Hcg info needed

Hi!
I've been advised in my previous thread to start hcg from week 3 until pct for my 10 week test/ tren h cycle.
So hcg 250 iu x 2 per week for 8 week.

Now my question is... Hcg is available for IM in an ampoule.
Do we need to dilute it? Or it can be just injected in the glutes?

Totally unaware as I am doing this for the first time.
Any help would be very much appreciated.
Thanks

hcg is in powder form, So you add water to it to reconstitute it.
i would just inject it sub q with an insulin needle

I am getting hcg of minimum 2000 iu.
So how do I take it during cycle?
