Selank cognitive performance learning memory attention tuftsin analog nootropic research Durham Peptides Canada Selank's most-discussed research applications are anxiolytic effects and stress response research — the two threads where Selank shares territory with established anxiolytic compounds while bringing its distinctive multi-mechanism profile. But there's a third major Selank research thread that's mechanistically distinct: cognitive performance research. The Russian-la

MOTS-c insulin sensitivity glucose homeostasis Lee 2015 Cell Metabolism research peptide Durham Peptides Canada MOTS-c's research literature has expanded substantially since its initial characterization, with prominent threads in AMPK mechanism research and exercise-mimetic research. But the foundational MOTS-c paper — Lee et al. 2015 in Cell Metabolism — was anchored on a different application angle entirely: insulin sensitivity and glucose homeostasis. The original characte

NAD+ mitochondrial research oxidative phosphorylation bioenergetics longevity Durham Peptides Canada NAD+'s longevity research thread is often centered on sirtuins — the NAD+-dependent enzyme family central to cellular aging biology. But sirtuins are only part of NAD+'s biological story, and arguably not even the most fundamental part. The more biologically foundational NAD+ research thread involves mitochondrial biology — the central organelle where NAD+ does its primary met

Semaglutide FLOW kidney research chronic kidney disease GLP-1 receptor Durham Peptides Canada Semaglutide's clinical research base now spans four major domains — type 2 diabetes (SUSTAIN), weight management (STEP), cardiovascular outcomes (SELECT), and now chronic kidney disease research (FLOW). The FLOW trial, published in New England Journal of Medicine in 2024 (Perkovic et al.), examined Semaglutide in adults with type 2 diabetes and chronic kidney disease, with kidney out

Tirzepatide SYNERGY-NASH MASH research dual agonist liver fibrosis Durham Peptides Canada Tirzepatide's clinical research base has expanded into a fourth major domain in 2024 — MASH (metabolic dysfunction-associated steatohepatitis) research, joining the established programs in type 2 diabetes (SURPASS), weight management (SURMOUNT), and sleep apnea (SURMOUNT-OSA). The SYNERGY-NASH trial, published in New England Journal of Medicine in 2024 (Loomba et al.), examined Tirzepati

Epithalon melatonin pineal gland circadian rhythm research peptide Khavinson Durham Peptides Canada Epithalon's research literature is most associated with telomerase activation — the molecular mechanism that occupies the bulk of current Western-language Epithalon research. But there's an older and arguably more biologically fundamental Epithalon research thread that often gets overlooked: the pineal origin and melatonin connection. Epithalon was originally identified from pi

5-Amino-1MQ muscle regeneration NNMT inhibitor aged muscle stem cells research Durham Peptides Canada 5-Amino-1MQ's most-developed application area is adipose tissue research (anchored on the Kraus 2014 Nature paper), but the compound has a second well-established research thread that's mechanistically distinct: muscle regeneration research. The 2019 paper by Neelakantan and colleagues in Biochemical Pharmacology established 5-Amino-1MQ specifically in aged muscle stem cell r

KLOW Blend components BPC-157 GHK-Cu TB-500 KPV four-peptide skin recovery research Durham Peptides Canada The KLOW Blend is Durham Peptides' most ambitious multi-component formulation — four distinct peptides engineered into a single co-lyophilized vial, addressing four different mechanisms in parallel for skin, anti-aging, and recovery research. Most coverage of KLOW treats it as the "GLOW + KPV" four-component combination, which is technically accurate but misses the more

TB-500 thymosin beta-4 cardiac research cardiomyocyte heart repair post-infarction Durham Peptides Canada TB-500's most-discussed research applications are tendon and ligament repair (the connective tissue thread), recovery research, and the Wolverine Stack combination with BPC-157. But there's a less-publicized research thread that's mechanistically distinct and clinically significant: cardiac research. The 2004 Nature paper by Bock-Marquette and colleagues established Thymo
