I was wondering about insulin sensitivity in regards to a certain drug that I take (prescribed). I've read several studies and it has the very real potential to lead to insulin resistance and, with most people who take it, weight gain.
The reason I ask is because I was wondering if this would affect my progress and goals in regards to building mass and lifting heavy shit. Should I test my insulin resistance? How would I know if it's affecting my ability to build muscle? Is weight gain the only sign?
I was reading that insulin resistance in muscle will inhibit glucose uptake and local glucose storage which is why I was concerned as I had been feeling low on energy for the past month-ish during my workouts (my squats have been destroying me) and have even seen a steep drop (and reversal) in progress (medicine has stayed the same for the past year). For example; I repped 250 x 9 for squats on week 3 of 531 cycle 2, and on week 1 of cycle 4, I struggled to rep 245 x 5. The week after that I repped 260 x 1. It's this significant drop in energy that really has me worried. Cycle 4 is this most recent month of December. I dropped back down in weight for week 3 and squatted 250 x 4.
I'm not overweight in the slightest (current pic is about how lean i am right now), which is why I think it might be something else (lack of food, perhaps), but it's a definite concern of mine.
For reference, I consume ~6000 calories/day and swing between 205-210 lbs.
Thanks for reading in addition to any input you guys may have.
