MK-677 15mg – 50 Tablets
$ 56.10
- MK-677, commonly known as Ibutamoren, is grouped within the SARM research category in product naming convention despite having no androgen receptor activity whatsoever. Tt is an orally bioavailable growth hormone secretagogue that activates the same GHS-R1a receptor targeted by injectable GHRPs like GHRP-2, Ipamorelin, and Hexarelin, but does so through an oral tablet rather than an injectable peptide. F40 Biotech’s formulation delivers 15mg per tablet in a 50 count format, consistent with the concentration most commonly referenced in GH secretagogue research literature. MK-677’s mechanism mirrors the GHS-R1a agonist GHRPs in CSD’s peptide range, directly stimulating pituitary somatotroph cells while suppressing hypothalamic somatostatin tone, producing GH pulse amplitude increases through the same dual mechanism as Ipamorelin and GHRP-2. What distinguishes MK-677 from every injectable GHRP is its oral bioavailability and exceptionally long half-life of approximately 24 hours. Supporting once daily oral administration where injectable GHRPs require subcutaneous administration one or more times daily due to their much shorter half-lives. This pharmacokinetic profile has made MK-677 one of the most extensively studied oral GH secretagogues, with documented clinical research examining sustained GH and IGF-1 elevation from consistent daily oral dosing rather than the discrete pulse pattern produced by short acting injectable GHRPs. MK-677’s research literature includes clinical investigation into elderly populations examining sustained GH/IGF-1 axis stimulation for sarcopenia and frailty research, alongside documented effects on sleep architecture, appetite stimulation through ghrelin receptor activity, and bone mineral density. Its ghrelin receptor activation additionally produces appetite stimulating effects comparable to GHRP-6’s pronounced orexigenic activity within CSD’s GHRP range. Both compounds share the same receptor mediated appetite stimulation mechanism, with MK-677’s oral route and extended half-life producing more sustained appetite effects than GHRP-6’s shorter acting injectable profile.
