Ipamorelin CJC Receptors and Dosing

Hi all,

I've been taking ipamorelin and cjc w/o DAC for a few months now and had really good results with energy and body comp. I've read that the pulse affect can last for several days so I only take 4 days a week at 1ooiu twice a day.

My first question: do you need to cycle off for the sake of your receptors and can/should you use something like MK677 for awhile before going back on?

Second question: am I correct that 4 days a week is sufficient if using 2x daily?
The stuff is VERY pricey although I recently found a source through a good friend (pro athlete) who lived in China and worked with a Chinese Pharmacy there. He still uses them and the pricing is a fraction of what I pay through my doctor so perhaps price pain won't be an issue in the future.
 
If the effect on receptors is an issue then it is MK-677 that should be avoided. From Wikipedia: "According to some recent research and discussion, there is a concern that its particularly longer half-life might over-stimulate the ghrelin receptors in the brain."

I take ipamorelin nightly. The effects on IGF-1 have been variable, but it has remained consistently good for sleep. I recently tested a night without it, and sure enough I woke early. Back on it the next night and all was well. By this measure, at least, there was no reduced efficacy due to habituation.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
