Quote from: Dani on May 10, 2017, 10:09:29 AMEstradiol is bio-identical and the uncoated tablets dissolve within a few minutes after they are placed under the tongue. The most common makers of uncoated estradiol are Mylan, Teva and Watson. All 3 makers produce a good product. I know, since I am a Pharmacist.
All tablets containing MICRONIZED estradiol can be taken sublingually. If the outer part of the pill can dissolve, then it can be taken sublingually.
QuoteTaking estradiol sublingual works just like injectable as the hormone does not go through your liver right away. The estradiol goes into the general blood circulation and from there goes to the entire body, where it does a body good.
I think that taken sublingually, inevitably, some will be swallowed and enter the digestive tract, then liver. This would seem to explain why even sublingually, estrone eventually surpass estradiol levels.
QuoteInjectable estradiol is in a oil vehicle and will last 14 days, with relatively steady blood levels.
That depends on the form of estrogen. Estradiol valerate will usually be good for at most 7-10 days, before causing PMS in the vast majority of women. In some, levels already significantly decline by days 5-6. Levels tend to not be that stable as they peak and quickly fall relative to other forms (i.e. cypionate, enanthate, undecylate/undecanoate or polyestradiol phosphate). From day 3 to day 5, my levels went from 2,500 to 1,300 pg/ml! Estradiol cypionate, on the other hand, yields more constant levels, peak levels are reached more slowly and it can be good for longer, up to 10-14 days.
QuoteWith sublingual, you get a peak level within the hour and you will have high levels for about 12 more hours
Not quite. Levels peak and fall rapidly. One study found levels to be at approximately:
1 hour: 450 pg/ml
2 hours: 200 pg/ml
3 hours: 115 pg/ml
4 hours: 80 pg/ml
12 hours: 40 pg/ml
In just 3 hours, levels fell by more than 500%. With sublingual, don't expect steady high levels. There is a rapid drop and this is why blood tests for estradiol are so inaccurate in this context.
In my own personal experience, I had the same results (i.e. mental/physical) on sublingual vs oral.
QuoteIt is just much safer if you avoid the first pass through the liver. So for safety sake, injectable, sublingual or topical patches are all just fine.
Bio-identical estradiol, IMO, based on several studies, seems quite safe so that sublingually, where some of it is inevitably swallowed, doesn't make a significant difference in terms of health risks. All other non-oral route are only *slightly* safer, I think.
QuoteI do not like needles and I prefer to take my estradiol sublingual.
I found sublingual quite inconvenient, having to wait for it to dissolve whereas with needles, I inject only once every few days and it's done. So easy and practical, for me. I had to overcome my fear of needles and it was totally worth it.
Quote from: LShipley on May 10, 2017, 10:35:41 AMIm surprised there isnt some sort of implant for longer periods of time. Or are there?
In some parts of the world, there are.

For quite some time, too.

I've been on transition dosages of both. They both have their pluses and minuses. As far as being even tempered and more able to cope on a daily basis? I'll take the pills. As far as physical feminization in a hurry? I'll take injections
I actually find that I'm calmer and more even tempered on injections vs sublingual/oral. Breast growth was better for me on oral/sublingual, by FAR, despite estradiol levels being much higher on injectables.
QuoteRegarding the possibility of contracting Prolactinoma? I'd take pills to lessen that chance of occuring.
Prolactinomas are quite rare among transwomen, only 8 reported so far. None on injections of estradiol taken alone, without any other form of non bio-identical estrogen or non bio-identical progestogen. Most prolactinomas were associated with the use of oral estrogen, only conjugated equine estrogens and ethinyl estradiol, usually with cyproterone acetate. Studies therefore don't substantiate your fear of getting a prolactinoma with E injections. One study in particular found no one developed a prolactinoma despite very high doses of estradiol valerate by injections. The same findings were shown in other studies where men and ciswomen were treated with high doses of injectable E.
QuoteAs far as DVT possibility and potential organ damage? bring on those injections.
The risk of DVT appears to be infinitesimally small with oral bio-identical estradiol as compared to other forms of estrogen and if it occurs, there are always other factors present like smoking, cardiovascular predisposition, diabetes, old age, immobilization due to surgery, pre-existing clotting disorders/genetic mutation, obesity.
Organ damage, as far as I know, none reported with bio-estradiol in the scientific literature. And for sure, none in transwomen.
Quote from: EmmaLoo on May 10, 2017, 03:01:38 PMIn the beginning, I was taught to do it in the thigh muscle. Eventually, I switched to the butt cheek.
Injecting in the buttocks for 3 years, with not much pain, if any during the process of injecting. No pain afterwards or VERY, VERY rare.
QuoteThe other thing you might look at are the needles you are using to draw and inject with. That can make a big diffefence as well.
The higher the Gauge of the needle, the thinner and the less painful it is but the longer it takes to inject as the solution is oily and thick. I inject with a 22 gauge but 23-25 seems to work best for some.
Quote from: rmaddy on May 10, 2017, 03:19:40 PMI generally use a 23 gauge 1" needle.
In thigh, this might be fine but buttocks, this might be too short, end up in subcutaneous tissue and leak as it did for me. My butt is fatty.

QuoteIf you want, you can purchase larger gauge needles to draw out of the vial, but I found that this chewed up the rubber stopper on the vial after awhile.
+ 1. i drew with an 18 gauge. So chewed up, it was leaking.

QuoteI decided to draw it up with the 23.Works for me.
23 gauge takes too long for me. I personally prefer 21.
