Hard to say. Get a kit of each, get bloods done and compare the results.
Im about to start running hgh or maybe peptide
Im from canada and i want to know if someone of u know if the black top sold here its total craps or it worth the cost ? And between black top and jintropin theres difference or its the same ... i get the back top and jin from the same source ...
