For laboratory research use only.
MK-677 Liquid is ibutamoren (MK-0677, L-163,191) in liquid form, for research protocols where measuring by volume is more practical than working with capsules. It’s made in the US and third-party lab tested: our manufacturer tests it twice, and we use an independent third-party lab for purity testing.
What MK-677 is
MK-677 is a small nonpeptide agonist of the growth hormone secretagogue receptor, GHS-R1a, the receptor that binds ghrelin. It’s often grouped with SARMs, but it has no androgen receptor activity. Its chemistry, the free base vs. mesylate question and the published research are covered on our MK-677 capsules page.
Liquid or capsules?
The compound is the same. Capsules give you a fixed 10mg per unit. The liquid is for protocols that call for volumetric measurement or dilution.
