Millions are running peptide self-experiments.
No one verifies what’s in the vial.
No one tracks what it does.
No one watches what happens when you stop.
Building Stack.
Coming soon
Your body is the most data-rich thing you own.
Every dose. Every lab. Every shift in how you feel.
Log your peptides, upload your labs, and earn STACK for every data point. Own what your body is already telling you.
Bodybuilders and biohackers have been self-experimenting with peptides like retatrutide for decades.
Pharma is just catching up.
Retatrutide is one of hundreds coming.
Someone has to track what actually works.
That's Stack.
Retatrutide phase 3 obesity trial just came out and the results are genuinely insane:
- 28.3% bodyweight lost on 12mg over 80 weeks
- 70.3 pounds on avg. or 31.9 kg
- 45.3% of patients hit 30%+ weight loss (this is bariatric surgery territory)
- 30.3% weight loss (85 lbs) at 104 weeks in higher-BMI patients
- 65.3% of 12mg patients dropped below the obesity BMI threshold
- 19% loss on 4mg over 80 weeks (47.2 lbs) with fewer dropouts than placebo (4.1% vs 4.9%)
- significant drops in blood pressure, triglycerides, non-HDL cholesterol, waist circumference, and hsCRP
- no cardiac or liver signals
Retatrutide is going to completely overshadow tirzepatide and semaglutide, and take the throne as the best-selling drug of all time.
