TB-500 (Thymosin Beta-4 Fragment)
TB-500 (Thymosin Beta-4 Fragment)
TB-500 is a synthetic analog of thymosin beta-4, a 43-amino-acid peptide naturally present in most tissues and cell types. It has been studied extensively in research contexts for its role in cell migration, blood vessel formation, and cellular differentiation pathways.
≥99% Pure
GHR-6 (Growth Hormone Releasing Hexapeptide)
GHR-6 (Growth Hormone Releasing Hexapeptide)
GHR-6 is a synthetic hexapeptide that acts as a growth hormone secretagogue in in vitro and animal studies. Researchers have utilized this peptide to investigate GH-axis signaling, appetite regulation pathways, and metabolic function in controlled laboratory settings.
≥97% Pure
IGF-1 LR3
IGF-1 LR3
IGF-1 LR3 is a modified form of insulin-like growth factor 1, featuring 83 amino acids with an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. This modification increases its half-life in research assays, making it useful for studying IGF-1 receptor activation and downstream signaling cascades.
≥99% Pure
Melanotan II
Melanotan II
Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It is used in research to investigate melanocortin receptor binding, pigmentation pathways, and related neuroendocrine signaling in animal and cell-based models.
≥98% Pure
PT-141 (Bremelanotide Fragment)
PT-141 (Bremelanotide Fragment)
PT-141 is a synthetic peptide derived from Melanotan II. It is a melanocortin receptor agonist studied in research for its interactions with MC3 and MC4 receptor subtypes. Laboratory investigations have focused on its role in central nervous system signaling pathways.
≥95% Pure
LL-37 (Cathelicidin Fragment)
LL-37 (Cathelicidin Fragment)
LL-37 is a 37-amino-acid antimicrobial peptide derived from the C-terminal domain of human cathelicidin (hCAP-18). It is widely used in microbiological and immunological research to study innate immune responses, membrane disruption mechanisms, and host defense peptide activity.
≥98% Pure
AOD-9604
AOD-9604
AOD-9604 is a synthetic peptide fragment corresponding to the C-terminal region (amino acids 177-191) of human growth hormone, with an added tyrosine at the N-terminus. It has been studied in research settings for its effects on lipid metabolism pathways without influencing IGF-1 levels in animal models.
