So I started doing T400 at 800mg about two months ago but started getting really bad heart pains and I decided that my body probably can't handle high doses anymore so I lowered it to 400mg a week.
Everything was going great until about the past week or so I noticed a drastic drop in libido.
Typically over the years, even at 400 a week I was hard like a rock at the drop of a hat, but not anymore. I feel kind of normalish, like I would off cycle.
Also, I'm starting to get sore after workouts for longer this past week or so, like as long as I would be off cycle. Typically on cycle I recover extremely fast.
Maybe try taking it back up to 800 and hope the heart pains don't come back?
