I have a couple questions.
1. My pharmacy won't have the kind of testosterone I'm prescribed until July. My endo said I can take something else in the meantime, but just in case there's a lot of confusion over that and/or it takes awhile to get ahold of him... How long would it take for the reversible changes on T to start reversing? What effects would skipping for about a month have?
2. I do have a little bit left, but I also need to replace one of my needles. I have the syringe and the needle that comes with it, but I usually draw with one needle and inject with a different one. Is there anything wrong with drawing and injecting with the same needle?

Not sure about the 1st question but as for the 2nd, it's fine to draw and inject with the same needle. I've always done it that way.

It is more painful to use just the one needle. The vial blunts the needle.

It is easier to draw with a larger needle than needed to inject because of the oily viscosity.

Thanks for replying, Kat and G.

I've been pondering your second question and think some minor things would start after a couple weeks but I don't think anything noticeable would happen in just a month.

I hope you can get T in another form without too much hassle.

Do you live where you could get it from Stroheckers?
