Great to hear the service has been consistently first rate.
Very Impressed
Email replies, order confirmation and delivery is extremely prompt. The information provided is clear and most importantly, the peptides are third party tested. There has clearly been a lot of thought and effort put into River Peptides - an efficient and transparent supplier.

Meh delivery - too early to review the product
Delivery was done in time, as Royal Mail is taking care of it. Packaging was horrible and half opened with no instructions and only a QR code taking me to the site with a half assed YouTube video. It’s 2026, I’m sure you can embed a video on your site.
I can’t be certain for the product as it’s only been 3 days.

Thank you for taking the time to leave feedback.
We’re sorry to hear that the packaging and information provided didn’t meet expectations. All orders are packed securely, and any protective cases or seals are included as standard to ensure items arrive safely.
As a research supplier, we’re limited in the type of instructions and guidance we can provide publicly, which is why we direct customers to general information via our website. That said, we do take comments like this on board and are always reviewing how we can improve clarity and presentation within those constraints.
We appreciate you raising your concerns and will use the feedback to continue refining our processes.
Great customer service

I have had sprays from other places and felt the effects. However, they have since closed. I have purchased four different sprays from this company and felt nothing at all. It is literally like spraying water into my nose. I personally would not recommend them. I reached out to the people in charge via chat and the response was disappointing. I would like to see the purity reports for the Selank, Semax, PT-141 and DSIP. I am very disappointed.

Thank you for taking the time to leave feedback. We’re sorry to hear that your experience didn’t meet expectations.
We did respond directly to your enquiry and always aim to be transparent and factual when discussing our products. Our support team follows the same process for all enquiries, and as a research supplier, all compounds are provided strictly for laboratory research purposes, which limits what we can comment on publicly. Individual perceptions and expectations can vary.
Documentation relating to analytical testing and quality is available through the appropriate channels, and we’re always happy to continue the conversation privately to provide clarification where possible.
We appreciate you raising your concerns and take all feedback seriously as we continue to improve our service.
