The powder wasn’t kept cold or shipped in any temperature controlled packaging. For peptides this is a major issue.
Response from Purgo LabsOct 3, 2026
Hi — thank you for writing this. I looked up the order. Those vials are sealed lyophilized (freeze-dried) research powder, not mixed liquid. This is exactly how they should be shipped - let us explain and provide all the proof: We buy them from a U.S. 503A compounding pharmacy that makes them to FDA 503A standards and ships them to us in this same format: dry powder, no temperature-controlled packaging. After we receive them, we send samples out again — also without a cold chain — to an independent U.S. lab for purity, identity, endotoxins, and heavy metals. We have 100+ public COAs from that process. Those lots have already made two ambient mail trips, including out of Phoenix, and the reports do not show a degradation problem from that shipping: https://www.purgolabs.com/lab-reports If shipping peptides in room temp packaging is incorrect, why do all us pharmacies and peptide producers ship the same exact way? Dry peptide powder is the long-lived form. It is specifically designed to withstand heat and room temperatures. This is how the pharmacy that produces and makes the peptides themselves ship them to us - a quick google search or chatGPT will tell you the same -lypholized powder peptides do not need to be shipped in cold temp packaging. Here are three separate published articles proving this: FDA labeling for lyophilized tesamorelin (Egrifta SV) stores the unopened powder at room temperature, 20–25°C: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=3d783378-b02d-4f19-99dd-0fc91a042224 USP (2023): lyophilized gonadorelin lost <1% after 34 months at 45°C — over two years, above room temperature, like shipping conditions: https://pmc.ncbi.nlm.nih.gov/articles/PMC10338602/ A lyophilized four-peptide vaccine formulation was estimated stable 18+ months at 25°C / ambient: https://www.biorxiv.org/content/10.1101/2025.08.14.670419v1 If this answers the shipping concern, please consider updating the review. We would be happy to put you in contact with the owners of the pharmacy producing these peptides to share the same info about how they can and should be shipped. If something is wrong with the vials themselves, email [email protected] and we will take care of it.

Good stuff, good delivery time, good communication. Will be buying again

Max was very helpful and quick to resolve my problem. I've used Purgo for several months with no problems at all. I had some user error issues and Max was polite and extremely attentive to the situation.

I have been using Purgo Labs for a handful of orders over this past year. Their products are solid, their prices are great, but it’s their backend operation that keeps me coming back. Every single order I’ve had has been turned around lightning fast and their response to questions or concerns has been equally prompt. Not too long ago I had an issue - that ended up being something is the shipping co messed up - and Purgo’s customer service looked into it and got back to me SAME DAY. I know you can’t always expect that type of turn around, especially as companies grow, but it’s them making what is important to me also important to them that really makes them stand out. It’s why I keep coming back and it’s why I recommend them to others. You just don’t get that too many places these days. Give them a shot. You won’t regret it. Also, side note, they have a Honey Balm GHK-CU (2400 mg) - not normally into those sorts of products but it was part of a promo and it is fantastic. Definitely will be adding it to my normal orders.

Delivered early. Only complaint is I am not sure about reconstruction but I will figure it out

Being most of us reading these reviews are looking to inject unregulated supplements into our bodies, I have spent a month researching Peptide suppliers as I previously trusted Peptide Sciences. I was hoping to have formed a different conclusion on Purgo Labs since they are local and had some positive feedback. I'll change the review anytime the evidence shows otherwise. First, I noticed that 90%+ of people that left positive reviews, it's the only Trustpilot review they have ever made. Made me suspicious. Then the address on Via Linda St in Scottsdale is a shipping store that Purgo has a PO Box in. Then they have 3 FB pages I found and one under LLC that has been flagged. None have a following. Finally, what brought me to realize I was probably not looking at a legitimate supplier, was their COA from SteriGenix. I thought, wow that's a big named company. Not like a few seemingly common others "Peptide Focused" lab's that sure seem suspect and common among sellers that have very recently exploded into the market. Then I realized, it wasn't Sterigenics, who's name is trademarked and a subsidiary of Sotera Health. It was Sterigenix Analytical LLC with a .com, that says it's a lab in Jacksonville Fl, not accepting new clients as it's transitioning ownership. A COA from a facility without a lab, license, address, phone number or even an LLC registered anywhere in the state of Florida is not remotely certifiable evidence the product's Purgo's selling are pure and free of contamination. Another COA they show is from Ethos, who is also local. Clearbatch .net under Ethos lab review, shows they don't have a lab anywhere on site, are also new and a "Supplement Focused" testing facility. Conclusion, it's the same ring of sketchy peptide slinger's with way too many red flag coincidences from a company selling a potentially deadly product meant to inject into your body. Bummer.

Hi JT, you said you would reconsider your review if the evidence showed otherwise. We welcome that opportunity and are willing to make the verification process public. Choose any current batch and a laboratory you trust. We will ship a vial to that laboratory—or ship it to you so you can submit it yourself—with shipping and testing costs covered by us. We are happy to publicly document the batch, shipment, and resulting report, with your permission for anything involving your personal information. Your review leaves out the majority of our published testing. More than 70% of our COAs come from other labs, with 60%+ being from Freedom Diagnostics in Franklin, Tennessee, which provides HPLC purity testing, LC-MS identity confirmation, and a public report-verification system as the others do. Our recent testing also includes six-plus COAs from Kovera Labs and five-plus from ILS Laboratories. Our testing history spans Freedom, Kovera, ILS, Ethos Analytics, and Sterigenix. That is five different laboratories all giving their own independent results for our products across the span of our inventory. We previously used Sterigenix alongside Freedom, but no longer use that provider. That change does not, by itself, mean its previous results were false. If those reports do not satisfy you, our offer to independently test a current batch at your chosen laboratory stands. This is why the COA's are public for you to view - the lab used is not hidden in any way, and is in-fact highlighted for all customers to see and choose themselves. Ethos Analytics is a Phoenix-based analytical testing provider, with a published address of 3020 E Camelback Rd, Suite 397, Phoenix, AZ 85016. You can contact Ethos directly to discuss its laboratory services. This company accepts in person drop-offs of samples. We are not sure what the trust issue is here, but again, we will test our products wherever you choose. Many customers have also independently submitted our products for testing. Among the results shared with us, none have identified an issue. We welcome independent testing because it gives customers evidence beyond reports supplied by the seller. The Scottsdale address is our public mailing address. We keep our operating warehouse address private for the security of our staff and inventory; a mailing address is not evidence that a business is illegitimate. If you are aware of other peptide companies, Facebook bans all accounts that mention the word peptide. Check any other long standing company, you will find that they have had many accounts banned. Our instagram account last about a week as before being deleted on the platform. This is standard across the space, we challenge you to research this. Likewise, a business having good Trustpilot reviews does not make the reviews fabricated. We have served more than 12,000 customers over the past year and invited them to share honest feedback over the past months. We have built our trust profile with legitimate verified reviews, which trustpilot monitors themselves, and verifies using randomized invited emails for the reviews. Many are first-time reviewers. Their experiences deserve to be considered on their merits. We have not been able to identify an order or previous support inquiry associated with your review. Purchasing is not a requirement for asking questions, but we encourage you to contact us before presenting assumptions about our business as established facts. We are happy to clarify these matters for anyone. Our reports are available at purgolabs.com/lab-reports. Please contact [email protected] with the batch and laboratory you would like to use, and we can arrange the next steps.

Had an issue with my peptide not dissolving completely. Emailed customer support and they responded within 5 minutes! They sent out a replacement vial promptly the next morning and it's perfect. Now that's what you call "customer service"! Very satisfied with Purgo Labs.
