Ibutamoren（MK677）Basic Introduction

MK-677 is an orally administered growth / hormone secretagogue originally developed by Reverse Pharmacology. A secretagogue is the term for a substance that chemically signals for the pituitary gland to secrete . In other words, MK-677 could be compared to peptides like GHRP-6 or Ipamorelin, only it doesn’t require any injections nor does it have any side effects like GHRP-6. This GHS (Growth / Hormone Secretagogue) was developed in an aim to combat such conditions as muscle wasting, obesity and osteoporosis. It was also targeted towards treatment of elderly hip fracture patients, so there are a myriad of studies done on safety.

Selective androgen receptor modulator
Ostarine is selective androgen receptor modulator(SARM) and a kind of white powder.Ostarine belongs to chemical raw material. It is also known as enobosarm. Ostarine (MK-2866) is a SARM developed by GTx for the prevention and treatment of muscle wasting. It may eventually be a medical prescription for the prevention of cachexia, atrophy and sarcopenia as well as for Hormone or Testosterone Replacement Therapy.
As a research chemical, Ostarine belongs to a class of chemicals know as SARMS or selective androgen receptor modulators. SARMS create selective anabolic activity at certain androgen receptors. In comparison to testosterone and other anabolic steroids, the advantage of SARMS, is they do not have androgenic activity in non-skeletal muscle tissues. Ostarine is effective in maintaining and increasing lean body mass.
Enobosarm (Ostarine, MK-2866, GTx-024) – affects both muscle and bone, intended mainly for osteoporosis but also general treatment for andropause and reversing muscle sarcopenia in the elderly and for cachexia in cancer patients.Nonsteroidal selective androgen receptor modulator (SARM) used in the treatment of osteoporosis and muscle wasting in animal models. A potential compound for the treatment of hypoactive sexual desire disorder.

Ibutamoren（MK677）Ostarine Use

Increasing lean mass gains
Enhancement for strength
Bodybuiling exercise
Joint healing abilities
Hormone Anabolic raw material (even at doses as low as 3 mg)
For bodybuilding
Ostarine is the most anabolic of any SARMS, making its first and foremost use for wanting to gain lean muscle. The gains in total weight will not be comparable to bulking steroids, however the total gains will almost entirely be lean muscle.
For cutting
Ostarine would primarily fit into a cutting protocol for the maintenance of muscle mass while reducing calories. One of the most disheartening outcomes of cutting is the loss hard earned muscle mass. The drop in metabolic rate and hormone levels (T3, IGF, Testosterone etc) with the lack of calories is a perfect catabolic environment for loss of muscle tissue. As Ostarine has anabolic effects, the dieter can cut calories without having to worry about muscle or strength loss. Ostarine has also shown noticeable nutrient partitioning effects among users, another reason why it can be of great help when cutting.
For Recomping
Where Ostarine shines for recomping is in its nutrient partitioning benefits. Calories are taken from fat stores and calorie intake is fed to the muscle tissue. In fact many users report that Ostarine consumed at maintenance calories produces weight loss, while still getting increases in strength and muscle mass
