Buddy, I'm not a rep, but people used to speak of 250mcg/w.
Real hMP is the strongest systematic Myostatin Inhibitor, but it may not be the most selective, resulting in some other organ growth.
Follistain 288 is the strongest version of Follistatin with the highest affinity for Myostatin. Follistatin 344 has less of an affinity for Myostatin. yet it is more-selective towards striated skeletal muscle. This is the sort of thing that I'm talking about here.
A lot of people may not concern themselves with such things, willing to sacrifice organ growth for muscle growth, similarly to GH, but it is something to consider.
So now your question becomes "does Superior offer legitimate hMP?" This is a complex question, and some of the reps aren't willing to address it because there is a lot of BS regarding this. Superior may offer many good peptides, yet most Myostatin Inhibitors out there are currently sub-par, regardless of company.
