Hi guys, So I purchased some Sust. 350 from one of the sources on here couple weeks ago for my TRT. I pined half a mil or about 175mg into my left delt last Tue. Didn't have any problems for a couple days and then started to feel a little pain in my delt by Saturday AM and by PM the pain was progressively worsening. Last night I kept waking up from the pain every time I moved. Today my left deltoid/ Tricept is swollen and very painful. Don't know why but its the worst pip I have ever experienced. I took all precautions as always, cleaned the top of the vile and my entire deltoid with alcohol prior to pining. Used a new 25g 1 inch needle brand new and wasn't doll or anything either, one to draw another to pin. Anyone have ever experienced this before? please advise.Tnx
