Tissue & Repair Research
BPC-157 — Body Protection Compound-157
One of the most studied peptides in preclinical research, with over 500 published papers spanning multiple organ systems.
Key Published Findings
- A 2025 systematic review of 36 studies (1993–2024) found BPC-157 enhanced growth hormone receptor expression, promoted angiogenesis, and reduced inflammatory cytokines in preclinical musculoskeletal injury models. PMID: 40756949
- A 2025 scoping review reported BPC-157 demonstrated regenerative and cytoprotective effects in preclinical studies across muscle, tendon, ligament, and bone injury models, with no adverse effects reported in preclinical safety evaluations. PMID: 40789979
- Preclinical safety evaluation found no minimum toxic dose, no lethal dose, and no teratogenic, genotoxic, anaphylactic, or local toxic effects (Xu et al., 2020).
Note: Only three published human pilot studies exist as of 2025. Rigorous clinical trials are lacking. BPC-157 should be considered investigational.

Tissue & Repair Research
TB-500 — Thymosin Beta-4
A naturally occurring peptide present in virtually all human and animal cells, studied extensively since the late 1990s.
Key Published Findings
- Thymosin Beta-4 increased re-epithelialization by 42% at 4 days and 61% at 7 days post-wounding compared to saline controls, with stimulated keratinocyte migration at concentrations as low as 10 pg (Malinda et al., 1999). PMID: 10469335
- A 2012 review described Thymosin Beta-4 as a "multi-functional regenerative peptide" with advances providing the scientific foundation for ongoing clinical trials in dermal wounds, corneal injuries, and cardiac tissue regeneration. PMID: 22074294
- Phase I and Phase II clinical trials have shown a high safety profile, anticipating that TB-4 will be safe at applied doses for broad clinical applications (Kleinman & Sosne, 2021). PMC: 8228050

Cellular & Metabolic Research
GHK-Cu — Copper Peptide
A naturally occurring copper complex first discovered in 1973, studied across 80+ published research papers for regenerative and protective actions.
Key Published Findings
- A 2018 review described GHK-Cu's regenerative and protective actions including improved tissue repair in skin, lung, bone, liver, and stomach lining, plus multiple anti-cancer and anti-inflammatory activities, DNA repair, and proteasome activation. PMID: 29986520
- Gene profiling studies revealed GHK-Cu modulates a large number of human genes, suggesting it may belong to a class of epigenetic modifiers capable of broad protective and restorative actions (Pickart et al., 2012). PMC: 3359723
- A 2020 review found GHK-Cu can partially reverse cognitive impairment in aging mice by targeting anti-inflammatory and epigenetic pathways, providing rationale for further investigation in aging studies. PMID: 35083444

Growth Hormone Research
Ipamorelin — Selective GH Secretagogue
Described in the literature as "the first selective growth hormone secretagogue" due to its unique specificity profile.
Key Published Findings
- The original 1998 characterization study found Ipamorelin released GH with potency comparable to GHRP-6 but — unlike other secretagogues — did not significantly affect ACTH or cortisol levels, even at doses 200-fold higher than the GH-releasing ED50. PMID: 9849822
- In adult rat models, Ipamorelin counteracted glucocorticoid-induced decreases in bone formation and increased maximum tetanic muscle tension, with periosteal bone formation rate increasing four-fold (Svensson et al., 2001). PMID: 11735244
- A 2020 review of growth hormone secretagogues identified Ipamorelin as a potent GH and IGF-1 stimulator that can improve body composition in preclinical models. PMC: 7108996

Cellular & Metabolic Research
MOTS-c — Mitochondrial ORF of 12S rRNA Type-C
A mitochondrial-derived peptide discovered in 2015, now the subject of growing research interest in metabolic homeostasis and aging.
Key Published Findings
- A 2023 review described MOTS-c's role in glucose metabolism in skeletal muscle and its potential relevance to diabetes, obesity, and aging research. The protein is transferred to the nucleus during metabolic stress and directs gene expression to promote cellular balance. PMID: 36761202
- MOTS-c promoted mitochondrial homeostasis in aged mesenchymal stem cells by activating AMPK and inhibiting mTORC1, with the mitochondrial state of treated old cells becoming more similar to young cells (Kim et al., 2021). PMID: 33639272
- A 2025 study found MOTS-c levels decrease with aging in pancreatic islet cells, and MOTS-c treatment improved pancreatic islet senescence and glucose intolerance in mouse models. PMID: 40855115

Neuropeptide Research
Semax / NA-Semax — Neuropeptide
Originally developed at the Institute of Molecular Genetics of the Russian Academy of Sciences as a synthetic ACTH(4-7) analog.
Key Published Findings
- Semax stimulated BDNF expression in different areas of the rat brain in vivo, a key neurotrophic factor investigated for its role in neuroplasticity and cognitive function (Dolotov et al., 2003). PMID: 14556513
- In rat brain focal ischemia, Semax influenced the expression of genes that promote the formation and functioning of the vascular system, with multidirectional effects on NGF and BDNF gene expression (Agapova et al., 2008). PMID: 19662538
- In conditions of rat brain focal ischemia, Semax affected the expression of genes related to the immune and vascular systems (Genbank study, 2014). PMC: 3987924
