Pro-hormones such as 17 methyl dione are a TERRIBLE idea for females. Pro-hormones and steroids can cause permanent emasculating effects in females. Things like clitoris enlargement, facial hair growth and voice deepening.
The best option for females is SARMS.
SARMS are a completely different class then pro-hormones and steroids. Steroids and pro-hormones have two distinct but overlapping effects:
1. The anabolic effects which promote growth
2. The androgenic effects which promote an increase in male sexual characteristics
The problem with the androgenic effects of steroids is that they can cause side effects. Especially when taken by women.
SARMS on the other hand are completely anabolic substances so there are no risks of developing emasculating side effects. SARMS were originally developed to prevent muscle wasting in people with diseases like HIV and cancer.
SARMS are extremely effective by themselves but work even better when stacked together as they work synergistically.
A very common SARMS cycle is the SARMS triple stack. The triple stack is combination of S4 + ostarine + cardarine.

Cardarine is a great SARM for fat loss and endurance
Ostarine is a great SARM for recovery
S4 is a great SARM for strength gains
You get the best of everything by stacking the three together.
SARMS are only minimally suppressive of natural testosterone production so all that is needed as a mini PCT after a cycle of SARMS is a good natural testosterone booster like HCGenerate ES from n2bm.com.
