Strength no. I see you said dudette, so the following will not apply. But I have done a 200mg shot of prop before, and 1-2 days later my sex drive is through the roof. But this only works well with a short ester.
As far as strength, I will have to agree with others that you have to run long enough to get your blood levels up and steady. For prop you could pull that off in about 1-1.5 weeks with a decent front load of 200mg first two days and 100mg/day there after.
HOWEVER, being female, I am not sure what it would do...grow hair on your chest? LOL.
I never feel particularly stronger with only test. Like Tai said, there are other things out there that will boos strength MUCH better. But if it is for a female (you) there are not a lot of compounds to choose from.
Anavar will help strength and I know its safe for women. . .
Someone else chime in. What compounds that boos str are female safe?
