Testosterone, B12 and HCG all in 1 shot?

Just switched from cream to shots for testosterone. I’ve been doing HCG and B12 subq. I’m not a fan of needles so I’m asking if it makes sense to buy a 2 or 3ml syringe and put all 3 in the syringe and inject IM at the same time?

Testosterone, B12 and hcg all at once? I’d probably have to use a few needles to draw into the syringe and then use a new needle to inject. Currently injecting with 23 gauge 1”.

Hcg & b12 currently doing insulin needles, 29 gauge 1/2”
 
It would be nice if you could draw all into one syringe. I don't see any reason why you can't.


My wife and I were visiting family in Texas. We stopped by Mexico and walked across to a border town. One of the women was buying B12 to inject and it made me wondered how high of a level do you get when you inject B12?

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
