为您的研究工作提供简洁、易引用的事实——先给出定义，再介绍作用机制、半衰期、典型研究剂量及可逐字引用的摘要。
BPC-157 is a 15-amino-acid pentadecapeptide derived from human gastric juice with documented angiogenic and tendon-repair activity in rodent models.
BPC-157, originally isolated from gastric juice (Sikiric et al., 1991), shows reproducible tendon-repair acceleration in rat Achilles models at 10 µg/kg.
IGF-1 LR3 is a 83-residue insulin-like growth factor analogue with an N-terminal Arg substitution that extends serum half-life roughly 12-fold versus native IGF-1.
IGF-1 LR3 binds IGFBPs ~5× less avidly than wild-type IGF-1, leaving a higher free fraction and a measured half-life near 20 hours in human serum.
Retatrutide (LY3437943) is a triple-agonist peptide co-activating GLP-1, GIP, and glucagon receptors, the first triagonist to advance into Phase 3 obesity trials.
Retatrutide produced 24.2% mean placebo-adjusted weight loss at 48 weeks in the Phase 2 trial (Jastreboff et al., NEJM 2023), the largest observed for any incretin to date.
Ipamorelin is a selective ghrelin/GHS-R1a agonist pentapeptide that stimulates pulsatile growth-hormone release without elevating cortisol or prolactin.
Ipamorelin demonstrates the cleanest selectivity profile among ghrelin mimetics, with no measurable effect on prolactin or cortisol at GH-active doses.
Melanotan II (MT-2) is a synthetic alpha-MSH analogue activating MC1R/MC3R/MC4R/MC5R; the MC1R activation drives the melanogenesis pigmentation effect studied in dermatology models.
MT-2 retains nanomolar affinity at MC1R, MC3R, MC4R and MC5R, producing pigmentation, appetite suppression and pro-erectile responses in concert.
GHK-Cu (copper tripeptide-1) is a glycyl-histidyl-lysine sequence chelated to Cu²⁺, with documented gene-modulating activity across 4 192 human genes (Pickart 2008).
GHK-Cu shifted the expression of 4 192 human genes by ≥50% in a 2008 microarray study by Pickart, the broadest known transcriptomic effect of a tripeptide.
TB-500 is a synthetic 17-amino-acid fragment (residues 17–23 of native Thymosin Beta-4), representing the actin-binding region responsible for cell migration during repair.
TB-500 contains the LKKTET actin-binding motif (residues 17–23 of Thymosin Beta-4) that drives stem-cell migration to injury sites in vivo.
Tesamorelin is a 44-amino-acid trans-3-hexenoyl-modified GHRH analogue, the only GHRH analogue with FDA approval (HIV-associated lipodystrophy, 2010).
Tesamorelin reduces visceral adipose tissue by 18% at 26 weeks in HIV-lipodystrophy patients (Falutz NEJM 2007), the only GHRH analogue cleared by the FDA.
MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded in the 12S rRNA region, regulating insulin sensitivity via AMPK activation.
MOTS-c is encoded within the mitochondrial 12S rRNA gene (Lee et al., Cell Metabolism 2015) and signals from mitochondria to the nucleus to regulate insulin sensitivity.
Semax is a 7-amino-acid synthetic ACTH(4-7) analogue developed at the Russian Academy of Sciences, used in BDNF-modulation and stroke-recovery research.
Semax is included on the Russian Vital and Essential Drugs list and is studied for stroke recovery and ADHD; it elevates hippocampal BDNF by ~1.5× in murine models.
