    Heard about Nuvoris through influencers on Insta and the website and prices look legit. I'm not so sure about the recency of the testing data. Any experience with them?

    Has anyone heard of the vendor Grey Axis Research?https://gxresearch.shop/
    There prices are pretty good for single vials. Wondered if anyone has heard of them and are the legit?


    Additionally half of my order was hospira and I checked for the QR and it was present.

    I bought Reta30 from this tiktoker and their website Vylix Research, the reta went cloudy after reconstitution, when I messaged him, he tried to gaslight me saying because it's 30mg it's suppose to be cloudy. These guys on tiktok are all grifting and taking advantage of people of no knowledge or new to this.

    Vylix Research has been shutdown now, and his excuse was that his stepping away because God told him to focus on his clothing brand. But weeks later his got 2 more websites going, Prosper labs and refined biolabs. So basically his doing pop up shops, scam rinse and repeat.


    Awful, eventually, someone is going to get hurt and this slimeball will still be out there peddling his poison under a new alias.

    I try to keep approximately an 8-12 month supply on hand of various peptides. I freeze them until ready to use. My question is about thawing the vial out. Normally I put the vial in a box in a dark cabinet and then reconstitute it. Should I be thawing them out in the fridge?


    @Newenough Thanks for the info! I did a search in this section before I posted but maybe I didn't use the correct search terms. I appreciate your response!

    Not sure if it is my phone but using the search function, it defaults to vendors and turns the screen black. Pressing the back button then get I pop up blocked notifications. Galaxy S24 ultra device. Still able to search but seems like a weird glitch.

    Here is a screen grab of it.

    Hi. I am thinking of buying one of your pens with the 3 ml vial. Is it something special I need to think of if I would like to fill it with the content from three different 1 ml vials?

    I am mixing 1 ml BAC water per vial so I would like to fill the 3 ml pen vial with that total 3 ml content.

    Of course I am going to filter each vial.

    PeptideCritic made a video on how to load em here: https://youtu.be/dHPQQ6YsMEg?is=5qhLL9hBmUEQkBCg It should work for what you’re tryin with 3 separate 1ml vials… don’t skip the breather-needle.

    I'm surprised that Biolongevity Labs isn't listed on here. While they don't sell Reta anymore, I purchase a lot of peptides from them. My GLP3 that I do have from them works fantastically, but alas, that supply is coming to an end. I've also used MOTS-C, GHK-CU, and BPC157 from them.

    Anyway, top-notch service and quality from them...just my $0.02


    @pep_researcher ntxpeptides. Thank me later

    Hi all. I just got my v4 pens in the mail. Super fast shipping as a sidenote! This will be my first time using pens, I am wondering how you all store your pens. Do you put them directly in the fridge or just the cartridges? If putting the whole pen in the fridge, do you put them in a case or just leave it on the fridge tray? Thanks all.


    Nice! Thanks for the ideas. Looking for something more hidden, but I’ll see about these holders

    Has anyone researched and found a possible solution for gum health, specifically receding gums?


    @BeeKind It has to do with inflammation. I had a random 7mm pocket years ago and had to have a minor oral surgery because of it. I think it was Dr. Drew that mentioned on his radio show that his pockets had returned to 1, 2, 3s after doing carnivore and so I tried the same diet and had the same results. I don't think the gums grow back per se, but it definitely reduces those gum pockets which is effectively periodontal disease. I still fluctuate between carnivore and keto, but my pockets are all normal and healthy and I'm 46 now.

    Westend Medical Supply

    So, I did a lot of digging in on this. If your

    looking for Hospira BAC, and you aren't able to get it "OTC" through a wellness center, or a compounding clinic.... No worries. Go to www.westendmedicalsupply.com I bought 8, for 15.80 each, that included priority shipping.. make sure to use the NEWCUST promo for 10% off, and if you want you can get another 10% off by allowing them to text you, which of course you can then reply "stop" to if you want to stop receiving the text. But that will give you an extra 10% off for your next purchase. They have a lot of supplies, and some other peptide related products. They have Single, 3 pack, and 5 pack 30ml vials with an expiration date

    of 1/28, or 2/28.

    Happy Researching, DRTasCanB


    Lol, yup. Im sure some of the maniacs on here are already there. I buy two or three bottles at a time. So all the same batch get the same number.

    They have incredible customer service and so fast in responding. I heard they had a sale and decided to try them out and will be definitely getting my peps from them moving forward. Really great pricing and premier packaging and presentation. Got my package in 2 days.

    Sent an email with my order number and requested to see the CoA since none was published. No response. Trust is earned and is lost in this case. They certainly spend a lot of money on the website and their fancy shipping boxes. Buyer beware.

    I just looked at this site today, it looks like an abandoned place.
  • B

    This is a great site to see pricing as well - one of the great features it has is price history where you can see pricing for specific peptides and specific vendors as far back as they have been affiliated with that site.

    I like to reference this when a supplier claims to have a "HUGE SALE", 99% of the time they raise the prices or raise their crossed out 'list price' to trick you into thinking it's a bigger discount or even a discount at all.

    Would love to have this feature here on peptidecritic!


    @vpeptides, we are looking into it now.

    They claim to work with these three manufactureres. There are three manufacturing partners: Qiangtai Technology Co., Ltd., Shanghai Qiangyao Biotechnology Co., Ltd., and Mokemei Biotechnology Co., Ltd. COA's show MKM which is Mokemei.


    @todd1 I haven’t yet waiting to see what I do for the July 4th sales.
  • S

    I spoke to a medical Rep this morning. Yes, the expiration date is very meaningful. Not just due to the alcohol breaking down. Even mild degradation breaks down the plastic container and increases microplastics and that is the primary concern. There is a low level of microplastics present pre expiration but post the break down happens rapidly. I know people don’t want to hear it but there it is. Injecting micro plastics into your rat is not good expecially at higher levels that occur in long term storage. Hospira has done the testing and that’s why the expiration isn’t 24 months or longer.i


    I actually periodically look at the solutions I make in a microscope x1600. I see that filtered solutions have less of particles that look like plastics. But since I've switched to Hospira water I don't see a lot of debris anyway. When I wasn't filtering and used some suppliers, which I now consider low-grade, I saw some really scary stuff, I even have a picture somewhere. I had no idea what was it.

    Re: Wasteful Pen Cartridge Experience

    Now that my peps are stacking I been using pens. I been filtering all the cartridges as instructed by Randy. Great videos by the way. Lately I have bypassing the breather needle. Using a 13mm Diameter 0.22um filter. When filling the cartridge with another luer lock needle that will connect to the slip outlet of the filter. As soon as you start to feel a slight pressure. Disconnect the luer slip outlet from the filter to depressurize the cartridge. Don't pull it all the way out but enough to blow out with a hiss. The hiss will sound like a gentle whisper saying "baby you got this". It will blow out and dout it *vacuums in. This will not blow out the cartridge plunger. I reconnect it secure enough to hold and still be able to disconnect again. For a 1ml I only had to do it once. Once the cartridge is filled I leave the needle in, remove the filter and reconnect the luer locks to create a vacuum to remove any bad breath or farts molecules that might have been lingering while reconstituting. Then prime the baby for research! If anything gets though then there is nothing LL-37, thymosin, bpc.... can't handle. And seriously, do not lick your fingers like preparing to put together a timeless piece with intricate parts . lol

    Review

    I bought a 10-pack of GLP-2 30mg from NextGen in mid-February 2026, along with a single vial of Reta. Pre-shipment processing took a day longer than I'm used to, but I think they were about to move into a new warehouse and the small delay was no big deal. My products arrived looking really slick and upscale, perhaps the nicest branding and packaging I've seen, but a few days into her first vial my research rat began to feel as if she was steadily reverting to a pre-Tirz state. Symptoms included (among others) frequent hunger pains, loud tummy gurgling, mental "food noise", low blood sugar and weakness between meals. I increased the dosage, in case it was a sudden plateau, but the product never felt like it was working. Simultaneously, my rat reported a wave of skin pains, torso leg and foot aches, tiredness, dizziness, and headaches. Allodynia can be an indicator of diabetes and this subject was pre-diabetic before starting her tirzepatide testing, but her condition had been largely controlled for the previous four months, and the symptoms never manifested this aggressively in the past. By the middle of the second vial, she was bloated and gaining weight, exhausted from lack of sleep, taking large frequent doses of nsaid pain killers, and barely able to get off the couch. Self-funded testing wasn't an option for financial reasons, but as soon as NextGen's product had been replaced by another brand, everything started returning to normal. There was a big stink in March about grey vendor GLP-2 that wasn't Tirz at all, with multiple vials testing positive for endotoxins, and considering the similar timing and the fact that most domestic peptide supply lines can be traced back up the chain to one of the same 5 big Chinese manufacturers, it seems possible this was just a bad batch. I finally reconstituted the single vial of NextGen Reta in June, and that one seemed fine, (in other words it also caused terrible side effects, but they were similar to reactions reported by numerous other Reta researchers)

    @pep_researcher Yeah, I heard about some of their COA problems. I know Finnrick doesn't get much love around here, but one of these days I want to send them one of the NextGen T30 vials, just to see what they say.

    Southern Aminos has been sending out teaser emails for the last few days about their big 4th of July sale....their biggest sales event ever, they claimed. They wouldn't hint at what it was until 8 AM this morning. Their website has not been working all morning. Either they have a crappy server or server ISP, or they greatly underestimated the numbers in the RUO community and the website was hammered too hard. Either way they weren't prepared. Best of luck to them. I hope for their business, they get it resolved soon and back on track.


    @ResearchCat MTT-31 10mg - $41.40 before affiliate discount - it also says limited inventory.

    One star review-

    This was the first vendor I purchased from, naively, from a recommendation from some random person on Facebook - STUPID, I KNOW!

    Anywho - I purchased one vial of GLP-3 which looking now they have the same testing information on their site as when I purchased 2-1/2 months ago so either they use the same generic COA for everything or they sit on a lot of inventory- we know which one is more likely. Extremely overpriced even with their 40% off new customer discount I paid $145 for a single vial of GLP-3 30mg and 1 of their labeled BAC waters. It shipped and was received quickly.

    Test subjects (two different subjects) had horrible side effects at beginning dose, went down to a lower dose (0.5mg) and have not been able to titrate up past .75mg twice a week. Anytime attempted 1mg on a single dose, 48hours later was met with extreme vomiting and gastro issues, bloating and pain.

    After recommendation to try another supplier -found that it might have been the supply.

    Obviously I have done more research and vetted vendors differently since so I will not be buying from them again.
