Tissue-repair signaling research
Name: Body Protection Compound 157; a 15-amino-acid peptide.
Research focus: tendon cells, connective tissue and gastrointestinal injury.
Evidence: mainly cell and animal experiments; small human reports.
GHK-Cu
Copper peptide and connective tissue
GHK: glycine-histidine-lysine, a three-amino-acid peptide.
Cu: copper bound to the peptide in a coordination complex.
Research focus: collagen production and wound biology.
Ipamorelin
Main effect: stimulates GH release; human hormone-response studies exist.
Selectivity: early experiments found relatively selective GH stimulation.
Distinct pathway: acts through a different receptor from GHRH analogs.
Gut research: studied for motility after surgery; the trial found no significant
efficacy benefit.
Pairing rationale: GHRH-pathway stimulation may amplify GH release.
Safety: chronic-use data are limited; serious IV-trial events do not alone
establish causation.
KLOW – 80mg
Blend composition study card
Product name: KLOW; the catalog lists 80 mg total.
Total quantity: combined mass, not the amount of each ingredient.
Compos
Melanotan II
Pigmentation and sexual-response signaling
Also called MT-2; a synthetic cyclic melanocortin peptide.
Related to alpha-MSH, a melanocyte-stimulating hormone.
Human observations: pigmentation and erectile-response effects in small
studies.
MOTS-c
Mitochondrial metabolic signaling
Identity: a 16-amino-acid mitochondrial-derived peptide.
Origin: associated with a reading frame within mitochondrial 12S rRNA.
Research focus: insulin sensitivity and metabolic stress responses.
NAD+
Coenzyme for redox and enzyme reactions
Name: nicotinamide adenine dinucleotide; not a peptide.
NAD+ is the oxidized form; NADH is the reduced form.
Biological role: transfers electrons and supports cellular enzyme reactions.
PT-141
Bremelanotide and sexual-desire signaling
Identity: cyclic melanocortin receptor agonist.
Approved Vyleesi use: defined acquired, generalized low-desire disorder.
Clinical population: premenopausal women meeting the indication criteria.
Retatrutide – 10mg, 20mg and 30mg Incretin actions: engage pathways involved in appetite and glucose regulation. Glucagon action: adds a distinct metabolic signal to the receptor profile. Weight findings: substantial mean weight reduction in controlled human trials. Liver findings: a randomized substudy measured reduced liver fat. Side effects: GI symptoms, increased heart rate and abnormal…
Selank
Anxiety and neurotransmission research
Identity: seven-amino-acid peptide based on tuftsin with a Pro-Gly-Pro
extension.
Research focus: anxiety-related symptoms and neurotransmission.
Evidence: small human comparative studies plus experimental work.
Semax
Neurotrophin and brain-ischemia research
Identity: ACTH(4-7)-Pro-Gly-Pro, a seven-amino-acid peptide.
Research focus: neurological responses to inadequate brain blood supply.
Evidence: experimental studies and limited clinical stroke reports.
TB-500
Thymosin beta-4 fragment research
Identity: FDA uses TB-500 for the seven-amino-acid fragment LKKTETQ.
Research focus: wound repair, cell movement and angiog
Tesamorelin
GHRH analog with visceral-fat evidence
Identity: modified 44-amino-acid peptide that stimulates GH release.
Approved Egrifta use: excess abdominal fat in HIV-associated
lipodystrophy.
Visceral fat surrounds organs; subcutaneous fat lies beneath the skin.
Tirzepatide
Dual GIP and GLP-1 receptor agonist
Identity: modified 39-amino-acid peptide; two receptor targets.
Human benefits: improved glucose control and substantial trial weight loss.
Approved products: Mounjaro and Zepbound for specified indications.
