question from a user

What is the recommended needle gauge size to draw out Testosterone Enthanate oil solution? I tried using a 30g needle, and it didn't work. I had to return to CVS, and they gave me a 22g. Would a 25g needle work? I am trying to find the right needle/syringe combo so I can administer myself subq vs IM. For example, would a 25g ½ inch needle work for subq injection?

It depends on the concentration of medication typically. The higher the concentration the more like syrup a substance acts as & the lower the more like water (for Testosterones in general).

For drawing up, we've had men use 30g needles just fine, though it does take a bit longer. Sometimes this is standard if they're doing Subq injections & the needle isn't exchangeable, but we usually go with 29g in this case.

For IM we usually give 21g draw needles & 25g injection needles, though 25g draw needles would work just fine as well. I personally draw my TRT with 25g needles.

The main difference is speed. The larger the needle the faster it goes but (and this isn't a major concern) the more it can hurt the rubber.

Overall most needles work if you do a few tricks. Try warming up your vial next time either by using a hot heating pad or hot tab water & letting it sit for 3-4 minutes under them (and then clean the vial). You'll find that just a bit warmer than room temperature has the Testosterone flowing much easier.
