Don’t judge please, asking for advice

4 weeks ago I was a first time user.

Bought test 300 and didn’t realise it was 300mg per 1ml.

Long story short I’ve been doing 1200mg every 8 days by doing 200mg every 4.

Is this the reason my ass is hurting so bad?

My plan is to drop down to 1ml per week for now which is 600mg a week?

Thoughts? Please be nice
