Merck designed it in the 1990s as a non-peptide molecule that reproduces the action of the growth hormone releasing peptides while remaining active when swallowed. It is not a SARM and does not target the androgen receptor. It activates the ghrelin receptor, GHS-R1a, which signals the pituitary to release growth hormone in pulses; the liver answers with more insulin-like growth factor 1 (IGF-1).\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eIdentifier\u003c\/th\u003e\n\u003cth\u003eIbutamoren (free base)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAS number\u003c\/td\u003e\n\u003ctd\u003e159634-47-6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolecular formula\u003c\/td\u003e\n\u003ctd\u003eC27H36N4O5S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolecular weight\u003c\/td\u003e\n\u003ctd\u003e528.7 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInChIKey\u003c\/td\u003e\n\u003ctd\u003eUMUPQWIGCOZEOY-JOCHJYFZSA-N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePubChem CID\u003c\/td\u003e\n\u003ctd\u003e178024\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThese PubChem values describe the free base.

In a 1996 placebo-controlled study, 32 healthy volunteers aged 64 to 81 were assigned to placebo or once-daily oral ibutamoren for two and four weeks. Growth hormone rose because existing pulses grew larger, not more frequent, and at the highest of the three daily amounts tested, IGF-1 reached the range typical of young adults. Fasting glucose and prolactin also rose.\u003c\/p\u003e\n\u003cp\u003eThe longest trial, published in 2008, randomised 65 healthy adults aged 60 to 81. Over the first year, fat-free mass rose by 1.1 kg with ibutamoren and fell by 0.5 kg with placebo, but strength and function did not change, total fat mass and abdominal visceral fat did not differ, and body weight and limb fat rose more than with placebo. Adverse findings included increased appetite, mild transient swelling of the lower legs, muscle pain, a 0.3 mmol\/L rise in fasting glucose, reduced insulin sensitivity and higher cortisol. The authors judged the study too small and short to assess function.\u003c\/p\u003e\n\u003cp\u003eIbutamoren mesylate was also tested in a 2011 phase IIb trial in 123 older people recovering from hip fracture. IGF-1 went up and gait speed improved, while stair-climbing power and several other functional measures did not. Congestive heart failure in a small number of patients led to the trial being halted early, and the investigators concluded that the adverse-effect profile was unfavourable in that group. Merck did not take ibutamoren to approval. These findings describe study participants and are not claims about this product.\u003c\/p\u003e\n\u003ch2\u003eThis listing\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompound: MK-677 (Ibutamoren)\u003c\/li\u003e\n\u003cli\u003eBrand and manufacturer: Yakka Strength\u003c\/li\u003e\n\u003cli\u003eForm: capsules\u003c\/li\u003e\n\u003cli\u003ePack size: 60 capsules\u003c\/li\u003e\n\u003cli\u003eStrength per capsule: not stated in the product information we hold\u003c\/li\u003e\n\u003cli\u003eTotal per pack: cannot be calculated without a stated strength\u003c\/li\u003e\n\u003cli\u003eIntended use: laboratory research only, not for human consumption\u003c\/li\u003e\n\u003cli\u003eSold to adults aged 18 and over\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith no stated strength, neither milligrams per pack nor cost per milligram can be worked out, so this pack cannot be ranked against brands that print a figure (method: \u003ca href=\"\/blogs\/news\/price-per-mg-compare-sarms-peptides\"\u003eprice per milligram\u003c\/a\u003e).

Without an MHRA marketing authorisation it cannot be marketed as a medicine, and as it is neither an authorised food supplement nor an authorised novel food, it cannot be marketed as food. It cannot lawfully be sold for human consumption. That leaves supply as a research compound for laboratory work: the only way Free Muscle lists it, and only to buyers aged 18 or over. In sport it is banned at all times (see detection, below), and buyers are responsible for the rules that apply to them, including any anti-doping code.

FreeMuscle LTD is a UK company in Scunthorpe, the manufacturer is named, and every order goes by free tracked UK delivery in plain packaging. Orders placed before 2pm Monday to Friday are processed the same working day, EU delivery takes 3-7 working days, and unopened items can be returned within 30 days. The certificate point depends on the batch, because a Yakka Strength COA is shown only where the manufacturer supplies one. The strength point is not met: the product information we hold gives no figure. Price searches meet the same limit: prices change and appear on the listing itself, and a fair comparison is price per milligram, which needs a stated strength.

Peptide secretagogues are in the opposite position (see \u003ca href=\"\/blogs\/news\/do-oral-peptides-work\"\u003edo oral peptides work\u003c\/a\u003e).

Section S2.2.4 (growth hormone releasing factors) names \"ibutamoren (MK-677)\" as an example of a growth hormone secretagogue, and every substance in section S2 is non-Specified.

Record when the pack was first opened alongside its batch number. Handle it as a laboratory reagent: gloves for opened capsules or loose powder, away from food and drink, out of reach of children and animals, any removed portion labelled with compound, batch and date, and waste disposed of as chemical waste, not in household bins or drains. Never decant capsules into an unlabelled container; the batch number on the original pack is the only link to a certificate.\u003c\/p\u003e\n\u003ch2\u003eGlossary\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth hormone secretagogue\u003c\/strong\u003e: the drug class ibutamoren belongs to, defined by causing the pituitary to secrete more of its own growth hormone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGHS-R1a\u003c\/strong\u003e: the receptor through which the stomach hormone ghrelin acts; ibutamoren and ipamorelin both activate it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIGF-1\u003c\/strong\u003e: insulin-like growth factor 1, a hormone whose blood level tracks growth hormone output, most of it produced by the liver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulsatile secretion\u003c\/strong\u003e: the pattern in which growth hormone leaves the pituitary as a series of peaks, not a constant flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIbutamoren mesylate\u003c\/strong\u003e: the methanesulfonic acid salt of ibutamoren, heavier than the free base.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree base\u003c\/strong\u003e: the molecule without a salt partner.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFat-free mass\u003c\/strong\u003e: body mass minus fat, including water, so it rises with fluid retention as well as tissue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOedema\u003c\/strong\u003e: swelling from fluid collecting in tissues.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulin sensitivity\u003c\/strong\u003e: the degree to which muscle, liver and fat respond to insulin; lower sensitivity means glucose is cleared from the blood less readily.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLC-MS\u003c\/strong\u003e: a liquid chromatograph feeding a mass spectrometer, so each separated component is also weighed as ions; the firmer identity test.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003em\/z\u003c\/strong\u003e: mass-to-charge ratio, the value a mass spectrometer reports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertificate of analysis (COA)\u003c\/strong\u003e: one batch's laboratory results (identity, purity and content where measured), dated and carrying that batch's number.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRelated\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/mk-677\"\u003eMK-677 (Ibutamoren) collection\u003c\/a\u003e: all brands held, with strength, pack size and testing set out for each\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/brand-yakka-strength\"\u003eAll Yakka Strength products\u003c\/a\u003e at Free Muscle\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/news\/mk-677-ibutamoren-what-the-research-says\"\u003eMK-677 (ibutamoren): what the research says\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/shipping\"\u003eDelivery\u003c\/a\u003e and \u003ca href=\"\/pages\/guarantee\"\u003ereturns\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNot for human consumption.
