How do I read a simple peptide dosing protocol for a first timer?

Question

Hey mate, I just got my first vial of something like BPC-157 5mg powder and I’m staring at a protocol online that says “250mcg subQ every day”. I’m totally lost on how to turn that into something I can actually measure with an insulin syringe. For me the maths feels tricky – if I reconstitute with 1ml of bacteriostatic water does that give me 5mg/ml? 05ml which is 5 units on a 100unit syringe? Ngl I’m second guessing myself because I don’t want to mess up the dose or hit a vein by accident. Anyone else remember their first time trying to read a protocol like this? What’s the easiest way to double check the volume before you inject? Also, should I be pinching the skin or going straight in? Any tips on keeping things clean and simple would be really appreciated.

For me the easiest way is to think in milligrams first. If you dissolve the 5 mg vial in 1 ml bacteriostatic water you get 5 mg per ml, which is 5000 mcg/ml. 05 ml, and on a standard U‑100 insulin syringe that lines up with the 5‑unit mark. I usually double‑check by drawing the water into the syringe, pushing it out to see the 5‑unit line, then drawing back the same amount from the vial.

Tbh that matches what I did, but I always pull back a bit to check for bubbles before injecting, just in case.

Ngl I was so worried about the math that I completely forgot about air bubbles. Thanks for the tip, I'll definitely make sure to pull back on the plunger to check the syringe before I go in. Do you usually find it easier to do that after you've already drawn the liquid up, or do you try to avoid getting them in the first place?

Ngl that makes me feel a bit better about my maths. I was definitely panicking about the 5000mcg per ml part. Your method of drawing the water into the syringe first to check the 5-unit line sounds spot on for making sure I dont overdo it. Quick one though, when you are drawing back from the vial, do you find it easier to hold the vial upright or do you tilt it to get the air out properly?
