Not necessarily endorsing this outfit, using such to make people aware of marketing and costs envolved, could be critical to your wallet if paying it all yourself and makes you aware of the additional costs here in USA for dispensing such in an office setting and mark up, marketing and such. Some people do handle their own Lupron or Zoladex and other such things that normally we would do only in a docs office, it is an option, I am not endorsing anything, we have options. (

Estradiol patches Vivelle .025/24hr. (40)ct.= $150 (doseages worn varies)
Climara patch (generic) 50mcg (8 patches)= $30 " " "
Ketoconazole (Nizoral generic)- 200mg (100)ct.= $129 (cheap)
Zometa (Novartis) I.V. 4mg/5ml 3x5ml= $1395 (generic Zolendronic=$1349)
Leukine solution 500mcg/ml 10x1ml= $3435 (costly but much cheaper than USA)
Alot of variation out there even domestically one can shop around if needed. The cancer world in general there are such things as pills that cost $200+ a day or drug protocols for a single agent that could cost $10,000 per month (these are in other types of cancers for just to mention such). 
Not to mention these are usually control drugs and not necessarily at all of a curing nature. We have choices, options and ways and means I suppose that is the good news.
In the above if you did your own Lupron injection it would cost under $900 or less, per YEAR- your local docs office under their administering probably around $10,000-15,000 per year- (I wish I could make a small profit to stay in business...LOL)
