I had some slight headaches for 1-2 days when I upped my dose to 2ml. But, they subsided shorty.Littlefry, That's great to hear. Day one of week three started today and I upped my dose to 2ml, so I'm excited to see how this week goes! So far I'm up 5 lbs, which is a lot! I have also upped all my macros considerably going into this cycle so that probably explains some of the weight gain. Also I think I'm retaining a little bit of water as well. Anyways I have felt just fine so far with few negative sides to speak of other than, more muscle fullness, improved strength, and a greater anaerobic threshold as well as recovery. Today though I definitely noticed I was much much more irritable easily angered, also experienced one fairly minor headache. Now, none of this was a big deal at all! In fact these may have been sheer coincidence as work was stressful this morning and could have been the real cause. Also last night during an intense sparring session I started getting really hot, more so than usual and even after the round, I remained hot. Not a big deal but wondering if others are experiencing this.
