How's vasodilation? Do you have prominent veins or barely any if at all? Do you get good pumps from working out? Do you deal with shrinkage often? Do you often deal with cold extremities?
Do you deal with muscle tension?
Pretty veiny in my arms especially. I can easily get a pump when using D3 And/or magnesium (also using kuinone currently) , but those are two serious libido killers. Without those I can barely even get a pump. I'm thin boned genetically, not much natural mass or fat. Diet and extra cals don't do it for me as far as putting on noticeable muscle mass. Lowering estrogen is really the only method I have found to get noticeable workout results.
As a result I've been stuck in a love hate relationship with D3 and magnesium for a while. For reasons even beyond working out like mood, energy, better sleep, reducing anxiety . Basically anything "good for my body" seems to be bad for my libido. I've also tried many other cofactors like A, zinc, B vitamins, K2, etc... Too many to list. Most of those things come with their own libido issues so adding them to an already bad libido situation is just worsening the situation. Many things hurt my libido, such as caffeine. I also avoid that.
As far as shrinkage, magnesium definitely accomplishes that.
