Last night I filtered my primo at 200mg/ml. Well long story short my last filter popped on me at around 15ml and I ordered more and kept the rest of the oil in syringes until it gets here. Anyway before this primo cycle I ran mast and I would inject in my pecs 1ml each quit often. Well yesterday I felt a little lump on the top of my chest I guess due from the test. Story short I injected 1cc in my left pec and 1 cc in my right pec I woke up last night in some pretty bad pain. My left pec was very swollen and very knotted. I ca barely stretch it. It hurts pretty bad however my right pec is a lil sore but tolerable any ideas wtf this is? Do I just need to give my chest a break and start injecting in my shoulders?
