Peptides are how your body talks to itself. We restore the signals you've been making your whole life, at the levels you used to make them.
Proteins run huge, hundreds or thousands of amino acids strung together. A peptide is much shorter, usually 2–50 amino acids. That smaller size is what makes them good at one thing: carrying a signal.
Every peptide in your body has a specific job: regulate appetite, repair tissue, release a hormone, modulate the immune system. They're how cells communicate with each other in real time.
Therapeutic peptides are precision copies (or close analogs) of the same signals your body already uses, dosed at the levels needed to nudge a specific outcome.
Your stomach is built to demolish proteins. That's literally its job. Acid and digestive enzymes (pepsin, trypsin) tear peptide bonds apart in minutes, so a peptide you swallow rarely survives long enough to do anything. A subcutaneous injection skips the digestive system and puts the signal straight into your bloodstream.
Peptide hits the stomach, gets pulled apart by acid and proteases before any signal reaches the bloodstream.
Peptide goes into fat just below the skin, absorbs into capillaries, and enters circulation intact within minutes.
Hover over either card to speed up the flow.
Once a peptide reaches its target tissue, it locks into a specific receptor the way a key fits one lock. Binding flips a switch on the cell's surface that triggers a signaling cascade inside. Your own cells handle it from there: change gene expression, release a hormone, repair tissue. The peptide is only the message.
Peptide circulates in the bloodstream and finds tissue expressing its matching receptor: pituitary, hypothalamus, gut, muscle.
It locks into the receptor's binding pocket. The geometry is exact, so a peptide only fits the receptor it was shaped for.
Binding triggers second-messenger pathways (cAMP, PKA, MAPK) that change gene expression and release hormones.
Each protocol targets a different receptor system. Tap any peptide below to watch its mechanism animate: the receptor it binds, the hormone it moves, and what changes downstream.
Semaglutide is a near-copy of GLP-1, the gut hormone your intestines release after a meal. It's been modified to resist enzymatic breakdown, so it survives a full week in circulation against the natural hormone's 2 minutes.
It binds GLP-1 receptors in three places: the hypothalamus (reduces hunger signaling), the stomach (slows gastric emptying), and the pancreas (sharpens glucose-stimulated insulin response).
BPC-157 is a 15-amino-acid fragment derived from a protein found in human gastric juice. It's the body's own repair signal for the gut lining, given systemically here to speed healing in other tissues too.
It upregulates VEGFR2 and the nitric oxide pathway, which accelerates angiogenesis (new blood vessel formation). Better blood supply to injured tissue means faster delivery of nutrients, oxygen, and growth factors, and faster healing in tendon, ligament, gut, and muscle.
This is a two-peptide stack that tells your pituitary gland to make more of your own growth hormone, instead of injecting exogenous GH directly.
CJC-1295 mimics GHRH (growth-hormone-releasing hormone). Ipamorelin mimics ghrelin, hitting a separate receptor on the pituitary. Together they trigger a stronger, cleaner GH pulse than either does alone, without the cortisol and prolactin spikes older GH-releasing peptides caused.
Your body still sets the release pattern: overnight pulses, aligned to sleep.
NAD+ is a coenzyme rather than a peptide, but it's delivered the same way and runs alongside peptide protocols. Levels drop about 50% between age 40 and 60. Replacing it restores the activity of sirtuins and PARPs, the enzymes that maintain mitochondrial function and repair DNA.
Epitalon is a 4-amino-acid peptide that activates telomerase, the enzyme that maintains the protective caps on your chromosomes. In trials it normalizes circadian rhythm, melatonin production, and several markers of cellular aging.
Same peptide family, different goal, different hormone fingerprint. Drag the timeline to watch each peptide's effects build over weeks of protocol.
Net effect: appetite-control hormones go up, hunger and glucose volatility come down. Insulin sensitivity rises as fat mass drops.
Directional changes only. Individual response varies, and real protocols include monthly lab work.
