this out with melanotan but it's been awhile so back to the basics. I have a 1mL slin and 5mg of BPC-157 I can't remember how much to draw to reconstitute to make this easy

If you add 1ml of water then every 10 mark on the syringe will be 500mcg, if you add 2ml of water then every 10 mark will be 250mcg so that's probably what I would do. And just to show the math for those who want it broken down... 5,000mcg(5mg) divided by 100 units (1ml)= 50mcg per unit, so every 10 units(0.10ml) is 500mcg 5,000mcg(5mg) divided by 200 units (2ml)= 25mcg per unit, so every 10 units(0.10ml) is 250mcg
