i am still one of the persons that believes there is a difference between good generics and pharma.
And ive tried them almost all. Only tested brands and only brands with high purity according to janoshik tests (i dont believe in those chinese hplc)
Dont get me wrong, the tested good generics (optis, mauvetops, QSC) are good and they def work, but they do not compare to autenthic jintropin or authentic humatrope imo.
In the off-season the difference is not big - however, autenthic jins or humatrope lean me out far faster than the generic brands.
I am not sure why (purity is slighty better on those but this cant be the only difference).. maybe with the 3d structure of the amino chain sequence or something like this
