Cellucor’s legendary supplement P6 Black Extreme has not only made an exciting return to the testosterone market. But is going a step further than the current muscle builder P6 Extreme which is exclusively available to GNC and a few other regions outside of the US. Despite it’s limited edition promotion, it looks like Cellucor will be distributing P6 Black to all of it’s stockists. At the moment a lot of online stores are preparing for the supplement’s arrival with coming soon banners, product pages, and some even with a price tag. Unfortunately the companies expecting P6 Black Extreme are looking like they will be selling it with the same retail value as GNC. Currently the chain is promoting it for $90, or $72 with a gold card. So for those fans who do not shop at GNC, you will probably end up paying the same as the member’s price, somewhere around $70.
