Does anyone here shoot their hCG subcutaneously?

I haven't been able to find the information leaflet for Pregnyl on the web but I've found multiple medical sites that mention you can inject it either intramuscularly or subcutaneously.

Would the absorption be less if you take it subcutaneously?

If I get Pregnyl 5000 IU, and if I add just 2.5cc of water to it, then I'll have a concentration of 2000 IU per 1cc.

So that means, if I wanted to shoot 200 IU at a time, that I'd only need to inject 0.1cc at a time, which would be the 10 mark on an insulin syringe. This would be ideal for subcutaneous injection, exactly like shooting insulin.

I would shoot 200 IU every other day (which works out at 700 IU per week).

Or is there a reason to favour intramuscular injection?

For my next cycle I want to keep my intramuscular injections to a minimum, which is why I'm looking into shooting hCG subcutaneously if possible.

By the way, one other thing:
I've done maybe 2 or 3 subcutaneous injections before, and each time it stung like hell! Do all subcutaneous injections sting? Or maybe it was just the stuff I was injecting (Melanotan II reconstituted with bacteriostatic water).
