If she can get fro a doc ( pretty hard to do ). Online is very possible but, must do research and not just buy from the first thing you find because literally for every good lab there are 3 shitty or fake ones. Will just have to lay around and find a reliable source not the hardest thing to do but, can take time.
Depends on what she is taking if she has never ran any PED before then I recommend starting with...
Anavar. Normally for a male a Anavar only cycle will get you flamed hard as hell but, for a female it is a very good option. Anavar is a very mild drug and woman I know who have used it really like it for decent strength and size gains. Most common approach I have seen is 20mg daily for 6 weeks. all report very minimal sides other than swollen clitoris but, most don't mind due to the increased sexual stimulation and it does go away when off.
Equipose- Another very good option for females especially if she is already lean will help her lean out a bit more but strength and size gains are much more impressive with this drug than the Anavar but... it can have more sides come along with. Most I have heard is voice started crack and enlarged clitoris. Big problem with this drug is that IF and it is seldom it happens but IF sides do show up she will just have to ride them out for 4-5 weeks. Eq takes about that much time to really kick in and clear the system so... As for dosages recommend starting at 50mg a week if after 5 weeks the cycle is going good then she can up the dosage if she chooses so to say 75mg. Another 2-3 weeks if still not seeing sides then up to 100mg. Cycle length usually runs 16-20 weeks.
If she is looking for a serious cycle for a female then she can combine the two mentioned for great gains
EQ 75-100mg a week
Anavar 20mg daily
There are other options but these are the friendliest on a female if she wants to remain feminine. If she is willing to risk it then Test Prop for female can be amazing for strength but facial changes, hair loss or gain, bloat, voice change and slew of other things are all very good possibilities if the drugs are not kept under strict supervision. These side effects are very possible with the drugs above but are much less likely to happen.
- She wont NEED to take a Estrogen blocker but, my wife personally loves running Eq and Nolvadex just to really keep estrogen and bloat away. AI's at these doses are not needed either atleast not with the drugs mentioned. If she runs Anavar then a good Milk Thistle supplement is not a bad idea how ever doses are so low her liver should not have a problem at all.
Women don't have to run much accessory drugs because one higher estrogen is not as big a deal in a female and also the drug doses are quite a bit lower the drugs don't put as huge a strain on the body... also as added benefit there cycles are usually dirt cheap due not needing a shit load of stuff.
