MK677 is a new drug in the bodybuilding world. Its benefits have not been officially confirmed yet, but most people who take it, swear by it. Even though it’s mainly associated with bodybuilders, people with disabilities and hormone deficiencies benefit from it as well.

Many people often mistake Ibutamoren for a SARM, which it is not. It is not a typical growth stimulator either.

Ibutamoren (MK677) is a potent, long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, mimicking the growth hormone-stimulating action of the endogenous hormone ghrelin.
Growth hormone is needed for the body to perform optimally. It plays a crucial role in the development of muscles and tissue.

It’s a quite complicated process but what you should know is that Ibutamoren does not interfere with other biological processes such as natural hormone production. This means that you will experience a boost in growth hormone levels without side effects.

How does Ibutamoren MK677 work?

    This product has been great! I have always had a hard time gaining and keeping weight. I decided to try the MK-677 because of all the positive feedback I’ve seen here and on other sites. Within the first 2 weeks I was able to gain 5 pounds and finally got me over the 200 lbs mark. Something I had only done one other time 2 decades ago. I definitely feel stronger. Doing more reps for more sets and you just feel the difference. And that’s just the product.

    Now, my review of Prime Sports Nutrition is another big A+! The level of commitment these guys (and gals) have for making the customer happy (actually met a fairly personalized video of appreciation) and the speed with which they ship the products is second to none. I’ll be sticking with PSN for my specific supplement needs. You guys are the best!
