Overall first impressions upon loading: Normal load time. Nice slider, however some images seemed distorted and low quality. The colors are nice (albeit I am color-blind) and layout looks really good. Blog looks good too.
What I liked: The colors, your favicon and website looks great.
Things I would like to see: I realize that your slider contains links to your recent blog posts, but it would seem natural to have some article/blog post teasers right below the call to action for the Forum. In fact it might look good to place some teaser blog links between the 4 products you list and then place the adwords below the teasers. Also it would be better to refrain from "shoe horning" in images to the slider. However, I realize that it is hard to find stock images big enough to cut down or fit the exact size... but it would be nice.
Notice also how the text floats properly around the DANABOL (DIANABOL) image. The three other images next to this one do not. I would fix the floats so that the text wraps around the side of the image like the DANABOL one.
Text floats look better but the margin bottom of the image is too big. IMO the text below the image is too far distant. Typically I like to pad/margin the text equal amounts from the side and bottom. Sometimes though a little more distance can be acceptable below the image but not too much. I will eyeball it until it looks natural.
Not a design expert, using IE, I noticed that you just don't seem to have a front page. It begins with a list of blog entries and no other attractive content. I would like to see a banner and some more visually interesting content on the main page.
Since its Wordpress, you could try some other themese pretty easily. Content is a bit interesting, but I'm a bit confused about the stance. I guess your site supports the use of steroids? With that kind of message, maybe you could include a disclaimer or some FAQs about legal issues and common misconceptions. Best wishes.
