Hi, this is my first post here:

Background:

48 yrs old
190 lbs & 5'8"
10% BF

In & out of the gym for 33 years.

I've done cycles over the last 8 years.
I get all my gear from a prescription via my doctor. (compounding pharmacy in the USA)
Brand new needles, used only once and disposed of.

This summer I did 750mg of sus in the upper thigh and my leg turned hot, red and very swollen within 2 days. By day 4 it wasn't better, so I immediatley went to the ER and was 100% honest. They gave me a strong antibiotic and said I had either a staff incection or abcess.
The antibiotics worked and I took some time off from cycling.

Yesterday (after 5 months) I took 750mg of sus in the same thigh and it is so sore I am limping. Brand new bottle from the pharmacy, cleaned the top of the bottle with an alcohol pad, brand new needle 1 & half inches long 21 guage, plunged about 1.25 inches to the outside of the thigh one hand length away from the knee. My thigh was swabbed clean as well with an alcohol pad prior to inserting.

I cleaned the whole area after taking the needle out as well with alcohol.

If by Monday this isn't better, I am off to the doctor AGAIN.
I cannot figure out what the heck is going on.
