I'm currently 3 weeks into a primo/test cycle and I'm having some effects that I did not expect. My cycle consists of 500mg/wk of Test Cyp, along with 800mg of Primo (Robo, 2x week), plus 50mg proviron a day. In addition, I'm also about 3 weeks into a GW and MK-2866 SARMS. No noticeable gains as of yet, but I did not really expect much this early on. What I am noticing is the following: chest and arm acne, libido way down, sleep overall worse. I also seem to have quite a bit of sinus congestion, but have no other symptoms of it being a common cold. And when I exercise, the sinus congestion gets worse. And speaking of exercise, my cardio is really bad now. I can no longer make it through my weight lifting workouts without experiencing episodes of trouble breathing and having to stop to catch my breath. Prior to the cycle, the only weight lifting routine that really tested my cardio and slowed me down would be leg day, but now other workouts like chest, back, etc are all leaving me breathless at some point during the workout causing me to stop and regain my breath. Heck I can't do simple tasks around the house lately without getting winded. And my anger has been on the rise, short temper, mean thoughts. Heck it almost is like I'm on Tren, but I doubt that's the case, but I'm not sure what is going on. I was excited about the prospect of the GW to give me boost of endurance, but even that is doing nothing. I also tend to have some anxiety and that seems to be up as of late as well. Given how expensive Primo is, I hate to pull the plug this early into the cycle (the plan was for 16 weeks). But my plan was to step up the intensity and frequency of my workouts but right now I feel so out of shape I can barely do the minimum. I am not having any other symptoms of a cold/flu or something that I am aware of, and I did not expect these types of side effects. I've taken Test Cyp off an on for a long time, and was fine with it. I sure hope its not the primo, nothing I have read about its positive effects really adds up to how I'm feeling. And I still get PIP every time I inject it. I've done delts, thighs, and glutes. Each time I'm mildly sore for a few days. Pretty bummed right now.
