Is truecrypt still safe?

I want to fully encrypt an disk on Windows 7 , but i don't trust bitlocker and truecrypt has announced as non safe ,and many rumors about NSA being able to decrypt it and with it weird end it's better to avoid it. So what can i use? Open source is better ,and what is the most secure encryption combination today ? I see many people still trust truecrypt are them at risk of anyone easy access the data?
