Due to supply chain issues during COVID-19, we were forced to turn to alternative pump suppliers to fulfill our orders. Unfortunately, those pumps were unreliable and not the same quality of our standard pump. We have corrected the issue and all new products are being finished with a stronger, more reliable pump. We still have the substandard pumps on some of our inventoried products. If you receive a product with a poor functioning or broken pump, please email info@pharmacopia.net and we will send out a replacement pump to you right away.
