I had my testosterone level checked 3 yrs ago and it was on the low end.
Started injecting 1/2 a mL (100mg) every 7-10 days. Got my level around 800-1000.
Drink protein shake every afternoon between lunch & dinner. Exercise what I can.
It saved me. A woman's level should be about 1/8th -1/10th of mine.
If you test low but within range, its not good enough.
Testosterone Cypionate 200mg per mL is what I use with script from Walgreens.
1 10mL bottle will last a female 1 year or more. Its a steal at $100.
Cancer risk? Well, MS isnt exactly life prolonging in itself.
For a male I notice it also works like but better then Viagra.
Women supposedly benefit from it as well.

Get total testosterone checked and post results.
Im on Tysabri for 4 infusions and still declining. Adding a chemo drug next.
