@haidut If red blood cell deformability is among the sequelae that endurance exercise produces, I wonder if something like pentoxifylline might be useful. I understand that much of the damage that occurs to red blood cells in ultra-endurance exercise is secondary to the mechanical strain to which RBCs are subject due to being physically compressed at the soles of the feet with every step or else during their turbulent and high pressure flow through arteries of a person basically running for their lives, but I would like to know if using a stack like Pentoxifylline + Meldonium to cut down on the FAO, keeping carbohydrates going every 20 minutes or so, might compare.

There are extracellular and nucleus prolactin receptors. Prolactin binds both and this drug, as it's an antibody, only binds to the extracellular receptors giving us an idea of what effects anatagonising the extracellular receptors does but does not tell us what the nuclear receptors do and therefore cannot show the full picture of what prolactin actually does. There exists many case reports of hair loss from dopamine agonists, so your suggestions may be harmful in this regard. Estrogen receptor alpha for example has different effects than estrogen receptor beta for hair growth is an example of the flaws behind what people infer from this study

Over the past week I have worked my way up to 1mg a day. The effects maybe have increased, but the reason it might not have done so more is because of low estrogen from exemestane. I know this could be the case because I heavily sweat during naps now, one classic symptom of low E2.

@haidut i have named my kids in your honor
