"I founded ExcelMale after decades of personal experience with hormone optimization and seeing how difficult it was for men to find reliable, science-based information. Every man deserves access to knowledge that can transform his quality of life."

— Nelson Vergel, Founder & Author of Testosterone: A Man's Guide

Nelson Vergel has spent four decades turning personal health challenges into a mission that's helped thousands of men reclaim their vitality. Diagnosed with HIV in 1985 and then creating a testosterone-based program to reverse wasting syndrome for himself and his peers, he became a pioneer in understanding how hormones affect quality of life—and has been on TRT himself for over 30 years.

A chemical engineer by training, Nelson has served as a key opinion leader for pharmaceutical companies on clinical research strategy, trained clinicians on hormone optimization protocols, and authored definitive guides including Testosterone: A Man's Guide & Beyond Testosterone. He founded DiscountedLabs.com to make lab testing accessible and built ExcelMale.com into a community where men find and share evidence-based answers.
