Although I'm sure that nothing that anyone tells you here will sway you from running a cycle, I'm not sure how much approval you're going to get.
You're not done growing, your natural test levels are as high as they'll ever be, and i'm almost positive that you haven't come anywhere near a plateau in your training.
Eat right, train right and forget the sauce for now.
Oh, and I don't think any thing is 'safe' when it comes to anabolics. Tabs are just gonna be hard on your liver. Just my 2c.
