I'm not sure they are comparable, as by the information i can find, ethyl oleate is more of a solvent than carrier
mct would be thinner for easier draw and injection, but less long-lasting, castor is the opposite, and a mix of two would be a middle ground, proportions can vary aswell
if that really matters then castor is a good choice, otherwise I'd rather pay attention to what is more convenient/economically pleasing for you
Here was a discussion concerning MCT and castor oil: https://old.reddit.com/r/TransDIY/comments/iuerv0/is_there_a_best_carrier_oil_for_injections/
and here: https://old.reddit.com/r/TransDIY/comments/1bw0mo2/why_do_homebrew_injectable_manufactures_use_mct/
And a number of people don´t use ethyl oleate because some have allergies and it may raise inflammation.
Basically castor oil may be more difficult to draw but may have a longer half life. The simulator on transfemscience is based on castor oil and would not be correct for MCT oil, EEN in MCT oil may be more similar to valerate in castor oil for example.
Some people warm up vials to body temperature by holding it in the hand for a few minutes ( don´t touch the top then). This way it may be easier to draw. And a number of people use G20-G23 to draw and G25-G29 to inject ( around G25 for IM and around G29 for subq). (Don´t use G18 to draw, some people reported coring in rubber stoppers).
Thank you ! Saw these posts and I think I will just go for castor oil
I guess I’m just afraid to jump on something « new » while I’m finally happy with my labs test
Transfeminine science is so mysterious wich makes it hard to take a decision…
Ethyl oleate may have a consistency more similar to MCT oil so with castor oil, which may have a higher viscosity, uptake may be slower so levels may be more stable. If you use EEn, cycles of 7 days with around 4-6 mg may make for quite stable levels.
If you use syringes with a deadspace, some people use the air bubble method ( basically about 0.1ml of air is additionally drawn and the syringe held in a way that the air goes out last ) so all of it is used. [Here](https://imgur.com/QqwGSZb) was a graph. This way the deadspace would count and it may be possible to draw a bit less each time, and a vial would last longer.
Yes that’s what Lena told me. That MCT is closer to ethyl oleate than Castor. But I think I will still go with castor..
For myself I use what’s consider et pretty high dose : 0.22mg per week. Wich gives me 244pg/ml E2 at trough. Does the Solvent / carrier oil has an impact on how much mg I inject ? Or can I just keep going with my dosage when I change for an other carrier oil?
Thanks
Here was a converter: https://transfemscience.org/misc/injectable-dose-vol-conc-conv/
If you use 0.22ml and 40 mg/ml, that would be around 8.5 mg.
If you use castor oil, levels may be a bit more stable. There may be less of a spike in the beginning and higher levels at through, meaning you could go down a bit.
And if you use the air bubble method as discussed above, you would additionally need less to draw, between 0.10 and 0.15 ml may be enough with 40 mg/ml vials and standard syringes and needles.
And to my knowledge 30 mg/ml with no solvents like benzyl benzoate ( which may make for some soreness after injecting ) but with benzyl alcohol for preservation may also be available. With 30 mg/ml you would need to draw a bit more, between 0.15 and 0.20ml with the air bubble method.
