Receptor: A Lock On A Cell. The Peptide Is The Key. When The Right Key Fits The Right Lock, The Door Opens And Something Happens Inside.
GHRH: A Signal That Tells Your Body To Make Growth Hormone. Scientists Copy This Signal To Study How Growth Works.
GHRP: A Made-Up Signal That Does Something Like GHRH. Scientists Created It To Study Growth And See What Happens.
GHS-R1a (Ghrelin Receptor): A Special Lock That Listens For Growth Signals. When The Right Signal Comes, The Lock Opens And The Body Listens.
Secretagogue: Something That Tells Your Glands To Release Stuff. Like Pressing A Button That Makes A Machine Squirt Out Something.
IGF-1: A Signal Your Liver Makes When Growth Hormone Shows Up. It's Like The Messenger That Carries The Instruction 'Grow' To Other Cells.
GLP-1: A Signal Your Gut Makes After You Eat. It Tells Your Body: Make Insulin And Feel Full. Scientists Study This A Lot.
GIP: Another Signal From Your Gut After You Eat. It Also Says: Make Insulin. Works Together With GLP-1.
Incretin: Signals That Come From Your Gut And Tell Your Body To Make Insulin After You Eat. Like A Message: Nutrients Coming, Get Ready!
Amylin: A Signal Made Right Next To Insulin. It Says: You're Full, Stop Eating. Scientists Study How This Works.
Melanocortin: A Family Of Signals That Do Many Jobs. Make Color. Control Hunger. Scientists Study How They Talk To Cells.
MC1R: A Lock That Gets A Signal To Make Skin Color. It's In Your Pigment Cells. Changes This And You Get Different Colored Skin.
MC4R: A Lock In Your Brain That Controls Hunger. When This Gets A Signal, You Feel Full Or Hungry. Scientists Study This For Weight Research.
Telomerase: An Enzyme That Fixes The Ends Of Chromosomes. Like A Repair Worker That Stops Your DNA From Wearing Out. Studied For Anti-Aging.
Telomere: The Cap On The End Of Your DNA. Like The Plastic Tip On A Shoelace. It Gets Shorter Over Time. Short Telomeres Mean Old Cells.
Senolytic: Something That Clears Out Old Broken Cells. Like A Trash Truck For Bad Cells. Scientists Study It To Help People Age Better.
Senescence: When A Cell Gets Old And Stops Working. It's Still There But Doesn't Do Its Job Anymore. Scientists Study This Because It Happens During Aging.
Mitochondria: The Power Plant Of Your Cells. Like Little Batteries That Make Energy So Cells Can Work. Studied For Aging And Energy.
Cardiolipin: A Special Fat Found In Mitochondria. Like The Wire That Connects Everything. Important For Mitochondria To Work.
Mitophagy: When Your Cell Eats Its Own Broken Batteries. Like Recycling Old Mitochondria. Keeps Cells Clean And Healthy.
Angiogenesis: Growing New Blood Vessels. Like Building New Roads In A City So Blood Can Travel Better. Studied For Healing.
Pro-Angiogenic: Something That Helps Make New Blood Vessels. Like A Contractor That Builds Roads. Studied For Wound Healing.
Cytokine: A Tiny Message Sent Between Cells. Like A Text Message Your Cells Send Each Other. Tells Them What To Do.
Peptide Bioregulator: A Short Peptide That Tells A Part Of Your Body To Work Better. Like A Coach That Makes A Team Play Better.
Nootropic: Something Studied For Brain Power. Memory. Focus. Thinking Clearer. Scientists Research How These Work.
Anxiolytic: Something Studied To See If It Helps With Worry. Scientists Test It To Learn How It Works.
