Our History

Bryan Haycock, author and founder of the Hypertrophy-Specific Training (HST) method and Hypertrophy-Specific Nutrition (HSN), began lifting weights in 1978. Over the last 23 years he has incorporated his passion for bodybuilding into his education as a physiologist and career as a writer and consultant for the sport supplement industry.

In 1998 Bryan was invited to write and work as editor-in-chief for the online magazine Mesomorphosis, founded by Millard Baker. The magazine experienced rapid growth in popularity and set a new standard for scientific accuracy in fitness publications. In July 2000, Mesomorphosis changed its name to ThinkMuscle. With the new name, ThinkMuscle began offering a newsletter that through word of mouth has grown to nearly 25,000 enthusiastic subscribers in only two years.

With Bryan in the editorial driver's seat, ThinkMuscle has grown to world-renowned status. In 2001 EAS™, the second largest sports supplement company in the industry declared ThinkMuscle as "one of the great destination sites of the industry" and advised readers to be able to recognize the name "Bryan Haycock" as he "produce[s] some of the best information this industry has to offer." Currently, more than 2,000 new subscribers sign up for Bryan's newsletter each month.

In October of 2000, Bryan wrote a short unassuming article describing a method of training that research had indicated would lead to the greatest degree of muscle growth. He called it Hypertrophy-Specific Training. Although he and his clients had been using this method for sometime, he had never shared it publicly. Slowly, after publishing the article in the ThinkMuscle newsletter, people began to apply HST to their own training, and the mail started flooding in.

In late 2001, frustrated with currently available supplements, Bryan recognized the opportunity to better meet the needs of his peers working professionally in the health/fitness industry by creating a line of ultra high quality products that could be used by him and other professionals. Seeing the consumers' growing distrust of supplement companies and their aggressive marketing, he decided to extend the availability of his exclusive line to his readers.

In 2002 this, the Official Hypertrophy-Specific website, was launched to be the industries trusted source for information on diet, training and supplementation.
