In the not-so-long-ago, Biotest decided to change things up a bit. Biotest has always had a website where you could order supplements. Testosterone.net/T-Mag.com linked to it.
THEN they did a great thing: they pulled back from supplying GNC and others with all their supps, made them available directly, and dropped prices to reflect the lack of a middle man.
Along with this change, they did something even more cool: they continued to sell certain supplements on the Biotest site, but to members of T-Nation, they made available more powerful formulations at the better prices.
Therefore, a run-of-the-mill wannabee lifter who Googles tribulus terrestris can find it at Biotest.net. But to the rare ones who find their way to this here website, hang around and read, like what they see, and sign up...THOSE people have accessible to them more powerful supplements at better prices.
(...and you can read about it all in my forthcoming book: "PCT, TLC, & TC on the QT: The Secret History of a Website That Cared and Changed the World of Bodybuilding Supplements"; available soon from Tongue-in-Cheek Press)
If you are past the age of 30, just whip out your credit card and click on the "Full Product List" bar, willya? If you are younger, you've got time to read up and figure out what's what.
