SARMS are going to be your best option. They will not increase size and strength the way steroids do but they will directly increase fat loss, endurance, recovery and small increases in lean muscle mass. They are extremely minimal in the way of side effects. They do not effect liver values, cholesterol levels or blood pressure. They do not aromatize into estrogen so side effects like gyno or water retention are impossible.
SARMS are extremely effective by themselves but stacked together, they are even better as they work synergistically.
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. Thats what I recommend based on your goals and stats.
You can read up more on the triple stack here:

After the triple stack, run a mini PCT. 4 weeks of the following:
clomid at 25mg/day
HCGenerate ES at 5 capsules/day
SARMS are minimally suppressive, there is no risk of aromatization (therefore no estrogen related side effects) and legal to use. You can get everything you need off sarms1.com, n2bm.com and ag-guys.com
