    Triple Monoamine Reuptake Inhibitor

    A small molecule that blocks the reuptake of dopamine, norepinephrine, and serotonin at once — a triple-monoamine mechanism.

    Tesofensine (NS-2330) raises the synaptic availability of all three monoamines, a broader central mechanism than single-target agents, and is studied extensively in appetite-regulation and metabolic research. Notable for an unusually long ~220-hour half-life. Supplied as a pre-mixed 30 mL solution at 0.5 mg/mL. Research-grade, HPLC verified, and lot-verified.

    Long-Acting IGF-1 Analog

    A recombinant IGF-1 analog engineered to resist binding proteins — same receptor signal, far longer reach.

    IGF-1 LR3 (Long R3 IGF-1) carries an Arg-3 substitution and a 13-residue N-terminal extension that cut its affinity for IGF-binding proteins, giving a ~20–30 hour half-life and roughly three times the potency of native IGF-1 while retaining full IGF-1R activity (PI3K/Akt and MAPK). Research-grade, HPLC verified, and lot-verified.

    Reproductive-Axis Neuropeptide

    A decapeptide agonist of the KISS1R (GPR54) receptor — the most upstream known regulator of the reproductive axis.

    Kisspeptin-10 (Metastin 45–54) sits one tier above every hormone it commands: it activates hypothalamic GnRH neurons, which drive the pituitary release of LH and FSH. A leading subject in fertility, puberty, and neuroendocrine research. Research-grade, HPLC verified, and lot-verified.
