Is this your first time using SARMS?
Cardarine and SR9009 are very similar. Both are PPAR up regulators. Both will increase fat loss, endurance and recovery. Cardarine is a little bit better for endurance and SR9009 is a little bit better for fat loss.
If you have never ran SARMS before, I would stick with the classic triple stack - cardarine, ostarine and s4. It's very effective and fairly inexpensive. If you get the triple stack cycle option on SARMS1.com, you will have enough to run a full 8 week cycle at the recommended dosages. The triple stack cycle is discounted so it's only $350. All that's left is to buy the HCGenerate from n2bm.com.
The whole thing will cost you less then $500 when it's all said and done and last a full 12 weeks.
