New to peptides – how do I measure a 5mg vial for subcutaneous injection?

Posted by fasted_scientist in Beginner Questions - 3 points, 0 comments.

Hey folks, just got my first vial of BPC-157 labelled 5mg and I’m a bit stuck on the maths. I’ve got bacteriostatic water and a 1ml insulin syringe (the kind with 100 unit markings). If I want to dose around 250mcg per shot, how much do I actually draw up?

I’ve seen people talk about “reconstituting with 1ml water gives 5mg/ml” but then the numbers get confusing when you go micrograms. Ngl I’m overthinking it because I don’t want to mess up the dose on my first try. I’m used to drawing up meds in ICU but peptides feel different with all the mcg talk.

Could someone walk me through the calculation step by step, or point me to a simple guide that’s actually for beginners? Also, should I be pinching the skin or going straight in with the needle?
