Hey guys.. I just had my first shot of Profina its 100mg test prop 100mg tren ace, so it comes to 200mg/ml. This is the 5th injectable compound i've used, but I noticed when I was injecting I had to press SUPER HARD on the plunger and apply constant preassure to get the oil in. I was pretty much forcing it in... regular injcetion pain after nothing abnormal. But why was it so hard to inject it? is it cuz the oil is so thick due to 200mg/ml??
