MK677 and muscle pain

Guys I have a question I can't  seem to get an answer on and that is, How does MK677 cause muscle pain as a side effect (because it does, my joints / muscles have become sensitive) and facilitate growth hormone  secretion for enhanced recovery, better bone density and protein synthesis on the other hand. can someone please explain how and why  does that happen. 

Increase in water retention usually is the cause of pain.

It's due to an electrolyte imbalance.

HGH regulates how the kidneys excrete and reabsorb sodium from the bloodstream.

Taking MK677 increases sodium reabsorption. -> increasing sodium retention puts the balance with potassium/magnesium out of whack.

Potassium and magnesium need to be in balance for optimal brain -> muscles nerve signals.

@Empire, #Muscle addict thanks for the info, at least now i know what the problem is and what i need to do to adress it.
