do a search on spectro and about 2 pages will come up on their stuff. I just got mine today, winny, deca and cyp.....they look top notch and very proffesional.....I know that my source is one of the best bro's around and after you read the posts in the search you will notice something......unlike some other underground labs....there is not a single negative complaint about them, I have not tried ttokkyo stuff but everyone who has tried both says that spectro is better quality.....more sterile etc.
