Pathophysiology from the genome to a person who notices
Disease is a stack: genome, transcriptome, proteome, metabolome, organelle, cell fate, tissue, organism. A peptide binds one node. The rest of the stack keeps running. CFTR, type 2 diabetes and a tendon as worked examples.

Recovery, GH pulses and the CJC / ipamorelin pair
Somatotrophs have two 'go' receptors. CJC without DAC is a slightly longer GHRH pulse. Ipamorelin is a selective ghrelin-receptor key that does not yank ACTH. Together they are the pair Bowers already showed is more than additive — not a gym protocol.

Reversing type 2 diabetes is a published result, not a slogan
The DiRECT trial put type 2 diabetes into remission by emptying the liver and pancreas of surplus fat. Very-low-calorie and very-low-carbohydrate programmes can both get you there. The mechanism isn't mystical.
The living cell

How peptides talk to cells: occupancy, amplification, arrestin
A peptide is a ligand. Most of the catalogue binds a GPCR on the cell surface: one occupancy, then enzymes make thousands of second messengers. That amplification is real, and it is not magic. Desensitisation is why more ligand is not more signal forever.

The living cell is a city, and you are 36 trillion of them
A 70 kg adult is on the order of 36 trillion cells, most of them red blood cells with no nucleus. A typical nucleated cell holds about ten billion proteins and two metres of DNA. The body recycles 40–60 kg of ATP a day. Those figures are published; this essay is what they mean.

From gene to protein: how a cell actually reads itself
DNA is transcribed, spliced, exported, translated and folded. A research peptide is the ligand at the end of that pipeline, already made. This essay is every machine in between — polymerases, spliceosome, ribosome — with the actual rates attached.

Mitochondria: the bacterium you kept, the genome it kept, the peptides it writes
You turn over 40–60 kg of ATP a day using a 16,569-base genome that still uses a bacterial genetic code. NAD+ is the hydride carrier Complex I spends. MOTS-c is a 16-mer translated from mitochondrial 12S rRNA — Lee, Kim, Cohen, 2015. That last sentence is real, and it is surprising.

Proteostasis: the cell that eats its own mistakes
Ten billion proteins, a 76-residue tag, a 2.5-megadalton proteasome, and autophagy for whole organelles. Hershko, Ciechanover and Rose, 2004. Ohsumi, 2016. DSIP is a sleep-isolation nonapeptide, not an autophagy ligand.

The nucleus, telomeres, and the four residues of Epithalon
Two metres of DNA folded into a nucleus a few micrometres across. TERT is off in most somatic cells on purpose. Epithalon is four residues, Ala-Glu-Asp-Gly, with a TERT and pineal literature. The machines are real. A large Western trial of telomere length in adults is not.

Membranes: a five-nanometre wall

The cell cycle, p53, and the decision to divide
G1, S, G2, M. Cyclins license kinases. Checkpoints can say no. p53 reads damage and writes p21, or apoptosis, or a senescence that will not reverse. Hayflick counted the doublings. A repair-peptide paper that cannot name which of those fates moved is still only a description.

How research peptides are made — and why HPLC actually matters
Solid-phase peptide synthesis builds a chain one residue at a time. HPLC then asks whether the main peak is what you think it is. ≥98% is not a slogan. It is a chromatogram.

Fatigue, cellular energy and the NAD+ / MOTS-c neighbourhood
NAD+ is the rechargeable chip every cell spends on fuel and DNA repair — and the pool shrinks with age. MOTS-c is a mitochondrial 16-mer sent out under metabolic stress. Two answers to 'I have no energy' that are not coffee.

Melanocortin circuits: pigment, appetite and PT-141
Melanotan II lights MC1, MC3, MC4 and MC5 — pigment plus the rest of the sheet. PT-141 is the free-acid cousin pointed at MC3 and MC4, the circuitry papers use for desire and energy, not skin colour. Same Arizona family. Different question.

GHRH and ghrelin mimetics: two keys on the same pituitary lock
Somatotrophs have two ‘go’ receptors — GHRHR (Gs–cAMP) and GHSR (Gq). Bowers showed that occupying both releases more GH than the sum of either. That is synergy as a receptor fact, not a smoothie.

Why peptides are the next chapter of medicine
More than a hundred peptide drugs are already approved. Insulin opened the century. GLP-1 agonists moved weight into bariatric territory. Oral tablets, biased agonists and triple ligands are the current argument.

Skin, collagen, hair — copper peptide, GLOW and the inflammation tail
GHK-Cu escorts copper into a fibroblast so collagen can be finished. GLOW puts that tripeptide in a cake with BPC-157, TB-500 and KPV. KPV on its own is the anti-inflammatory tail without the tan. Matrix literature, not a moisturiser.

Collagen powder is not a research peptide
Type I collagen is a thousand-residue triple helix. Industrial ‘collagen peptides’ are a 2–5 kDa hydrolysate of that helix — thousands of fragments, no single HPLC peak. GHK-Cu is three letters and a metal.

What are peptides? Short chains that run the body
Peptides are amino acids joined by peptide bonds — shorter than proteins, more specific than most small-molecule drugs. Insulin was the first. GLP-1 agonists are the current proof. The catalogue here is the same chemistry, labelled for research.

The pineal, melatonin and the 24-hour gene
The SCN is a transcription-translation loop that keeps ~24-hour time. The pineal converts its night signal into melatonin via AANAT. Peripheral clocks then decide when liver may make glucose. Aging flattens the peak.

Senescent cells refuse to die, and they talk too much
Hayflick watched fibroblasts stop dividing. Campisi named the SASP — the inflammatory letters those arrested cells keep sending. Clearing p16-high cells in mice (INK-ATTAC) delayed aging phenotypes. The pathology is accumulation, not the programme itself.

TB-500 and thymosin β4: repair is a cytoskeletal programme

NAD+: the currency of cellular time
NAD+ is nicotinamide adenine dinucleotide, the hydride coin Complex I wants oxidised and the stoichiometric substrate sirtuins, PARP1 and CD38 spend. Salvage through NAMPT is the kinetic bottleneck; the pool falls with age. Restoration in mice moves muscle, endothelium and stem-cell assays; human NR and NMN trials more often move the metabolome than a hard clinical endpoint. This essay is that topology, the named papers, and why a 1000 mg cake of lyophilised β-NAD+ is a laboratory reagent rather than an infusion.

IBS, gut lining and the two research peptides that sit on that literature

Appetite, body weight and the peptides that sit on metabolic literature
Retatrutide is the published triple-agonist chain LY3437943 — GLP-1, GIP and glucagon on one molecule. MOTS-c is a mitochondrial 16-mer that talks to AMPK. One is an incretin story. One is a fuel-gauge story. Neither is a diet.

Why peptides are freeze-dried — and what reconstitution actually is

The blood-brain barrier: why a dish is not a brain
