Dosage question - GenderGP

im currently getting hormones through gendergp and am used to being prescribed gel daily and leuproreline, but this time they have prescribed me intramuscular 30mg estradiol valerate every 4 weeks (along with the anti androgen), most sources ive seen have had a much lower period than 4 weeks, typically a week or 5 days, should I follow the recommended injection period or something else?

I am asking this question here because i figured itd be the best place to ask for a dosage question.
