Is there anything to worry about?
Yes there is. In fact, if you abuse the use of fat burners then there is certainly a lot to be worried about. You would be preparing yourself for side-effects which could be short-term, long-term, reversible or irreversible. Sounds horrifying? It is intended to be so because unless you use these things under proper guidance of an expert or medical practitioner, you are making a good case of what not to do. There have been cases in the past when people go to extremes in their desperation and suffer from side-effects. It is generally not the product that has to be blamed but the greed of the user for overnight success.
But for a use as an athletic abilities enhancement supplement we have to consider 2 things. The mechanism of human growth hormone and IGF-1 was observed with injections and doses of actual hormones. Many studies have been performed on subject that are being considered not-healthy (such as people with growth hormone deficiency syndrome, or obese, HIV patients, etc.), those studies have found the positive effects of growth hormone supplementation on lean body mass preservation, lipolysis activation, protein breakdown decrease, positive nitrogen balance, among the others.
My first question has to be “has your lab animal had problems with hypoglycemia before?”
Secondly, studies have shown that the nature of MK2866 lowers the blood glucose level by 11% while simultaneously reducing insulin residence by 27%. Typically this shouldn’t develop into a problem, but for lab animals with prior hypoglycemic issues, this could lead to feeling light headed and fatigued. I would recommend using GW501516 and SR9009 until the condition is under control. You CAN use MK2866 in conjunction with blood sugar stabilizing medications.
