Hgh Research Peptides

Recombinant human growth hormone (somatropin, 191 amino acids) is the direct-supply approach to GH research — distinct from secretagogue protocols that stimulate endogenous pituitary release. Where peptides like CJC-1295 and Ipamorelin preserve the natural pulsatile GH pattern, recombinant HGH delivers the hormone directly, producing a continuous exposure profile useful for protocols where pituitary function is compromised or absent.

Research areas span body-composition models, hepatic gene-expression research, IGF-1-axis investigation, and protocols comparing pulsatile versus continuous GH exposure. Different kit sizes accommodate varying protocol lengths. RetaLABS stocks research-grade HGH in 100IU (10IU × 10), 240IU (24IU × 10), and 400IU (40IU × 10) kits.
