i have been using test 400 and deca 300 for 3 weeks now, the first 2 weeks the injections in my glutes were a bit painfull but tollerable, however the 3rd week i had large hard what i believe are cysts in them that have just started going down after 6 days abd has left me worried about my next injection. i always follow strict rules when injectin so i think these are sterile cysts i read about as i shower, wipe the top of the 10ml vile with a alcholic swab, then the injection site with a different alcholic wipe, and always inject as your suposed to, drawing back on the syringe and injecting slowly. any information would be much appretiated guys as this is only my second cycle. thanks!
