BBB-Accredited with Strong Ratings

The company has held BBB accreditation since October 2020 with an A rating, and claims to be the only BBB-accredited peptide vendor — a rare credibility marker in the largely unregulated research peptide space.

Responsive Customer Support & Flexible Shipping

Support is available 7 days a week (weekdays 8am-9pm, weekends 10am-6pm), and the company offers FedEx 2-day and overnight shipping with insurance options for lost or damaged packages.

Our top-rated vendor

What customers dislike about Limitless Life Nootropics (Limitless Biotech)

Mixed Customer Review Profile

While Trustpilot ratings are mixed (3.4/5), third-party review aggregators like Sitejabber have shown lower scores, with some customers reporting empty or underfilled vials and disputes over refund practices (store credit instead of cash refunds).

High Free Shipping Threshold

Free shipping requires a minimum $350 order, which is notably higher than many competing peptide vendors and may deter smaller or first-time buyers.

Testing Lab Identity Not Fully Disclosed

Although COAs are provided, the specific identity of all third-party testing laboratories is not publicly disclosed on the website, limiting full independent verification of quality claims.

I received the wrong product

I received the wrong product. I reached out to the company through their websites email and didn't hear back so then I had to call them directly. The person I spoke to sent me a printable shipping label to send back the item, which I promptly did. I got an email from someone in the company (Jacob) asking me to send the product back without taking any accountability for sending me the wrong product to begin with. It was odd to me that I had to respond by asking “when are you going to send me what I paid for?” Since he didn't mention it. He told me “it would ship out the next day and he would send me tracking info when it did.” Welp, 4 days later I never received the tracking info and I had to ask again, “when are you going to send my product?” What was worse was I received a survey from Limitless asking how they handled the situation. I gave a poor review and explained why and no one reached out to try and make things right or apologize for the inconvenience. Why send out a survey to begin with if you're not going to do anything about it? pathetic customer service. I finally ended up getting what I bought after all the hassle and terrible customer service. My order # was 189956 and I still have all my correspondence with “Jacob” to back every word I said.

An edit to my first review. I was able to contact Limitless by phone and they informed me the shipping was my error. I do apologize, for this error and for my former review. The gentlemen I spoke with corrected everything and I received my product quickly. Trying the anti aging serum now, we'll see. Any help with my 11's would be great.

Terrible Customer Service, not worth dealing with

Update: after writing this review, I finally got a response that generated my refund a few days later. Not sure how the products are working for me, but the customer service is terrible. I signed up for their ACH payment to receive a 5% discount, and it was not given to me. Their system was also flawed in that they deducted the money from my bank immediately and then failed to ship my products because their system status said awaiting payment. Finally got it shipped, but it's been 2 months since my order date and I still have not received the overcharge refund. I've made many calls and emails and the promise to return my call goes unfulfilled.

Extensive selection, human customer service, excellent packaging

They have an extensive selection on their site, a lot of nasal spray options that are hard to find. I would rate their pricing as very reasonable. This is the first "peptide" company I've delt with where you can actually call and talk with a human (in mins) if you have an issue. I ordered 3 nasal sprays. Anyone who complains about having to mix didn't read the description. Also, reconstituting before use, ensures minimal degradation. Their packaging was the best I've ever seen (I've ordered from ~ 6 other vendors). I'll definitely order from them again.

Never ordering from them again

Limitless has become a company that completely disregards product quality. They take large quantities of bulk powder and divide it into smaller vials in-house, so they don't even know the actual net peptide content of each product, yet they charge prices as if you ordered directly from Pfizer. Update after their reply: a clean room doesn't make non-sterile bulk powder sterile, weighing gives gross weight not net peptide content, and calling manufacturer-vialed product 'premium' while selling hand-divided powder at regular prices is misleading. It's simply no longer worth ordering from.

Bitcoin scammers.

They took my money (BTC) never shipped a package, became non-responsive on their customer service outlets. In other words, direct theft under the pretense of selling a product.

Semax and Selank amazing for executive function

I've purchased Semax and Selank which have been amazing for executive function, drive, and mental focus. The PE-22-28 peptide eased my depression so much I was stunned.

One of the highest quality suppliers in the peptide space

Limitless Biotech is by FAR one of the highest quality, most reputable suppliers in the peptide space. I have used their semaglutide, semax/selank, and GHK-Cu — all potent and effective. Cannot recommend them highly enough.

Batch-to-batch inconsistency with BPC-157

Ordered from them 2 times. Once was fine, the second, not so much.

Received empty bottle instead of 30mg SEMAX — contained only 0.01mg of product. Multiple emails went unanswered for over a month. First order was fine but second experience left me with no product and no response from support.
