筋肉増強研究

IGF-1 LR3

Long-acting IGF-1 analogue with reduced IGFBP binding; half-life ~20 hours vs ~10 min for native IGF-1. Studied for satellite cell activation, skeletal muscle hypertrophy, and mTOR pathway research. Limited US availability — verify stock before ordering.

免疫向上研究

Thymosin Alpha-1

28-amino acid thymic peptide (Zadaxin® precursor) studied for T-cell maturation, NK cell activation, and vaccine adjuvant effects. Approved pharmaceutical in 35+ countries for hepatitis B/C. Most clinically validated peptide in this category.

睡眠改善研究

DSIP

Nonapeptide originally isolated from sleeping rabbit blood in 1977; studied for slow-wave sleep induction and EEG delta-wave modulation. Improves sleep architecture without sedation or dependence. Very limited US availability — custom synthesis required.

生殖健康研究

PT-141 (Bremelanotide)

Melanocortin receptor agonist (Bremelanotide/Vyleesi®) studied for central sexual arousal pathways via MC3R/MC4R in the hypothalamus. FDA-approved for hypoactive sexual desire disorder. Acts on desire (brain) not blood flow — distinct mechanism from PDE5 inhibitors.
