Community Warning!
An independent vendor reviewer (VialVerdict) states HPLC testing and third-party COAs are "available on request only" and "not standard practice", directly contradicting the vendor's own claim of publicly available, per-batch, QR-linked COAs. Independent lab aggregator Finnrick.com has tested only 5 samples covering a single product (Retatrutide), with 1 of 5 failing purity/fill standards. The vendor's official social media presence (Instagram ~36 followers, Facebook ~28 likes) is unusually small for a company claiming 1,500+ Trustpilot reviews. Peptide returns are not accepted at all, and non-peptide returns incur a 15% restocking fee.

Consistent, reliable quality
I have made my 2 or 3rd purchase and the quality is consistent and reliable. I even referred my partner and he has ordered and his friends are ordering as well, about 2-3 of his friends.

Quick and legit product
The ordering process was a breeze and shipping was prompt! My research has shown big changes and effectiveness. COAS match the batch that’s shipped and have had no validity concerns.

They don't speak English
Look at their website FAQ. This is C/P "Why Do Your Guys Payment Methods Change? Tell me this is legit US. More like Mexico or Trashcanistan. Their vials look and feel SO cheap compared to Tailor Made's. Also, the Phenibut HCL caps they sell is likely maltodextrine. It does not work. I know it.

Quality Peptide Products and Fast Shipping
Quality peptide products, reasonable prices, fast shipping, and responsive customer service. I like that their peptides dissolve quickly when reconstituted, that is always a good sign. I have had no issues with the tesamorelin, ipamorelin, BPC-157 capsules, or Melts strips products. The Melts sleep really works, and I noticed a modest boost in energy from the brain fuel, especially good for those mid-afternoon crashes. I did not notice anything with the NAD+ strips, which given the low dose and fact NAD+ is not very bioavailable orally, this was not a surprise. I do wish their amino acid products (such as their B12 and MIC + carnitine/NAD+) came with batch manufacturer dates, as it makes me uncertain as to the origin. I understand they are research peptides but there should still be some manufacturer information available. Lastly, deeper discounts, like 20-30% off would encourage me to buy from them more often. A competitor I use frequently offers 30% off weekend sales so I usually go with them solely for that, but if the prices or deals were comparable, I think Modern Aminos is a bit higher quality, not to mention they ship lightening fast. Love the loyalty points program though. My biggest critique would be items go out of stock frequently and don't seem to return to stock once they go out, so that's been dissapointing because there are several products I've wanted to use for my research (orforglipron drops, MK-677 liquid, etc.) I haven't been able to purchase simply because they are always out of stock. Otherwise, I have had a good experience with this company.

Best Peptide brand imo
Found out about the brand after trying a couple other companies, and this has honestly been the best quality and price combination I've come across so far. The purity and consistency were noticeably better, and I really appreciate that they provide batch specific COAs and third party testing results for transparency. Shipping was fast, everything arrived exactly as expected, and overall the experience has been great. Definitely one of the few brands I've felt comfortable ordering from repeatedly.

Got enclo and bromatane
Got enclo and bromatane. Completely fake. Ive had enclo from other providers I could definitely feel after a couple days. This time nothing. Bromatane was the same. Ive taken nootropics for years and can easily when I try something new, but this was not the case. When I opened the capsules, they're were the same powder and had no taste as other do. Completely fake.

Decent peptides, vials not as full as stated
I've bought stuff on their US website and overall not bad peptides. Though I feel like better could be out there, this company has done pretty good. 4 because vails tend to not be as full as they said they are.
