Whether you’re just beginning your wellness journey or deep into optimizing your health, navigating the world of hormone replacement therapy (HRT), weight loss programs, and cutting-edge peptide treatments can feel like learning a new language. At Radical Wellness, we believe in empowering our clients with knowledge. That’s why we’ve created this comprehensive glossary: a user-friendly guide to the terms, acronyms, and jargon you’re likely to encounter as you explore your personalized treatment plan.
From “adiponectin” to “zinc carnosine,” this A-to-Z reference will help demystify the technical language often used in wellness consultations, lab reports, and medical literature. Whether you’re curious about the difference between bioidentical and synthetic hormones, or trying to understand what BPC-157 actually does, this glossary is here to make complex ideas simpler—and help you feel more confident and informed every step of the way.

J
- JAK-STAT Pathway – A cellular signaling pathway activated by various hormones, including growth hormone.
- Juvenescence – The process of restoring youthful vitality, often a goal of peptide and hormone therapies.
K
- Kisspeptin – A peptide involved in initiating the hormonal cascade that leads to puberty and reproductive hormone production.
- Ketogenesis – The metabolic process of producing ketone bodies for energy, promoted by low-carb diets and certain peptides.
L
- L-Carnitine – A compound that helps transport fatty acids into mitochondria for energy production.
