The packaging really stands out compared to most places. It arrived completely clean, sealed, and clearly put together with a lot of care. Excellent quality control.

Extremely fast delivery. Ordered from Texas and the package arrived in just two days. Everything was neatly secured and properly handled from start to finish.

This is my second time ordering from NextGenPeps, and they haven't let me down. Their BPC-157 arrived well-packaged and exactly as described. I really appreciate a company that takes shipping speed and product integrity seriously. Exceptional service all around

I placed an order for $190.61 & then realized I ordered the wrong items. I reached out to support who helped me almost immediately- he cancelled the order and issued a refund & let me know it could take 5-14 business days. That was on 8/19/26. I waited until 9/8/26 to let them know the refund still had not posted to my account & they were very reassuring & let me know it could take 21 business days for some bank statements to show the refund posted. Well, it is now 9/19/26- a month since my original order & still no refund. I feel like an idiot because I seem desperate to keep asking about the refund. Aside from my issue, the customer service team is very responsive, respectful, & very good at putting you at ease. I will keep waiting, but recommend anyone to be very careful when placing order so you don’t need to make any changes & do not cancel/ do anything that requires a refund.
