libido

I came off a sarm cycle over 3 months ago oh, it was just using rad 140 and I had no issues while on the cycle. But a few months later I'm noticing puffy nipples and my libido is extremely low. Do you think that I was really taking sarms or do you think that something else could be going on

I was thinking of running some whey protein for the next couple of months but I'm starting to second guess myself because some of the people are saying that it can affect your libido and erections strength. I don't ever mess with dairy but I want to get more protein in my diet
