When you're investigating something as delicate as meniscus regeneration, you need to be absolutely certain that the molecule you're studying is precisely the molecule it's supposed to be
On a U-100 insulin syringe (where 100 units equals 1 mL), the math comes out to clean whole units: 10 mg sermorelin vial reconstituted with 3 mL BAC water (3,333 mcg/mL) Target dose 100 mcg Draw volume 0.03 mL Units (U-100) 3 units Target dose 200 mcg Draw volume 0.06 mL Units (U-100) 6 units Target dose 300 mcg Draw volume 0.09 mL Units (U-100) 9 units Target dose 400 mcg Draw volume 0.12 mL Units (U-100) 12 units Target dose 500 mcg Draw volume 0.15 mL Units (U-100) 15 units Round to the nearest unit if your syringe does not show half-unit marks
