Your GHK is 100, 000 mcg right? You're diluting with technically 300 units. 100, 000/300 = 333.3 mcg/unit

2mg = 2000mcg 2000mcg/333.3 = 6units

Someone likely has a simpler way to think of it but that's how my brain does it

Stock vial: 100 mg GHK-Cu in 3 mL → 33.3 mg/mL You drew: 0.03 mL stock → 1 mg GHK-Cu You added: 0.47 mL BAC → total 0.50 mL syringe volume Now, the concentration in the syringe is: Concentration = Amount of GHK-Cu Total volume = 1 mg 0.5 mL = 2 mg/mL Concentration= Total volume Amount of GHK-Cu ​ = 0.5 mL 1 mg ​ =2 mg/mL So your syringe is 2 mg/mL, not 1 mg/mL. If you want 1 mg/mL instead, you would need to add 0.97 mL BAC to the 0.03 mL stock instead of 0.47 mL. Calculation: 1 mg ÷ 1 mg/mL = 1 mL total volume → subtract 0.03 mL stock → 0.97 mL BAC So your current setup is 2 mg/mL, which is fine for dosing 100–200 mcg per injection (just draw 0.05–0.10 mL).

That verbosity is mind numbing

It's already wrong when it says 0.03mL is 1mg

Oh wait, yeah that's correct

its definitely got the math correct lol

i've triple checked that

It's confusing to me because I don't math it that way in my head

it's just diluting the ghk with more bac to get the correct concentration from my understanding

It checks out but you want to pin 1ml of liquid for 2mg

That's a lot of liquid subcutaneous

yeah i'm starting at 1mg. is 2mg typical dose?

Yeah, I think generally people do 2-2.5mg

oh ok, i guess i should recalculate

I would just dilute with 3ml, draw 6units and then draw 6more units of water

It's so much more confusing to think in ml though because your syringe is in units unless it's not an insulin needle
