Questions
Calendar age counts years; biological age estimates how old your body functions based on lifestyle, body composition, lab markers, and wearable data. Two 40-year-olds can differ by a decade biologically. Jevity's free two-minute assessment estimates your TrueAge and shows the highest-impact levers to lower it.
Peptides are short chains of amino acids that act as signaling molecules — collagen peptides for skin, GLP-1 receptor agonists for metabolic health, and others under active research. Cosmetic and nutritional peptides are available over the counter; therapeutic peptides require prescription and supervision by a licensed clinician. Jevity never sells prescription medication — we map your options and match you with verified, licensed clinics.
GLP-1 programs pair prescription medication with clinical oversight, nutrition planning, and progress monitoring. Eligibility is determined by a licensed clinician after evaluation. Jevity's assessment estimates whether you may be a candidate and connects you with supervised programs at verified clinics in Dubai, Toronto, Vancouver, and beyond.
The strongest levers are consistent: sleep quality, resistance training, protein-adequate nutrition, glucose stability, and stress regulation. Jevity turns these into a personalized protocol, tracks your TrueAge and daily FeelAge, and shows what's actually moving your numbers.
Yes — the UAE (Dubai, Abu Dhabi), Canada (Toronto, Vancouver), and the USA are our launch markets, with verified clinic networks in each. The free assessment and tracking app work worldwide.
In the current early-access build your data is stored on your own device — photos and check-ins never leave your browser. You can export everything as JSON or delete it permanently, anytime, in Settings.
