The recommended dosages I'm seeing vary quite a lot. How dependent is dose on, for example. I was planning on a 8mg loading dose followed by weekly injections of 5 mg to start but my supplier recommends 7.5mg per week which seems high.

I'm on the larger side so I'd probably need a slightly higher dose, but does anyone know a website where I can get pharmacokinetic calculations and the like? It seems like weight and body fat percentage would have an effect on dose but I haven't seen information on that.

I don't mind taking a higher dose, but I'd like to make it last if possible.

4mg-5mg weekly is very standard, but some do need a bit more to properly suppress T. 7.5 sounds like a way too high number for no real reason. Some people may need that, but the vast majority won't. I recommend sticking to your plan of 5 (or even reducing to 4) and then adjusting depending on what your blood tests show.

I might be wrong, but your first guess was to me the best approach.

As far as I know, from a french trans national association. weight and body fat pourcentage doesn't play a role.

I use 5mg / week and I'm around 200pg/ml for estradiol. (Which is supposed to be between 100-200 if I'm right)

Testosterone ~1nmol/L (or 29ng/DL) I think my testosterone could be lower (I think it's supposed to go down to 0.5nmol/L), but the estradiol is where it's supposed to be for me. So I can go slightly higher to see if it suppress more T ( but I shouldn't go too high on E too.)

You mileage may vary of course. Please folks correct me if I'm wrong. I don't want to give false information.

Weight

Tap for spoilerOh, I'm still obese if that helps for the doubt about the weight. 108 kg ( from 125kg 5 month ago to give you context)
