More energy physically, mentally or both?
I understand and suspected as much regarding the energy.
Feeling more energetic mentally and physically translates directly to quality of life.
You cannot expect miracles, and as i said the overall well being is the goal. You won't necessarily feel huge boost but the effect is still there you know.
These things depends on so many factors regarding stress & life situation ranging from your bodys function to mental side etc.
I personally did gain strenght and endurance and depression like feeling
i had for some years went away. It has made me mentally stronger too.
Ofc i have to add that yes it helps to build a bit of muscle too can't deny it though you cannot compare it to BB cycle.
Imo it's best to think it like you'd feel the same as 25 years old man normally would. All the same things that used to affect your well being negatively, still affects you. It won't make you immortal.
