My lab has been using this product for many years and it always works perfectly. We once purchased it from a different manufacturer due to a relative lower price. However, we found that we must increase the dose if the Activin A is not from Peprotech. As such, the cost went up as we had to use higher dose to make it work. Hence, we learnt that Activin A’s purity and quality from Peprotech is superior.
