ALL IN PEPTIDE specializes in synthesizing complex peptides using a proprietary platform, with expertise in long, rare, hydrophobic, and modified peptide sequences.
A consolidated summary of published, peer-reviewed research — emphasizing preclinical and non-human studies — for every compound in the catalog. These are references to the scientific literature, not statements of efficacy for any product.
All compounds are supplied for laboratory research use only. Nothing here describes human use, dosing, or therapeutic benefit; findings in animal and cell models do not establish effects in humans.
Examined BPC-157 in a rat Achilles-tendon transection model paired with cultured tendon fibroblasts and identified dose-dependent activation of the focal adhesion kinase (FAK)–paxillin signaling cascade, which is involved in cell migration and survival.
Model: Sprague-Dawley rat Achilles model + cultured fibroblasts | Source
After sharp transection of the Achilles tendon from bone, BPC-157 improved functional, biomechanical (load-to-failure, stiffness), and histological healing (better collagen organization, more type-I collagen) versus controls, and offset corticosteroid-impaired healing.
Model: Rat tendon-to-bone healing | Source
A single intraperitoneal dose of BPC-157 was reported to improve the healing course of spinal-cord injury and support functional (tail) recovery relative to controls.
Model: Wistar rat spinal-cord-injury model | Source
cDNA-microarray work found growth-hormone receptor among the most up-regulated genes in BPC-157-treated tendon fibroblasts, with dose- and time-dependent increases at mRNA and protein levels; added growth hormone increased fibroblast proliferation.
Model: Rat Achilles tendon fibroblasts (in vitro) | Source
In a rat sciatic-nerve transection model, BPC-157 produced faster axonal regeneration (denser, larger fibers; thicker myelin), higher motor action potentials on EMG, and an improved sciatic functional index, with autotomy absent versus controls.
Model: Rat sciatic-nerve transection | Source
Synthesizes rat studies in which BPC-157 supported healing of numerous gastrointestinal anastomoses (esophagogastric, colocolonic, jejunoileal, ileoileal) and counteracted associated colitis, short-bowel, and sphincter dysfunction.
Model: Rat gastrointestinal anastomosis models | Source
BPC-157 counteracted combined gastrointestinal, liver, and brain toxicity induced by the NSAID diclofenac in rats, whether given intraperitoneally or orally in drinking water — consistent with its cytoprotective profile.
Model: Rat NSAID-toxicity model | Source
Research stage: Evidence base is overwhelmingly preclinical (primarily rat models); robust human efficacy trials have not been completed.
A fragment of the regenerative protein Thymosin β-4, studied for its role in cell migration and angiogenesis. Preclinical work spans cardiac-repair, wound-healing, and hair-follicle models.
Mechanism: Corresponds to the actin-binding region (LKKTETQ) of Thymosin Beta-4, a regenerative protein in most cell types. The literature links it to G-actin regulation, cell migration, and angiogenesis (VEGF, HIF-1α).
A landmark study reporting that Thymosin Beta-4 activated integrin-linked kinase, promoted cardiac cell migration and survival, and supported cardiac repair after simulated myocardial infarction (reducing infarct size in mice).
Model: Mouse myocardial-infarction model | Source
Established that Thymosin Beta-4 stimulates directed migration of human umbilical-vein endothelial cells — the mechanistic foundation for subsequent angiogenesis research.
Model: Human endothelial cell culture (in vitro) | Source
Model: Rat / mouse wound and ocular models | Source
Using Tβ4-overexpressing and knockout mice, hair regrew faster in overexpressing mice (more follicles entering anagen, more shafts) and slower in knockouts, with elevated VEGF and P38/ERK/AKT signaling — evidence that normal Tβ4 is required for typical hair cycling.
Model: Transgenic and knockout mouse hair model | Source
Research stage: Evidence base is overwhelmingly preclinical (primarily rat models); robust human efficacy trials have not been completed.
Mechanism: A naturally occurring copper-binding tripeptide that declines with age. Studied extensively for collagen/elastin synthesis, extracellular-matrix remodeling, and broad gene-expression modulation.
GHK-Cu stimulated collagen synthesis in cultured fibroblasts at concentrations as low as 10⁻¹² M, peaking near 10⁻⁹ M, independent of changes in cell number.
Model: Cultured fibroblasts (in vitro) | Source
In a rat wound-chamber model, GHK-Cu produced concentration-dependent increases in type-I and type-III collagen mRNA (about twice the stimulation of non-collagen proteins) without corresponding TGF-beta mRNA increases.
Model: Rat wound-chamber model | Source
Profiling of human fibroblast cultures found GHK significantly modulated expression of roughly 4,699 genes — up-regulating tissue-repair and remodeling genes while down-regulating genes tied to inflammation and fibrosis.
Model: Human fibroblast cultures (in vitro) | Source
A review synthesizing the gene-level data, including Broad Institute Connectivity-Map findings that GHK-Cu influences DNA-repair and tissue-remodeling gene programs.
Model: Review of preclinical / gene-expression data | Source
A multi-institution study found GHK reversed the gene-expression signature of emphysema/COPD across 127 disease-associated genes; in vitro, GHK restored the ability of COPD-patient lung fibroblasts to contract and remodel collagen gel to near-normal levels.
Model: Human lung fibroblasts + gene-expression analysis | Source
Research stage: Deep preclinical and mechanistic base; limited controlled human data exists in dermatology (topical), outside the research-use context.
