Im gonna have to disagree with you. Thats basically a cookie cutter mentality you and some of the others have and it doesnt apply across the board to all women.
My 33 year old wife who was always fairly lean had problems dropping the fat she put on during 2 pregnancies. Before kids her BF was around 15% and after it was 22%ish. Now that was far from being fat but she wanted her lean physique back. She could exercise 7 days a week for 2 hours a day and not lose a single pound, and her diet was flawless. It was very frustrating and she almost gave up but she decided it was ridiculous to just chalk it up to age and hormones.
Then we found out that its estimated that 25% of women who have given birth develop thryoid deficiency and that its hard to diagnose. So she started taking 25mcg a day of t3 and magically she was able to drop bodyfat like she should. Now she can eat like a normal person and only spends 5 hours a week in the gym instead of 15 and is able to have complete control over her body composition.
Of course i dont advocate jumping on drugs right off the bat and especially not AAS, but If you are eating well and exercising and not losing fat then theres a problem somewhere else, and t3 is about the safest place to start experimenting. Theres no reason a middle aged woman should have to spend all her free time in the gym each week and eat like shes on a contest prep diet just to drop a few lbs, just because shes female and thats how it goes. That mentality is simply ridiculous.
To the OP, i suspect that the GH and testosterone replacement therapy (TRT) should be plenty for your mother. Give it a few months before you start throwing her on a "stack"
