Customer reviews

Moderated, published as written, and never averaged into a rating we cannot show.

Reviews on this page are moderated before they appear and then published as written. We do not edit them for tone, we do not filter by rating, and we do not show an average until there are enough real reviews for an average to mean anything.

Reviews from our Google listing

Early reviews from customers who bought directly from us when we launched, shown word for word. This section is a selection, not every review. See all our Google reviews, including critical ones.

Mark was very helpful and explained the LabFirst waitlist clearly. I liked how straightforward the process was and how I received updates without having to keep checking for information myself. The available items were sent out first, and I was notified when the remaining item was ready. Everything was handled smoothly, and I'm happy with the experience.

Sarah made the LabFirst waitlist process easy for me to understand. I appreciated how clearly everything was explained and how I was kept informed without needing to follow up constantly. The items that were available were shipped first, and I received an update when the backordered item became available. Overall, the process was smooth and convenient.

I recently ordered from LabFirst and had a really positive experience! The website was easy to navigate. Finding what I needed and completing checkout was quick and straightforward. Shipping was impressively fast; my order was processed and arrived sooner than expected. Pricing was already competitive, but applying their coupon code made it even better! Overall, a smooth and simple experience. I'd order from them again!

Nice website and fast delivery. The compounds were packaged well for shipping. Will buy from again.

Dave patiently talked through the product name, listed amount, and form while I was choosing my LabFirst order. A purity report came after purchase, with a result of 99%+. The help with understanding its labels put me at ease. I could ask about the paperwork without feeling awkward, which made the service stand out beyond the ordering step.

Dave made my first LabFirst Peptides order easy to sort out. The listing showed the size and cost clearly, and I got a friendly explanation when I needed one. There was time to look over my choices before paying. That simple, helpful approach made buying from a new supplier feel much more comfortable.

Reviews left on this site

None released yet. Leave one if you have ordered from us; it is published as written once a person has read it.

How this works

A review can only be left by someone who has ordered, it goes to a human queue, and a person releases it. Released reviews appear here and on the product page for the compound they name. Nothing on this site carries star markup that is not arithmetic on reviews a person released — which is why most product pages currently show no rating at all.

What a useful review covers

The reviews other labs find most useful are specific about the order itself. How long it took from order to doorstep, and whether the tracking matched. How the vials arrived: sealed, labeled, nothing cracked. Whether the lot number printed on the vial matches a certificate on the Verify a COA page. And if you contacted us, how quickly we answered and whether the answer actually helped.

What we cannot publish is anything about using a compound in people or animals. Everything we sell is for laboratory research only, so a review that describes personal use is declined, whatever its rating. A short review that sticks to shipping, packaging and paperwork is more useful to the next buyer than a long one that does not.

If something went wrong with an order, contact us first. A review is a slower way to get a problem fixed and we would rather fix it.

Certificates for every lot are at Verify a COA, and the research library covers handling and storage.

FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. NOT FOR PERSONAL, MEDICAL, DIAGNOSTIC, THERAPEUTIC, OR RECREATIONAL USE.

A short note when new certificates post, when a stability result surprises us, and when a guide worth reading goes up. No promotions.
