Never ordering from them again
Limitless has become a company that completely disregards product quality. It turns out they take large quantities of powder and transfer it into smaller vials, which is something that shouldn't be done. This process is only supposed to be done when it's in liquid form. they don't even know the actual net content of the peptide in each product. Not only are they selling low-quality compounds without knowing the net weight, but they are also charging prices as if you ordered the substance directly from Pfizer. It's a company that is simply no longer worth ordering from. Update: Your reply confirms the point of my review — raw/pure products arrive as bulk powder and are divided into vials in-house. Three things it does not address: 1. Dry lyophilized powder is not sterile when it arrives in bulk, and it cannot be sterilized after it is divided. A clean room and PPE reduce contamination; they do not make a non-sterile powder sterile. The only process that does is dissolve → 0.22 µm sterile filtration → aseptic fill → lyophilize in the vial. That is what every manufacturer-vialed product goes through — including the ones you call "premium." 2. Weighing powder on a scale gives gross weight, not net peptide content. Net content requires an assay against a reference standard, plus moisture and counterion content. Do you publish sterility, endotoxin and net-content results for the vials you fill in-house — or only the bulk COA from your supplier? 3. Manufacturer-vialed lyophilized product is the industry standard, not a premium tier. Labeling the standard as "premium" while selling hand-divided powder as the regular product, at regular prices, is misleading to any buyer who doesn't know the difference — and most don't. That is exactly the concern I raised.

Thank you for sharing your feedback. We’d like to clarify that our raw/pure products are received in bulk and carefully weighed and transferred into individual vials in our in-house lab using high-precision, pharmacy-grade scales. Our lab is maintained as a sterile environment, with proper PPE and strict handling and sanitation procedures used to maintain clean-room conditions. Our premium lyophilized products arrive already prepared in individual vials and do not require this same process. Regarding pricing, we invest significantly in independent testing and quality control to maintain the purity, quality, and consistency standards we expect from our products. While we understand customers have many options, we believe it’s important that our processes are represented accurately.
