Re: what size syringe would i need for testosterone injections
My doctor suggests injecting into fatty tissue. He feels it will absorb slower and minimize conversion to estradiol that way. So I inject into the fat in my stomach with a 27g 1/2" or 5/8" needle. You can pinch a roll of fat or in my case I just bend over and a roll of fat appears. You must use a short needle here because you dont want to go in too far beyond the stomach muscle.
Most doctors will want you to shoot IM (intra muscular). This will require a longer needle and for you to do it in the thigh or butt. If you do the butt you must know where to do it so you dont hit the psyiatic nerve (spelling?). Also, with the 27g needle it is a little hard and slow to push the plunger down for T cyp because it is oil based. It might be a little hard to do that if reaching behind yourself and you might like a larger needle like a 25 g, but 27g will be big enough for the oil so its a matter of preference.
Another reason I like injecting into the fat is I don't like the idea of tearing a big hole in my muscle every week. You will probably be injecting about 0.70 ml and it will leave a big lump which will slowly dissipate.
