I'm sorry, but LOL. Over $100? You clearly have no idea how much the raw materials for MK-677 cost. My guess is that you have believed the horseshit that certain unscrupulous peptide companies are posting online. You know, the one's charging $100+ for their MK-677 and then claiming that anyone who sells MK for less is using low quality material. They are pushing down their prospective customers' throats.
The bottom line is that MK-677 costs about 16K per kg even when buying from the best sources. Do the math. Anyone selling MK-677 for over $100 is making a killer profit, especially if they are a research-peptide company, as they don't have to pay a GMP manufacturer to encapsulate the stuff for them. They just put it in bottles themselves.
