All three tested products received a 'BAD' designation with scores of 3.0/10 and an overall 'E' (Poor) rating.

Phenomenal products and customer value!
Phenomenal products and customer value! This Company and their products are amazing! They truly stand behind their "Oath". The Companies dedication to delivering high quality products that are lab tested, then must go through a ridged approval process prior to distributing to their valued customers is unsurpassed!

Heat-damaged order replaced fast
Great experience with Oath Research (oathresearch.com). My first order ran into a shipping issue — the product arrived in rough shape after spending too long on the delivery truck in Tucson's summer heat. I reached out, and they handled it without any hassle: quick to respond, easy to work with, and they shipped a replacement fast. One tip I'd pass along to anyone ordering to a hot climate: I had the replacement shipped to a local UPS Store for hold-for-pickup instead of my home address. Same 100°+ Tucson weather, but because it spent far less time sitting on the truck and went straight into an air-conditioned store, it arrived in much better condition. Made a real difference. Oath Research stood behind their product and took care of me when something went sideways. Fast shipping, great communication, and an easy resolution. Earned a repeat customer — highly recommend.

This shit is real
I had been seeing so many differnt things about peptides, how well they work, and how they could "change your life" and I was intrigued, but for the amount of good things I read and heard about the peptide industry, I heard an equal amount of horrible things. The scams, the fake peptides, etc.... so I had claude look up the best peptide companies for reta lol... and oath popped up. I had it look at reviews, their COAs, I even went to the website of the company that test OATH's peptides, just make sure it was all real... and once I had enough info, I ordered it. It took about 3 days, but thats becuase I ordered it in the middle of the night. Once it arrived I was skeptical as hell, but the packaging was nice. To make a long story short, I injected that shit (started with 2mg's) On the first day didnt feel anything, on the second I barely ate... Im now on day 3, appetite is close to minimal... Im writing so you all can save the trouble of wondering if they are scam, or if itll work for you... it will, lol.

OATH: Not just a tag-line - REAL DEAL 100% tested, reliable, responsive and fast shipping.
OATH is 100% above board and worthy of your business when seeking peptide products. OATH products are tested and reliable, coupled with excellent customer service and fast shipping - even the packaging is impressive. Lots of peptide companies out there, but OATH makes all their batch data public with published Certificate of Analysis' (Independent laboratory testing confirms purity and composition of their research peptides). Customer service? EXCELLENT; responsive and professional: Thank You Greg! Do your research and you'll see OATH is a top-shelf company. RELIABLE / FRICTIONLESS / RESPONSIVE / FAST SHIPPING

Order concern handled with a call
Not sure why I slept on this company for so long. Had concerns with my order, sent an email and received a call from Oath. Was assured of my concern and more. ⭐️⭐️⭐️⭐️⭐️ I also really like the aesthetic of the company and packaging was top notch.
