If it's 17.99 it's probably fake. Especially if it's sten or precision. I hear sten okay again but precision ain't.
I don't understand why one company's product is $17.99 (on sale from $24.99) and another company's is $89.95??? The disparity is too much. Both are respected companies, one promotes USA made, the other does not distinguish...
2 other Co's are $39.99 (on sale from $99) and another is $55, all USA made (so they say)...
Any insight from the peptide experts??

It depends on how much market they want out of it and some do have junk peptides.pepsource i guarantee has 98% pure.Ask for a lab test and it will be proven
