···11+22+There are several routes of taking HRT and the main forms are: pills, gels, patches and injections. There are less common forms too that are mainly used in the DIY scene such as Transdermal Estradiol Spray and Sublingual Estradiol Oil Drops.
33+44+diyhrt.info lists a general price range for the more common methods but that is very US targeted and obviously differs for DIY and different health cares so here I will go over a few specific forms, their common dosages/concentrations and any other relevant information on those methods.
55+66+## Pills
77+88+Pills come in two common formulations Estradiol Valerate and Estradiol Hemihydrate.
99+1010+the most common concentrations are 1mg and 2mg pills.
1111+1212+Generally in pill form the bioavailability is low so right off the bat I recommend taking them the sublingual route(placing the pill under your tongue and letting it slowly dissolve).
1313+1414+Sublingual is around 1.5x more effective at absorbing oestrogen compared to the oral route.[^1]
