Two weeks ago I wrote about how my biceps injection with tren ac in the right and test enanth in the left gave me a muscle soreness akin to how you feel after a good workout. Well, last night I did the same exact thing. I had a killer biceps workout and then in the evening I injected my biceps. 30 minutes later my biceps were super sore (in a good way). Later that night I was jacking off with my right hand and my right biceps got a painful pump. I love this feeling! Its probably the stretching of my biceps facia but it feels just like lactic acid burn. If its just like last time this biceps soreness should last for about three days.
