Elvia, I could go into a lot of things with you but in my opinion I don't think that stuff is any big deal.
I know exactly what you want to do but here's what you have to look at. That stuff raises test but blocks estro. That's good and all BUTTTTTT you can only raise your test so far. You have free test and total test. Now you may raise your test but it's not going to be freee so it's really no good to you. You want a product that frees up your test.
This is totally my opinion but it's based on years of using these products. There are two I would take that are natural(not going to mess with your hormones like your friends Tren product). One is Diesel (

There is another company call Primordial Performance(I think this is the spelling) and they have a topical spray that raises your test. I haven't personally tried it but I have several friends that said it's very good.(I have tried several of their other products and I have nothing but great things to say about them)
Someone mentioned NO Explode. This is a staple for me, I have to use it to workout anymore. It has creatine in it so you don't have to use a separate creatine but mainly gives you energy and a great focus while lifting. Your recovery time is also helped which is always big. NO Explode and one of the products listed above and you'll be feeling very good in the gym. Take some protein within 30 minutes post workout and you can't do much better.(outside of your diet which is always the most important thing).
I'm writing this in a hurry so if I missed anything just ask. I posted, I think in Woodson's thread, about how to raise your test with your own products if you want to check it out.
