It works in a different way bro. It stimulates your body to produce more gh rather than simply being exogenous growth.
this means that individual response will vary (unlike injecting gh where 4iu is 4iu).
people have had bloods that suggest an intense of 2-4 iu a day can be achieved but others less so. If you combine it with cjc then you will increase the results considerably (can get up to 4-6iu equiv)
so the answer is that you can’t directly compare them but personally I’ve been very happy with the mk cjc combo and notice benefits from mk alone
