Feminising GAHT injection - EUn - 3rd (and final) loading dose Hover or focus to reveal Sensitive

Tonight was our 3rd injection of EUn (estradiol undecylate), and the final weekly loading dose before we switch to fortnightly maintenance ones. We did 12 mg intramuscularly into the vastus lateralis in our right thigh, using our Union Medico 90° "Super Grip" auto-stabber. Painless and easy injection tonight. Maybe too easy? 🤭 Anyways. Next injection will be in a fortnight. It'll be weird to not do one next Friday, but that was one of the key draws of switching to EUn

Feminising GAHT injection - EUn - 2nd loading dose Hover or focus to reveal Sensitive

We had considered not doing these posts, where it's now public that the Cult of Shiv server will shut down at the end of October, but meh: maybe these posts'll help somebody between now and then. Today was our 2nd injection of EUn (estradiol undecylate). (1st post here.) Today's injection was 12 mg of EUn intramuscularly into the vastus lateralis in our left thigh, using a Union Medico 90° "Super Grip" auto-stabber. Zero issues with the injection. Little bit of blood when pulling the needle out, but that's partly because we lost a little grip on the Z-track (hand grip issues FTL) 😅 It was only a week after the 1st one, where we're doing 3 lots of weekly loading doses at the intended maintenance dose but half the injection frequency, rather than a single loading dose of about 2 to 3 times the maintenance amount. After the 3rd loading dose, the frequency will switch to fortnightly. #TransDIY #TransHRT #TransGAHT #DIYGAHT #DIYHRT #GAHT #HRT #FeminisingGAHT #FeminisingHRT #E2 #Estradiol #EstradiolUndecylate #transition #trans #transgender #NonBinary #TransFem #injection #TransHealthcare #queer #LGBTQ+ #LGBTQIA+ #LGBTQIA2S+ #UnionMedico #AutoStabber

Simulation of switching over from EEn to EUn Hover or focus to reveal Sensitive

Okay. So, there are 3 main estradiol level simulators that we find useful for different reasons. Trans Fem Science.Estrannaise.Grey Oasis Trans Fem Science's one is the OG. It's fairly simple to use, but lacks the features available in others. We used to find that it vastly overestimated levels, but we've recently-ish discovered that many different things can raise estradiol sensitivity overall, or your level on a blood test on a given day, so we're more forgiving of it now. Estrannaise is more advanced, and fairly simple (ish) to use, once you've got the hang out of it. It's particularly helpful for calculating ramping up and/or switching from one ester to another. However, its level estimations for undecylate are very low and seemingly very out of touch with other simulators, making it difficult to recommend for calculating ramping up or determining doses. Grey Oasis is based off the Trans Fem Science simulator, but gives you the ability to calculate ramping up or switching esters, albeit in a non-user-friendly way. It also looks like the creator hasn't touched their website for a couple of years, so there's always a chance it may just disappear one day. If you want to simulate a switchover from one ester to undecylate on Grey Oasis, we recommend getting it to simulate a ramp up on your current ester, followed by the same on the other. For example, this will simulate a switchover from EEn (4 mg weekly) to EUn (12 mg fortnightly): 0/6/EEn, 7/4/EEn, 14/4/EEn, 21/4/EEn, 28/4/EEn, 35/4/EEn, 42/12/EUn, 49/12/EUn, 56/12/EUn, 70/12/EUn, 84/12/EUn, 98/12/EUn, 112/12/EUn, 126/12/EUn, 140/12/EUn, 154/12/EUn, 168/12/EUn, 182/12/EUn, 196/12/EUn, 210/12/EUn, 224/12/EUn, 238/12/EUn, 252/12/EUn, 266/12/EUn, 280/12/EUn The same entries give a vastly-different simulated result in Estrannaise. (We've added the stable dose line for comparison.) From what we've been advised from others within the homebrew community who have more experience with EUn, there are a couple of big reasons for discrepancies: There's not much underlying data for EUn, and the data available is old.The carrier oil has a major impact with EUn, changing the effective elimination half-life (t=½).~21 days in MCT oil.~34 days in castor oil. This is probably part of why Estrannaise shows such a slow ramp-up and low values. #TransDIY #TransHRT #TransGAHT #DIYGAHT #DIYHRT #GAHT #HRT #FeminisingGAHT #FeminisingHRT #E2 #Estradiol #EstradiolUndecylate #transition #trans #transgender #NonBinary #TransFem #injection #TransHealthcare #queer #LGBTQ+ #LGBTQIA+ #LGBTQIA2S+
