SARMS are a great choice for females because there are no risks of developing emasculating side effects.
I would have you run the triple stack. The triple stack is combination of S4 + ostarine + cardarine.
S4 will increase lean mass and strength
ostarine will increase recovery
cardrine is the best SARM for fat loss
You get the best of everything by stacking the 3 together.
There is a reason the triple stack is so commonly recommended. It works.
You can read up more on the triple stack here:

^A female should use 1/2 the dosages listed in the article.
After the triple stack, run a mini PCT. 4 weeks of the following:
HCGenerate ES at 5 capsules/day
Nutrobal would be another great option but it's very expensive. I would keep things simple for a first cycle with SARMS. You will get fantastic results just from that.
