Rivn Peptides is the 3rd distributor I have gone through, & I have nothing but positive things to say about this company. Your package arrives & it already stands out more than others. You can tell that they put time & effort into sending out your package verses just fulfilling an order. EVERYTHING is labeled & they even provide a complimentary syringe, as well as bac water to reconstitute your peptides. If you're new to the peptide world, you wouldn't know that you need to reconstitute your peptides or need a separate syringe to properly mix peptides. Rivn sets you up for success. The customer service is very communicative & accessible 24/7. They 3rd party test their peptides regularly & offer COA, so you know exactly what you're putting into your body. The purity level & prices are out of this world. I am very grateful to have come across Rivn. They have a customer for life!

The ordering process is fast and easy but biggest thing is quality of product. With how many wannabe vendors there are, it’s nice to know there is a legit company out there that has a quality product and stands behind it.

Excellent company. Shipping was same day. Prices are unbeatable 😊. Packaging is top notch! COA certifies are easily accessible on the website which gives me peace of mind. I have been using another supplier, but between shipping prices, insurance, and increase cost it was getting ridiculous. Will order again and recommend to friends.

My experience was good overall. The water being free seems like a given since you need it. They ship promptly and delivered in a secure package. The prices seem fair. Overall I'm happy with the products.
