Should I draw with the same needle I inject with?

Does drawing with the same needle as injecting with dull the needle? Should I draw with a bigger needle and backfill a smaller insulin syringe? What do most of you guys do? Thanks
 
I draw nandrolone in my 1cc 30ga 1/2" insulin syringe then backfill testosterone and HCG that way the needle only gets used once before I inject it dose seem to dull somewhat though I don't know if that's because its a smaller 30ga needle
 
I choose to use the same needle for a number of reasons, one of which is wishing to avoid any potential loss of testosterone (it would be a very small amount) in the transfer. But, there are many who employ two needles with no issue. I can't imagine I'd notice any dulling of the point.
 
First couple years I'd draw and inject with different needles. Now I'm using 27g, 1/2" and both draw and inject with same needle. I don't think only 1 poke through the stopper is enough to really notice the needle becoming dull.

In my case i'm not wasting a lot of testosterone when changing the needle. But in the syringe there is always some testosterone left in the front space (where someone puts the needle on it) about 0.05 ml. Do u use special syringe where there is no such space? I'm using a 24 G syringe. And when I split the 1 ml (250 mg enanthate) to four syringes, then I'm loosing about 0.05 ml x 4 times testosterone (0.2 ml). Any thoughts about how to avoid that?

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.
