Optimize your Biology

The same systems thinking you apply to your business, applied to your body. GLP-1 protocols, peptide stacks, and the data to know what's actually working.

Track everything

InBody scans. Heart rate variability. Blood pressure. Wearables. I track more variables than most doctors ask about. If it's measurable, I measure it. No guessing, no bro science.

Is This You?

Done with advice designed for 25-year-olds? This is built for the 40+ crowd who's ready to put in the actual work and wants real data instead of a highlight reel.

NO SECRETS. NO PAYWALL. HERE'S WHAT YOU GET.

No supplement codes. No highlight reels. Here's what's actually here:

  • Email — honest protocol updates delivered straight to your inbox, no algorithm in the way
  • Video — real-time updates from the gym, the scale, and whatever I'm currently second-guessing
  • Blog — written deep dives on GLP-1s, peptides, and midlife recomp (coming soon)
  • Wellness consulting — personalized telehealth guidance through ActivTrim for those ready to build a real protocol (coming soon)
  • The stack — full transparency on what I'm running, how it's evolved, and what the data actually shows

MEET YOUR SUPER HERO

Heya! I'm Jeff Mendelson

I spent twenty years building marketing automation systems for businesses — funnels, CRMs, lead engines, the works. I was the Automation Superhero. I helped companies scale. I built a podcast that ran almost 400 episodes. I was good at it.

What I wasn't good at: my own biology. I was 285 pounds. My doctor was worried. The medications she'd been prescribing weren't working. And one day she looked at me and said, "I have to find a way to motivate you."

That was the origin story.
More than a year later, I'm down 80+ pounds on a GLP-1 and peptide protocol I've built, tested, and documented obsessively — because that's how my brain works. From marketing funnels to peptide protocols. Same obsession, different results.

I'm not trying to become Thor. I'm trying to become the enhanced version of myself. Captain America, not Black Widow. The science made me better — it didn't make me someone else.

I'm also the founder of Activtrim, a licensed telehealth wellness brand, and I consult privately with men who want to apply the same data-driven, no-nonsense approach to their biology that they use in their business.

Suit up.
