Daily injection scar tissue?

Can daily injections cause muscle damage and atrophy? I inject daily alternating between shoulders only. Could this be a problem long term? I use a 0.5” 28 gauge insulin pin.
 
I do daily injections, shoulders and VG. I’ve been injecting daily for over three years so far no scar tissue.
 
I’ve been doing daily injections for about a year. I rotate between shoulders, thigh and the ventrogluteal muscle as Vince mentioned. I like the VG muscle the best. I never feel a thing and it’s an easy spot once you’ve done it a few times.

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.
