Thanks for the info. So just to give a quick update -- I don't know if it's just a fluke or what, but the Anavar seems to be causing a significant spike in resting HR along with a few other weird side effects (numbness/pins & needles sensation in fingertips, anxiety, notable nausea). The feeling of having an overstimulated CNS was so strong an hour or so after taking 20 mg of Anavar earlier that I actually skipped my cardio.
The weird thing is that I didn't notice any of these side effects when I ran a cycle back in 2019 that included Anavar. The Anavar I had back then was from a different UGL than what I have now, but otherwise I can't think of anything that was different then vs. now.
From what I'm reading, it looks like there are plenty of anecdotal reports from other people who've reported the same effects, but I think it's weird that I didn't notice any of these symptoms back when I took Anavar in 2019.
