About
About Juan C. Zuniga Jr.
Juan C. Zuniga Jr., known online as thezunigas, is a peptide and biohacking educator who publishes three research-driven videos a day on Instagram, and the coach behind The Peptide Lab.
His breakdowns on GHK-Cu, retatrutide and glutathione are among the most-watched peptide content on his channels, each one built on the published studies rather than marketing claims.
Peptide education
Peptides are everywhere on social media, and the conversation is often confusing. Juan publishes three short videos a day on Instagram (@thezunigas), with clips on TikTok, explaining what individual peptides are, how they work and what the research shows.
How I approach it
- Research first: every breakdown starts with the published studies, from mechanism to human trials.
- Plain language: complex science, explained so you can actually use it.
- Real context: where a compound stands today, from lab data to approved medicine.

Off camera
Juan is also a runner. Running is the lens for a lot of what he covers: how to train consistently, recover well and stay healthy for decades.
