I shot myself with testosterone today, I do it every two weeks. I am perhaps the last man not using the gel. The shots are cheaper and easier.
So I open my ampule and stick the nozzle of the hypodermic in and pull the plunger out. The fluid moves into the body of the syringe due to the decrease in air pressure. While it does this, bubbles form in the liquid.
Is it boiling? I suppose because of the decrease in pressure we would expect a lowering of the boiling point.
What do you think?
I’m going to say no. The amount of vacuum you produce will be limited by the pressure drop induced by the static head required to pull the fluid into the needle and the frictional losses and won’t be enough to allow boiling. What you’re doing is reducing the pressure enough to allow dissolved gases to come out of solution.
Is that not boiling? (Or what does boiling mean? Where do the bubbles come from?)
It looks like boiling, but it’s not bubbles of water vapor coming out. It’s just dissolved nitrogen and oxygen, like the bubbles you see on the sides of a glass of water that is let to sit undisturbed for a few hours.
Boiling is when the substance itself turns into a gas.
Displacement of dissolved gasses from a dissolved state, to a gaseous state, is not boiling…
OK. Many thanks.
Okay, hope this isn’t too personal, but I gotta ask…what condition do you have that requires you shoot testosterone? I can imagine a few reasons you might have to do that, but you started this thread so nonchalantly that I’m figuring you must’ve discussed this somewhere before and I missed it.
Oh, no biggie. A tumor mass has damaged my pituitary gland and so my endocrine system is shot all to heck.
Technically, it wouldn’t be the testosterone boiling anyway, since it is in a solution (I assume saline). It would be the solvent rather than the testosterone.
I seem to recall it is testosterone in oil.
That makes sense. I hadn’t thought about it but testosterone would not be soluble in aqueous solution. Then the answer to your question depends on the boiling point of the oil. I don’t know what type of oil they use for that type of thing.
