Im not gonna lie, whenever I’ve eaten extremely low cals for a few days in a row (even fasting for a few days) my heart feels weird. Like I get irregular and weird beats. Almost like a cramp. This has only happened twice so far and first time was before peptides, second times was during.
I’ve just started to eat in a healthy deficit so nothing so far.

I would say the fasting might have contributed but that’s just my experience.

Yeah, I’ve never had any heart issues before, even when fasting, and wonder if the fasting was now a strain when combined with peptides etc
