    I can confirm the fat loss and muscle building results after using this product. Buying again and trying the GW501516.

  4. christo9999 (verified owner)

    I have multiple tendonitis in my arms which are difficult to heal and this is my magic healing potion.

    A couple of minutes after i take a normal dose 25mg, my tendons pain reduce dramastically its like magic.

  5. immutable (verified owner)

    Amazing results for someone new to sarms, most noticeable was fat loss benefits, muscle strength and anti catabolic with muscle wasting. Took 25mg daily , no sides whatsoever, blood sugar within normal range, prolactin no issues, hunger is mangeable, lethargy subsides after 3weeks. Worth trying even if standalone.

Mk677 in Canada or Ibutamoren is an orally administrated 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 growth hormone. In other words, Ibutamoren 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.

Growth hormone pulse intensity can be increased through 4 possible mechanisms:

  1. Increasing GHRH (growth hormone releasing hormone) release.
  2. Amplifying GHRH signaling in somatotrophs of the anterior pituitary gland.
  3. Reducing somatostatin release (somatostatin turns off GH release).
  4. Inhibiting of somatostatin receptor signaling.

MK677 was found to work through all four of these mechanisms. After ingestion, Growth Hormone (GH) was shown to increase dose dependently, at doses starting at 5 milligrams (mgs) a day.
In a study on it’s effects on catabolic states, a once daily oral dose of 25mgs was given to healthy young men subjected to short-term diet-induced nitrogen wasting. After 7 days of this dose, the subjects showed a sustained increase in serum concentration of IGF-1 and Growth Hormone; in addition, the nitrogen wasting was reversed, showing great potential for treatment of conditions involving muscle wasting.


Trials testing the effects of this GHS on fighting obesity showed an increase in lean body mass, but neither total, nor visceral adipose tissue was effected. This study gave subjects 25mgs of Ibutamoren per day for 8 weeks. The subjects showed an increase in basal metabolic rate after 2 weeks, and an increase in serum levels of GH, IGF-1 and IGF-1 binding protein-3. Increase in lean body mass was hypothesized to be caused by an increase in calorie deposition into the muscle and appetite decrease as opposed to reducing fat storage directly.

A study done for the treatment of osteoporosis and bone mineral density showed some increase in bone density, so there is a true impact on bone mineral density. This can help with injury recovery during your cycle.

Other possible benefits of Ibutamoren are associated with improved sleep, improved complexion, increase in energy levels, increase nitrogen retention, increase strength and an improved sense of well being. In addition, some studies also suggest that an increased immune system response was caused by MK677, meaning it boosts the immune system to a degree.

Elevated growth hormone has literally endless list of benefits to the human body, why do you think everyone tries to get their hands on HGH? That’s why Ibutamoren (Mk677) is so effective, it increases Growth Hormone and IGF-1 levels.

IGF1 vs MK677

As the studies show, Ibutamoren can be used for a number of reasons from growing muscle mass, to getting shredded. It does not compete with the levels of growth hormone one can get from exogenously administered HGH, so you can use it with hgh cycles. In fact, by using Ibutamoren, you can easily get amazing increases of your own natural growth hormone pulses without having to deal with annoying and painful daily HGH injections. It’s like using HGH without having to inject daily.
In a multitude of studies, Ibutamoren (Mk677) increased IGF-1 levels by between 39-89%. To give you an idea of what IGF-1 does, here are some IGF-1 benefits:

▸ Increased Fat Oxidation (fat loss).

▸ Increased Muscle gains (lean mass).

▸ Tightening up loose skin.

▸ Healing old injuries.

▸ Healing Bones, Tendons and Ligaments.

In fact, many users report growing up to 6 lbs of lean muscle mass in 8 weeks of IGF-1 only cycles. That’s an amazing result, but injecting IGF-1 daily is painful, costly and frustrating. Now, there is an oral-only alternative. You can buy MK677 in Canada by adding it directly to your cart.
