Hi Beverley,
Chrissie grew well on PM UK.
L-arginine is a body builder food. I can buy it in a high street drugstore here. If there is no L-arginine, L-glutamine or L-proline will do: your body can convert one into the others. Or a multi-aminoacid blend: MydreamisGcup used that for a while. Increasing meat in your diet will also help, but I don't know how much it will take to match the 10,000 mg L-arginine the ladies are taking.
They are both young women, so their Human Growth Hormone (HGH) is naturally high. Even then, they supplement the L-arginine, for more HGH.
Another thing young people have in common is low Sex Hormone Binding Globulin (SHBG). It increases naturally with age. It will chemically bind to much of your testosterone, and to some of your estrogens and PM. The hormones become inactive that way. The only thing I know that will decrease SHBG almost instantly is oats. Just oat flakes, as in breakfast cereals, will do. Oats also contain vitamin B6, which is good for NBE, but it is sedative. So eat it at night, in porridge.
The decrease in SHBG will release some free testosterone. If that is converted to DHT, it will increase your libido. But if you have used enough PM, the anti-androgen in PM (β-Sitosterol) will block the way to DHT, and all the free testosterone will become estrogens, which is what you want.
Another common element in the programs of MydreamisGcup and idreamofD is a good multivitamin. MydreamisGcup used a hair skin nails multi, and idreamofD found a teen multi, after I advised her to watch the amount of zinc (between 12 and 35 mg) and vitamin B6 (between 2 and 10 mg). Other vitamins to look for in a multi are at least 50 mcg of vitamin B12 and 400 mcg of folates or folic acid. There may be more: maybe I should ask the ladies to list the full composition of their multis.
Both were on birth control, which means they have plenty of progesterone. If you get foggy thinking or headaches, those are symptoms of estrogen dominance. But let's just see if you get that far with L-arginine, the oats, and the multi. If you do get the headaches, you may need some progesterone, from fennel tea or fenugreek.
