Quotation Marks

Please stop asking me. I told you that they are all good... BURN is my favorite. And I like the BRAWN chocolate. Can you go bother someone else now?

Quotation Marks

It's all good. Good ingredients. Good flavors. I get some for free each month. Maybe more servings in BLAST?  I don't know. No names, right?

Quotation Marks

I have worked in formulating each of them. So maybe I'm biased. Here try this: should give you superpowers for 24 hours, or minutes. Not sure. None of subjects lived long enough.

Fun Fact

The word 'Labs' in Old School Labs is short for Labradors. All of our supplements are formulated and carefully dosed to meet a large dog's daily nutritional needs. Think we're making this up? You are correct.
