I will start by saying that I haven't yet found a testing group for this recent batch of Tirzepatide 30mg, so I'm only reviewing the ordering experience for now. QSC's history as a company is not without red flags; their reputation took a particularly big hit when they shut down suddenly in late 2024/early 2025, and then resumed operations some months later, without ever compensating the many former customers whose missing orders they had pledged to replace or refund. In addition, dozens of would-be buyers have been scammed by imposters using QSC's name and images, which has lead to further ill-will toward the actual brand. I took a calculated risk when I decided to purchase tirzepatide from QSC, and did a lot of due diligence first, being very careful not to click on any lookalike links or addresses. To order, I downloaded the most recent version of their price sheet pdf, wrote up what I wanted to buy, and how I wanted to pay for it, then sent a private message to the rep "Tracy" (probably not his/her real name), who responded with a total amount due, and a choice of crypto payment addresses. During my stablecoin transfer a transaction id or "hash" was created, and I sent a copy of this hash in a second private message, as proof the invoice had been paid. After that I just waited quietly. There's no confirmation, no hand-holding and no customer service to speak of with QSC; I could see two green check-marks appear near the message time stamps, indicating "received and read " and about three days later I was given an order tracking number. My 2 kits had a surcharge of $20 for domestic shipping by USPS Ground Advantage, which was probably about $17 more than it actually cost. The packaging was an envelope not a box, and transit time from Los Angeles was about a week. Shipments can be tracked by using Informed Delivery, so I knew the moment mine arrived, which happened yesterday at 6PM. The kits are sent bare, with no paperwork, no QR, no batch code, and nothing written on the actual vials or their plastic caddy. There is a printed sticker with a sku on the outside of the packaging, which supposedly identifies the product, so I saved my shipping materials for future reference. QSC imbeds a Janoshik testing link in each product's name on their Telegram price sheets, but I was sent a T30 batch with dark gray caps, while the COA shows an orange-capped sample, and it's also from November, 2025, so I highly doubt it's applicable to this mid-June 2026 order. I reconned a sample, but finding a co-testing group has been difficult, so all I can report for now is that my cost including shipping was $260, the order arrived intact, and the totally-unlabeled peptide vials passed visual inspection. Hopefully they actually contain 30mg of GLP-2, and won't kill me!

I bought tirzepatide from Certified twice, when I was first venturing away from tele-health and prescription peps and didn't really know where to look for vendors. I realize now that their prices are quite high, and even if he isn't a sex pest, Jason does appear to be kind of a dick, based on screencaps I've seen of his communications with other buyers, but that being said, my vials were totally fine, and the peptides performed perfectly both times

Niimbot label makers. Their whole product line seems to be on sale, but not all of them are listed in the link below, which is to their storefront. If you search for Niimbot in the main Amazon search field it will pull more results, some of which are around 40% off. I do not own one of these devices myself, but in the "Calc and Tools" tab at the top of the PC page, there's a drop-down which includes a label-generating template, and it should work with any Niimbot models that support 20mm x 40mm blanks: https://www.amazon.com/stores/NIIMBOT/page/5C84C486-CEE1-4AE4-BED1-2A68BBBD2CC4

@Atlas I've split my tirzepatide dose ever since I started back in September, and it has been working, with no terrible side effects, so I just kept going that way. I'm a 5'6" woman battling metabolic syndrome, early-stage diabetes, and a huge menopausal visceral fat gain, not to mention inactivity due to a leg injury, so it's been very slow going, but the tirz is still helping, although maybe not as noticeably as at the beginning. I'm at about 3.5mg per shot now, and like you I got the Reta FOMO recently, so I decided to try adding a small dose of that once or twice a week, but so far I am NOT a fan of Reta at all, and will probably give up on it entirely as soon as this bottle is gone.

I bought a 10-pack of Tirzepatide 30mg from NextGen in mid February. The packaging is really slick and nice-looking, but a few days into the first vial of NextGen's T30 I began to feel like it wasn't working very well. I upped my dosage, in case it was a plateau or an underfill, but didn't see improvement. At the same time I was also experiencing skin pains, torso, leg and foot aches, tiredness, dizziness, and various other random and intermittent ailments. Some of these can be diabetes symptoms, which would also suggest the pep wasn't having its usual effects, but by the middle of the second vial, I was sufficiently concerned that I decided to discontinue, and find another supplier. Their batch documentation and coa transparency isn't the greatest, so I've been meaning to send a vial in to Finnrick just to see what they say (can't afford $200+ for solo, self-funded testing). There was a big stink in March about grey vendor GLP-2 that turned out not to be Tirz at all, as well as vials with really high endotoxin levels, so with all these resellers sourcing ingredients and finished product from just a handful of Chinese manufacturers, it's not inconceivable that I got a bad batch. When I finally did recon my one vial of NextGen reta, it was fine. Did anyone else experience poor performance, or unusually severe allodynia with NG's late-winter/early spring T30?

Also, very good deal right now on these alcohol prep pads, (200 wipes for only $2.34, a major discount, although they're nearly out of stock): https://www.amazon.com/dp/B0D7QMNRR8?psc=1&smid=ATVPDKIKX0DER

@mrjoshua44 I'm so sorry; that must be incredibly disappointing! If anyone reading this has been curious about the various "elin" peptides, their risk factors and research protocols, I highly recommend this detailed comparison and explanation: It's really long and technical, but fascinating food for thought, especially when it comes to assessing potential downsides vs benefits. https://www.youtube.com/watch?v=MVG006bW_3s

@Eleanor That's terrible packaging for something so valuable and fragile, and you're totally right to be annoyed, especially after they used the same materials for the replacement! Dumbasses

@Stan-Douglas Although maybe it wouldn't be legally possible, since the water is technically RX-only?

@hunt_ak Just in time

@Commander Are you asking if they have a chat thread, or pricing page, or links to coas, or anything like that? No, they just have the one main "announcement" page, on which Tracy posts the continually-updated price lists, and that's the same page where alerts appear about different warehouses going in and out of stock, or things being on sale.

@Stan-Douglas Ooh, what a great idea. Seconded!

I know Hospira is considered the gold standard for bacteriostatic water, but I'm not a fan of their plastic vials, and in light of all the recent faux-scarcity and price-gouging by Hospira resellers, I felt now might be a good time to compare other options. My goal was to find a brand that 1. packages their reconstitution solution in borosilicate glass instead of plastic, 2. has published testing results available, showing consistently high quality and purity, and 3. manufactures their products in Europe or the USA, rather than in China. Bonus points if they have a seemingly-good reputation online, and lots of positive reviews from fellow researchers, although obviously the latter can be faked or manipulated. The water I eventually selected is made by Parrox, and runs about $5.25 a vial when purchased in quantity with a discount code and free shipping. If you're in Chicago and would like to go in with me on a large-ish order, let me know! If you're not in Chicago, but have been on a similar hunt for Hospira alternatives, maybe check them out for yourself. Shelf life on the vials appears to be 3 years from date of manufacture.

Thanks, I checked it again, the link populated this time, and now I could see an announcement, so I went ahead and joined the new channel. It was empty and sketchy-looking the first time I checked! Always good to have confirmation

@Snake-Pepskin Thanks for that heads up! The most recent results I saw were from tests done in April by Light Labs. PH range was supposed to be between 5 and 7 and Parrox tested right at 7, so technically a pass, but on the upper edge as you noted. I remember seeing good scores for Lamda, and another brand, Quality Research Chemicals, which I ordered through Amazon last autumn, but now I can't find the test page where they compared them.

I started trying at 7:57 but the bot wouldn't let me in until exactly 8:00 EST. I never saw the Tesa listed at all, but still managed to load 4 other types of peps into my cart. Multiple items had already disappeared from inventory after the first 30 seconds. Unfortunately, invoice creation failed during checkout, which forced me to cancel and start over, and by 8:01 hardly anything was available, so when I finally did make my buy, it was just for some Tirzepatide 30mg, which appears to be from the troubled May batch. On a whim I went back later and added a kit of Survo. Here's hoping all my Pubetides arrive contaminant-free! Maz and Survo were still in stock as of early this morning, for $75 each plus $12 shipping

I bought GLP-2 30mg from Certified Peptides twice, when I was first venturing away from tele-health and prescription peps and didn't really know where to look for vendors. At that time they had a good rating on TrustPilot and a few other review platforms (plus maybe someone had recommended them on Reddit?) so it wasn't until later, after I'd already purchased, that I started to spot all the screencaps and anecdotal warnings about the owner's aggressive and antisocial behavior. I realize now that their prices are quite high, and even if he isn't a sex pest, Jason does seem to act like a dick whenever his buyers report a problem, so I doubt I'd shop there again, but my own ordering experience was delightfully calm and trouble-free. Shipping was prompt, communication was adequate and timely, vials were well-packaged, and the peptides performed perfectly both times

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)

Read the full review: Poor experience with Tirzepatide 30mg (kit of 10). Single vial of Reta seems OK

Please keep discussions respectful and factual.

@Newenough It was probably a spoof account, but if you DO want the real Aavant's Maz or Survo, kits of 10 seem to still be available through the bot for $75 +$12ish shipping, which is pretty cheap for domestic
