Nextgen Peptides Reviews

This is my third order from them and they are one of the fastest shippers I've used. Always takes two days to middle Texas assuming I order on a weekday before lunch time. I just wrapped up using a bottle of Reta and currently on their GHK-Cu / KPV blend. Today, my 3rd order consisting of Kisspeptin and TA-1 just arrived. I think this vendor gets a bad wrap because there are two other vendors with similar names and they often get confused. This vendor also has a cult following on Discord. If the products didn't work, they wouldn't have a large following. I've only noticed them testing with ILS labs and they've done a few experiments with them as well such as testing peptides left out in different temperatures. In any case, my experience with them has been exactly as expected and on par with other vendors I have used and honestly these guys have superior pricing, which is one of the main reasons I keep coming back.

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 about a day longer than I'm used to, but I think they were about to move to 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 my 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. I couldn't afford self-funded testing, in fact I barely had enough money for another order, but I decided to set the NextGen product aside, and find a replacement elsewhere. There was a big stink in March about grey vendor GLP-2 that wasn't Tirz at all, and multiple vials from several vendors were testing positive for endotoxins, so considering the 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, I always wondered if I just happened to get a bad batch. I finally reconstituted and researched my single vial of NextGen Reta, in June, and that one seemed fine.

I ordered a bunch of stuff through them over 2 separate orders, but I'm only using two products up to this point (Reta 20mg) and oral 5-amino-1mg + NAD pills. I take the 5-amino+nad before workouts and I notice a little extra in the tank. Not sure about help with body composition as I'm already lean and on Reta, but it can't hurt. The Reta is working just as well as my previous vendor vial. Pricing on everything I bought was very competitive and honestly probably the cheapest in terms of the 5 vendors I like to use. Both orders the shipping was super fast (2 days to TX) and comes in fancy packing, which is becoming more common across vendors now. Would buy from again. They also have a discord with that has occasional special discounts and a few products not listed on the website (not sure why this is the case but SS-31 is an example).

Just got my order from June 6th, insanely fast shipping (got it today June 8th). Credit card payment went through on the website without any issues. Every vial has its own batch number linking straight to the COA library, and you can verify the access code yourself at ILS Labs. Also, worth mentioning that the labs were done in April and May. Honestly, I don't know what happened with the other reviews, but this is my second time buying and zero complaints so far. Great prices and quality, so going to keep ordering from them.

This peptide did absolutely nothing for my research subject. Had it test at a local compounding lab and it was less than 10% Cagri. Waste of money.
