I've got just under 2 months till I go and see my endo for my HRT top up.

Low dose HRT varies greatly, but I'm trying to work out a few things.

For those on low dose MTF HRT:
1.  How long have you been on it?
2.  What meds and mode of delivery?  (No dosages please)
3.  If known, what are your serum levels of E & T?
4.  Roughly how much breast development have you had?

I'm attempting to get a very rough and unscientific handle of where people are at.  It's also going to partly influence my decision at my next endo appointment.  Basing my decision in anecdotal reports is not my favoured way of making decisions, but it may give a point of reference.

Thank you to anyone who replies in advance!

To be fair, my answers:

1.  Close to two and half years.
2.  Progynova pellet, oral spiro.
3.  Last count 490 E 0.6 T
4.  Could definitely fill out a 14A cup, halfway onto a B.

As an aside, someone mentioned I look andro and could male fail if I actually tried.

Looking forward to any more replies. Thanks for all your threads non-binary HRT threads.

On a phone here goes
Start up Spiro,finesteride,low dose oral estrodiol  50 to 75

Now injecting and over 300

Crashing was a pain on orals.

Your levels are full mtf imo

36a plus.  Full levels 3 months hrt 16 months.

Spiro well over a year ago, I don't know the timeline...
E patch almost as long, but I vary the use of it to suit my moods.
The Spiro has been constant in use, but originally upped levels to max for awhile, then backed down.
It's now as low as it can be, yet I still benefit from the 'quiet' from dysphoria.
The patch is smooth, but there are times that it has been necessary to back off for periods of time.
Totally low dose, but have played around with much higher doses, it's fun, but doesn't accomplish much in the way of dysphoria.
Some redistributing of fat, not much to speak of for boobs, but I suppose they are growing somewhat.
Still less than most 'moobs' for my age group.
Loss of body hair is the most pronounced, and that's something that absolutely grosses me out, excessive body hair.
So I'm pretty happy that there's less, but none would be better.
Have no idea what the levels are, it seems to be a mute point as it works the way I want it to.
Ativan

I was told recently that I am not actually on transitioning dose, but dunno if it counts as a low dose either. I was on starting dose of oral E and spiro for 6 months, then kinda medium dose for the next 9 months. Now, 15 months in total. About 5 months was taking bioidentical progesterone.
In March, E was 47.3 pg/ml, T - 0.41 mg/ml.
I am somewhere coming close to full A cup and last couple of days they suddenly decided to grow (kinda torn between being happy or concerned).
I can male fail (involuntary), but have no issues to pass as a dude if needed.
And I have to admit that I am much happier not to have testosterone in my body, than to have estrogen. At least, I guess I kinda feel so... Not that I mind having estrogen, but getting rid of T was a higher priority.

Having the T blocked has made a world of difference, I think much more clearly now.
The noise is still there a little, but at a level I can easily deal with.
My personal situation called for the need to keep that, but back off on the E for a while.
I've been back on it for a month a so, and it's a good addition to the blocker, life is smoother.
Last weekend I took a kayak trip and pushed the E up considerably.
It brings out the protector mode of my feminine side very well, something that goes hand in hand with keeping me level headed for some reason.
The 'she' side of me is really the tougher side of me, the side that has kept me going through life.
It really is kind of hard to explain...
It's really weird how we each react in the different ways we do, but all in all, even low dose seems to be a life saver for many.
Ativan

I'm fully binary, but taking what would definitely count as "low dose" at a level that most would call ineffective (it's within the range of what's prescribed to menopausal cis women), so maybe my datapoint will help as an outlier/extremely responsive case.

Coming up on 5 years HRT.
Vivelle Dot patch, one of the standard doses provided (=I'm not doubling them up or anything).
Pre-op T levels were between 25 and 37 ng/dl (female reference range is 15–70 ng/dL); post-op haven't been tested
42DDD

I've also been living full-time since about four months and couldn't back-pass as male by six months.

Low dose hrt
1.  How long have you been on it?  3 yrs, 4 mths at transition dosage but reversed this.
2.  What meds and mode of delivery?  Spiro and E.  Like Ativan I have worked with my endo to find the dosage which achieves my desired results - nil dysphoria and emotional richness.  This meant that we trialled Spiro alone, E alone, then increasing one and then the other to determine physical and emotional impact.  We are now at the stage where I have his approval to vary dosages within approved boundaries between my 6 monthly check ups. The reduction in body hair, fat redistribution, softer skin, muscle deterioration, more lustrous hair and brittle nails seem to be par for the course.
3.  If known, what are your serum levels of E & T?  Told that I am within the normal bands for a cis F in their 50's
4.  Roughly how much breast development have you had?  Because at one stage  I took a transition level my breast developed to a C.  I had a bilateral breast reduction to buy me time .  Since then they have restarted and now would be A/B.

Safe travels

You are the most courageous person I have ever known, Aisla,  I could never, ever do that to my boobs.

To be more succinct:

I was a very slow ramp up, maybe due to age.  So in the first 9 months, it was low dose by mtf standards, and I developed A's that were not full, distribution that was fairly cool, my eyes changed to two colors in the iris from the Spiro, and it was ok.  But, on the sublingual orals, the crashes were daily and hellish, exhausting.  My body does not do orals well, and I varied on low dose in the range from 25 to 100 E.  35 T.

Then, we threw in the towel and went to estradiol cypionate.  Not valerate, cyp.  It packs a whallop and has sent me to over 300 E, the boobs are slightly fuller and growing and sore right now, and there are other sublte changes that are essential for me personally.  I wish I could get C's, B's would be heavenly, and I am greatful for the full A's.  And the body looks good.  So  do the face and eyes, when you read past my "mask".  But I stick a long needle into my leg once a week.  Desperation makes anything possible I guess.  Hope I don't trigger anyone with that.

Bottom line, Spiro and finesteride alone made me feel really sick.  Only with the added estradiol did I do better.  And even on low dose, the difference in well being was enormous.

I think low dose is great for many here.  I am far too addicted to estrogen to not let the endo take it to max, that's his call, I stay totally out of it.

Looks like I am overdosed on e-cyp my numbers are in the 500-700 range.... took us all by surprise.

So, that stuff is potent, but good for stable numbers, and you gotta watch it with bloods.  Low dose would be a cakewalk.

I feel a bit strange right now..... lol.  Teenage beauty queen levels.
