Nelson Vergel is a chemical engineer who, by his own necessity, has become a leading advocate for sports nutrition, supplementation, hormone and therapies, and the promotion of wellness. His search for cutting-edge health  knowledge started when he was diagnosed with HIV over 25 years ago during a hopeless era. This life-threatening diagnosis propelled him to explore therapies to save his life and that of his peers by reviewing available literature, attending numerous health conferences, becoming an advocate member of NIH research committees, moderating online groups, and networking with many progressive clinicians. With his survival knowledge he has been able  to help people to lead a healthy life regardless of their health status or background. He is the author of "Testosterone: A Man's Guide" and co-author of the book "Built to Survive"; the founder of the nonprofit organizations Body Positive Wellness Clinic and Program for Wellness Restoration; the Nutrition and Exercise forum expert at TheBody.com; and a bilingual speaker on body composition, exercise, nutrition, supplementation, testosterone replacement, metabolic disorders, and medication side effect management. His latest project, ExcelMale.com, provides a trusted exchange platform for men's health in a moderated and curated environment.
