    So as a fun side i went to chat GPT and asked for some peptide vendors, one of the top ones i saw (and was linked to) was a seemingly new vendor.

    So some flags are waved at me and given the nature of E-commerce and the abundance of scammers i want to try and do as much due diligence to protect myself.

    So from a business-flow standpoint and the fact that peptides can vary wildly in price it stands to reason that there is high-margin in the white-label operation everyone is engaging in. The moats people build for reputable supply chain tends to be branding...so how would a new vendor enter the market. Well any tom dick or harry can create a website take payment (and given the nature of grey-market) accept crypto/zelle only. This is red flag one for me. Its one thing to ship bad product but to black-hole payment with no recourse to potentially get nothing is truly a scam.

    So then i look at, is there a product in existence? Does their COA match the company name from a more neutral third party website? Yes...but...i can't really match the company tested to the company's website, that link is dubious. Lets take my use case. The website is shopapexlabs.net Now, i can go through 99% of the process and see some things. The whois on the website is fairly new and obfuscated, not a bad practice given the nature of grey-market peptides and definitely not a bad idea for anonymity. But if i go to freedom diagnostics to look up the provided assentation number its just going to be APEXxxxxxxx Which would be good if there wasn't 100 different companies named APEX something or other....which leads me to wonder, how do i validate this isn't someone spoofing the APEX name and giving me a link to someone else's COA. not a Fake COA but just lying that that COA is for their company?

    So now i'm stuck in a place...do i risk about $50 to shoot for the moon for something just to see if they ship it? From there do i even trust that if they send me a vial of white stuff i can trust the label and they aren't spoofing that as well?

    Even if i sent it in for lab testing and shelled out another couple hundred on a whim, there's no real way to prove it was white-label product or proverbial snake oil.

    But that brings me back to the real crux of everything. Is the risk that suppliers are taking to bring a product to market and making those Chinese connections really worth the likely 90-95% gross profit margins on products? Are they doing anything other than becoming middlemen? Why, if that's the case, are peptides seemingly still so prohibitively expensive for the layman given its small unit volume cost at scale (this is now a massive market)

    And finally, how on earth is anyone supposed to break these barriers to entry to keep pressure on the supply side to allow for true market stabilization. It seems $10-20k PER peptide in just up front costs on the distributor to take a stab at trusting their original supplier. Is it really just marketing on their end to essentially last leg ship?

    Right now im back to only allowing a credit card to be used, i will no longer attempt to use crypto/zelle but the utter lack of business transparency is really hurting this from a long time thing, and it feels like easy layup for the FDA to clamp down on grey-market stuff because of the inability to hold liable Chinese manufacturers and it seems like the only domestic players in the space are already a part of the bigger player's pipelines.

    Anyway, thank god for this website and its vendor verification program, its not Wal-mart/Walgreeens/CVS Trustworth OTC stuff but its about as good as it can get for now...

    Side note....anyone wanna try and crowdfund to setup a vertically integrated peptide synthetizing plant and do end user distribution state-side? Maybe need 2-4 mil startup....

    So I bought one of those V4 pens from Ava B rose website a while ago after Rory from crush plugger her website on his page. Now I see @randy post on X the ones she sells are fake and inaccurate. Anyone have experience with these and if so how inaccurate are they? Trying to figure out how many units I've actually been taking lol


    @ValGal her filters cost 12 cents on alibaba. I believe they are sterile just like i believe the gym i go to is. If you want v1 pens hers are fine. The v3's she has we stopped selling due to intermittent quality issues 6 months ago.

    @quicksilver80 said: Was thinking what if it had a tab to insert third party tests. That way if someone searches the (company+peptide+date+cap color) it could pop as negative or positive. Also supports the review legitimacy . This would seem problematic. People could attach doctored third party tests.

    Ordered some Vilon but when it arrived and checked the COA it was out of spec to the label. Contacted them about it and got a quick response from owner. He not only sent the missing peptide MG but also sent the other pep I had originally ordered for free by 2 day air.

    Fast shipping great service trustworthy and tested stuff. I will buy from them again!!

    For quality and price with excellent testing and fast shipping these are top of the heap. The SS-31 has been amazing and I’m glad I chose them over Chinese gray market.

    S1 is my first stop when wanting to try a new pep or if I need a high quality source.

    This company communicated at every step of the process and the shipping was fast. I've used the product and it appears to be high quality. Prices are right. Very pleased. I will admit that this is a company I was unfamiliar with before Peptide Critic. For me the other reviews are spot on. Great company and I will be back.

    Ok, this is my journey. I hope this helps people not make the same mistakes.

    Pre Peptide Critic: Newbie who didn't know sh*t

    Pure Labe Peptides - Fake COA's. Fake carbon copy of Hospira. Bad reaction over a week of pain

    Peptide Solutions - Felt nothing from the products Reta included. Fake COA's

    Found Peptide Critic - Everything Changed

    Mile High - Great Products, but has Kovera labs on some
    Glacier - Also Great but all Kovera
    Southern Amino - Great, my go-to for what EZ doesn't carry
    EZ and Nexaph - My absolute go-to. Pricing and product consistency are top-notch
    Crush - High hopes, but their inventory control is a joke, and the constant marketing ploys have turned me off. Products are good, though.

    Grey
    LN and LI Peptide - Great until they ripped everyone off
    GroupBuyKits - waiting for the first order, but Randy says no go and that's enough for me

    Lets all share!!!! and help more people


    @slyger I don't know. I've used both, first Tirzepatide, then Retatrutide for over a year, none of those helped me to lose fat. Now I am trying Tirzepatide + Survodutide. But they help others.

    I’ve been looking at this web site for a few months now, and really like it.
    It seems that the top referenced sellers like EX, Mile High, etc all seem to get good, >99% purity.

    But, some of even the highest rated do not report Endotoxin results. For your own information, <5EU/mg is NOT a numbered result. If you look at a few sellers, they actually report the result like 0.078EU/mg for example.
    Reporting <5EU/mg means it could be 4.9.

    A report listing "< 5 EU/mg" usually means the laboratory set their testing equipment to a highly lenient detection threshold. Rather than looking for absolute trace purity, they are only confirming that the sample is free of massive, systemic bacterial contamination.

    A < 5 EU/mg specification is the absolute baseline bare-minimum for chemical legitimacy. Premium vendors looking to eliminate variables will typically test past this threshold to prove their batches achieve the much stricter limits—like < 0.05 EU/mL or even better an actual number if not <0.05.

    So look at the COA’s presented from your favorite sellers. If the actual Endo isn’t reported, my recommendation is to move on to a cleaner set of samples from a different seller.


    Wouldn't this be more of a lab issue than vendor?

    Hi all,

    I’m new to the peptide community, and my wife and I are looking to start using RETA in the near future. However, the amount of information available can be overwhelming, especially since much of it seems to be conflicting.

    We’re simply trying to educate ourselves and make informed decisions. Could someone point us toward reliable resources or help guide us in the right direction?


    Welcome! Glad you're here.

    Do not order from this Company
    There products are junk and they will short you on orders. 5 Amino-1MQ was Contaminated, the Reta was not Reta and the Tesamorelin was old product.


    Never heard of them and after being in this community for a few months I'm done finding obscure new vendors when theres plenty of vetted options here. And for what, a cheaper price maybe?

    I wanted to share this in the hopes that others might start sharing more testing info here on Peptide Critic....

    I kept seeing people recommending to filter their peps and started doing some research. I found that the .2 micron filters, while good, aren't 100% for bacteria. Granted the bacteria they would miss are very rare and would not be commonly found in lyophilized peptides, but that less than 100% still bothered me.

    Considering there has to be a practical and financial limit to the rabbit hole we go down for research peptide safety, and we all have to find our own comfort level with that, I started doing some more research.

    I found sterile 0.1 micron filters for about $1 each and decided to go one step further and actually test them. We had a batch of Reta from JEEP that failed sterility at Janoshik. (also note that this is when we found out that Janoshik will allow someone to edit a report to change the company name, batch number, etc after the fact for a small fee. Def a red flag for doctoring "verified" tests at Janoshik).

    Test Report #123783 (5).png

    I sent in two of those vials and two of the 0.1 Micron filters that I found. I had them reconstitute the two contaminated vials and test half of each vial unfiltered and half of each vial filtered. This confirmed for me that filtering (at least with the 0.1 micron filters) is viable and effective. Note I mistyped the MG size as 24mg instead of 34mg doh. Hope this is useful for somebody.

    @pep_researcher Yes, I seem to be mixing up sterility and endo... I keep cracking my head on the sides of the rabbit hole as I tumble down.

    Hey everyone, been seeing through my research on Tessa that it can be a potential tumor / cancerous increase due to the GH stimulation. I am relatively new to peptides, just trying to see what others have found with this peptide.

    Regarding the dosage , what would be best recommend, and cycle length ? Thanks guys!


    Dr. Tatem says that HGH does not increase athletic performance. Has anyone who gives it to their research beast found this to be false? https://www.youtube.com/watch?v=Uw6Q5Lje9Qs Sorry to beat this topic with a stick.

    Jeff- kindly relocate if not appropriate for a new category.

    Multi-vial care package delivered today from BioLongevity, pinned both with 30 minutes between each. No site reactions, feel fine, great actually.

    Super intrigued by both, I've done my homework. 60's male in great health, 2.5 year carnivore, focused on maximizing healthspan. Anyone else throwing caution to the wind and researching these two?

    I placed an order because I saw they switched back to Vanguard from ILS and I ended up with a 5 pack from 3 COA's back which are ILS testing. I'm disappointed they ever even went to ILS in the first place. This was my first order with Crush and potentially my last. Why show current COA's if you're not shipping that supply?

    What’s weird is they are always out of inventory and then just did a presale but are shipping from 3 COA’s ago that is really sketchy. Further Rory mentioned he lost orders due to the ILS thing then comes out with a Vanguard COA but ships inventory that was tested by ILS. Even more sketchy. They are good until they aren’t Hate seeing this stuff it has happened to most of us so keep your head up and move on. Peptides are life changing but the market is frustrating as hell sometimes.
