Been a Modified customer for 9 months. Great product, price and customer service. Their nasals are superior. I’ve tried nasals from other companies and Modified beats them hands down.

Excellent source for research products. Utilized different vendors historically but Modified Aminos exceeded expectations. Plus, our lab tried Modified Aminos on a recommendation and stuck around. Also, reproducibility in my assays depends on consistent sourcing — no complaints. Large research community behind this supplier, and it shows. Overall, this is the research supplier I brag about.

For anyone running experiments regularly, this supplier is worth bookmarking. Batch records line up with what the lab posts before you even order. The research community trusts them, and so does my lab now.

Product arrived with safety seals missing. Product is not viable with missing seals. Asked for replacement and got denied. Other product tested and appears fake. Do not trust this company. Avoid sending your money.
