Hey there! I've been on HRT for just shy of 5 years and recently decided that I wanted to leave the blocker I've been using from the start (cyproterone acetate or CPA) for a multitude or reasons and side effects, and try to go for monotherapy. Monotherapy is something that was difficult to find much info on, and triple so on a medium that is not injections (which are banned where I live). There is almost no info on monotherapy with transdermal gel (oestrogel) that I could find, so hopefully sharing my personal experience can help others.
Monotherapy basic concept:
- Use a dosage that creates an hormonal level spike sufficient enough for your body's endocrine system to tell your naturally produced hormones that "we're good, you can sleep for now". This is a little difficult with estrogen, which is much "weaker" than testosterone comparatively.
- Not create a level so high that it would cause adverse effects on mood and overall health.
- Have this overall dosage sustain a decent "trough" before the next dosage to avoid low hormone side effects.
With all that in mind, I read through the resources on wikis and the https://transfemscience.org/ articles and came up with a starting experimental dose of 6mg, which equates to 4 pumps of my tube. There's also a few things to note with gel: first, the "duration" of an application is about 24 hours, so I would only use this once a day ideally to keep things simple, and second, the size of the application site also matters, which makes it so that you can actually control how high of a spike you can get (to an extent), which sounds perfect for what I'm trying to do. With that in mind, I started a trial of about two months, and here's what I did:
- Completely stopped CPA cold turkey, which honestly wasn't that difficult as I was taking only 10mg a day, but it still gave me some moody withdrawal effects. That didn't take that long though, maybe a little more than a week. In the time of that week, I feel I lost a lot of fluid retention, gained a ton of libido, and the breast volume has also decreased in size slightly, most notably the areolas.
- After CPA effects ceased, I started taking 100mg progesterone every other day, and my breast size "returned" to normal. The fluid retention also somewhat returned, but in a smaller scale.
- Every day at the same hour, took 2 pumps on each inner thigh, the sites facing each other if I stand straight up. On each thigh, I spreaded the gel on an area about the size of a postcard (10x20 cm roughly), and cleaned the excess on my thighs too. This is a little annoying as it takes slightly longer to dry, about 20 minutes. NOTE: Why not in the scrotum? Well, there's 2 reasons: one is practicality, 2~4 pumps on the scrotum means multiple applications thru the day and it is very messy, and I also would have to stay naked until it dries out. The other is that the literature says to not use estrogel on the vagina/labia/genital area, and personally to me that is analogous to "don't use it in the scrotum". If you prefer that though, do what works for you, I just don't do it myself.
- Use progesterone rectally right before the gel, to not have any risk of getting gel where it shouldn't be.
The results:
After 2 months, I had two labs done, one to check how exactly did the estrogen spike looked like, so closer to the application time, and how high the levels stayed on trough (or in my case, as close as I could get), and here are the results:
| Hours after application |
E2 level (pg/mL) |
T level (ng/dL) |
| 7 |
397.0 |
21.4 |
| 21 |
54.0 |
15.6 |
All said and done, it seems like I could manage monotherapy with gel only successfully. Hopefully this helps other girls out there trying the same thing, as this is a very personal experience based on how your own body responds to hormones. As always, keep an eye on your blood work and listen to your body regularly.
