Best paperwork I have seen
Full analytical package including the raw chromatogram files. Most suppliers send a one page summary and hope you do not ask.

Rexha Research is a mid-table supplier with a solid analytical record and a straightforward buying experience. Pricing sits near the median of the offers we track, which is generally a healthier position than the extreme low end, where analytical spend is usually the first thing cut.
The reviews we have moderated point to accurate stock listings and predictable dispatch, with the occasional slower delivery during restocks. Nothing in the pattern suggests a systemic problem, and the score reflects a supplier doing the basics properly without yet matching the documentation depth of the leaders.

The lot report went live on their site before the parcel even left. I could check the figures while the order was in transit.

Courier delay rather than anything the supplier did. Support proactively messaged with an updated tracking link, which was appreciated.

The outer box arrived visibly dented and every vial inside was still perfect. Whoever packs these knows what they are doing.

Product pages state what has been tested and what has not. I trust a supplier that admits the limits of its own data.

Queried a discrepancy in the storage note and had a corrected label emailed the same afternoon, along with an explanation.

Insulated liner and gel packs that were still frozen after two days in transit. Clearly they think about how the product travels.

Ordered two research vials and the certificate of analysis lined up with the batch number on the label. Chromatograms were readable and dated, which is more than most suppliers manage.

Quantity, presentation and purity all matched the product page. No surprises, which is the highest compliment in this space.

The wrong report was in the box initially. One email and the correct one arrived within the hour with an apology.

No issues with the material or the paperwork. The outer box was a little light on padding, though everything arrived intact and sealed.

Slightly more than my last order a few months ago. Still reasonable given the level of testing they publish.

Comparing reports across three separate lots and the numbers barely move. Consistency like that is rare at this price point.

Second order placed a month later and the experience was identical. Same packaging standard, same paperwork, same dispatch speed.

Order confirmation, dispatch note and delivery update all arrived without me needing to ask. Simple things done properly.

Solid service and good material. A wider catalogue and a tracked shipping option as standard would make it a five.

Clean intact cake in every vial, no cracking or residue on the stopper. Reconstituted clear with no cloudiness.

Asked for the full analytical report for an older batch and had it emailed within a few hours. No pushback, no vague replies. That transparency is the reason I keep ordering.

Mass spec and HPLC results supplied for the exact lot, both dated within the last few months. That is what I look for first.

Shipped the next working day with cold packs still cold on arrival. Vials were intact and the seals were untouched. Communication was clear the whole way through.

Every vial had an intact flip cap and the shipment carton was sealed with numbered tape. Easy to verify nothing had been opened.

Checkout was simple, confirmation arrived instantly and the dispatch note included the batch numbers. No chasing required at any point.

Everything arrived as described and the seals were intact. Only small gripe is that the invoice took a couple of days to come through.

Every vial carried a batch code that resolves to a report on their site. That alone puts them ahead of most of the market.

Third order in six months and the reported purity has been consistent each time. Labelling is clear and reconstitution notes are included in the box.

No frills to the presentation but the important parts are right: sealed vials, matching paperwork and quick dispatch.

The material and service were both good. I would like to see purity reports linked directly from the product page rather than a separate archive.
