Thank you for your feedback — we take every review seriously.

We want to address this transparently. ARA-290 is well documented across the research community for gelling when reconstituted with standard bacteriostatic water, which typically sits around pH 5.5. This isn't unique to our product — it's a known characteristic of this peptide. It requires a reconstitution vehicle at or above physiological pH (7.4) to remain in solution. A sterile sodium bicarbonate buffer or pH-adjusted vehicle resolves this.

If other vendors' ARA-290 dissolves without issue in the same acidic BAC water, that likely means they've incorporated buffering excipients into their lyophilized formulation — which is a valid approach, but it doesn't mean an unbuffered product is defective. It means the reconstitution protocol differs.

That said, we should have had this guidance clearly stated on our product page and communicated it better when you reached out. That's a miss on our end and we're correcting it.

We'd genuinely like to make this right. Please contact our support team directly and we'll work out a resolution. We appreciate you giving us the opportunity to address this.

James, thank you for going the extra mile to verify directly with the lab, that's exactly the kind of due diligence we encourage, and it's why we use third-party testing in the first place. Glad the product arrived in great condition and that the value matched the quality. We appreciate the support from Phoenix, and we'll keep earning it.

Really appreciate you taking the time to leave this — means a lot, especially as a new customer. Glad the oxiracetam is hitting the mark for you, and that your co-worker can back up the purity. That's exactly the standard we hold ourselves to.

Sorry USPS gave you trouble on that delivery, but happy we could get it sorted quickly. Fast shipping and responsive support aren't extras for us — they're the baseline. Welcome to Kimera, and thanks again for the kind words.

When we received your email, we issued a full refund for the entire order immediately. We did not receive any further communication from you after that.
We investigated and believe the issue originated from a third-party supplier of our dropper components, which arrive pre-packaged in bulk. We've since addressed this with the supplier and added additional inspection steps for incoming packaging materials.
We stand behind our products and always want the opportunity to resolve any concern directly. Our support team is available at support@kimerachems.co.

Thank you for taking the time to leave feedback. We'd like to address a few points for clarity.

The batch you received was produced less than a month prior to shipment, and every batch we sell is accompanied by a current, third-party Certificate of Analysis confirming identity and purity. At the time of your inquiry, this was our only active batch — there was no alternative batch to offer, nor would there be reason to, given the COA verification.

We understand that individual research outcomes can vary based on a wide range of variables — storage conditions, solvent systems, protocol design, and analytical methodology all play a role. "It didn't work" isn't something we're able to troubleshoot without more specific information, and subjective comparisons to products from other vendors, whose purity and identity may not be verified to the same standard aren't a basis for a refund under our policy.

That said, our support team is always available if you'd like to discuss your research setup in more detail. We stand behind the quality of what we ship, and we're happy to provide COA documentation to anyone who requests it.

Paul, we appreciate the kind words. It's great to hear that HERC, ATPLEX and MOTS-c are performing well in your research, those are three of our standout products for good reason. Transparency and quality are non-negotiables for us, so it means a lot when our customers recognize that. Looking forward to continuing to support your work.
