River Peptides Review
River Peptides Review
Been using SLANK and DSIP from River Peptides and honestly very impressed.
SLANK has been amazing for my anxiety — helps keep me relaxed and calm.
DSIP has improved my sleep massively. I’m getting 7+ hours sleep and not waking up 3–4 times a night anymore.
Been a terrible sleeper for the last 20+ years,
Very pleased with the quality and results.
Currently ordered Mot c and copper pep, & another selank 👍🏼

possible side effects
I purchased the MOTS-C 10mg Spray and the DSIP 5mg Spray . The company itself seems reliable and shipping was fine, but unfortunately both peptide sprays caused severe dryness in my nose almost immediately. After only 1–2 uses, I became sick and developed sinusitis, which I normally never suffer from. Just sharing my experience so others can be aware of possible side effects.

Thank you Melanie, really appreciate the kind words and the 10/10 review. Glad to hear you were happy with both the support and delivery speed. Thank you for choosing River Peptides.
WOW!
WOW!
Was searching diligently for a BPC 157 + TB 500 Pen - found a seller - but something seemed off. Too flashy, no signs of testing - and very cheap.
Researched more and come across River Peptides. Everything seemed very professional and crucially the testing was there.
Contacted, asked a million questions and all were answered in detail and with patience.
Purchase process was smooth through the website, and even when our friends at RM messed up - communication was on point and everything rectified immediately.
More patience once the pen arrived and I had further questions!
Will definitely be recommending and using in future.

Glad to hear the service and support stood out.
Customer Service is second to none, with quick postage
Purchased 2 lots of CJC and Ipamorelin, as well as Kisspeptin
The customer service was second to none and I can confidently say I haven't seen customer service quite like it!
I had my order 24 hours after purchase, fully tracked along the way!
Genuinely no need for me to shop elsewhere now, thanks River!

A place for complete Peace of Mind
River at "River Peptides" is one of the kindest ,informative and patient person that I've ever had the privilege purchasing products from. There are a lot of non-authentic peptide companies out there. My word may not be enough, but I was exactly in that position. I honestly say to anyone in that position please use this company to really have that piece of mind and join a community that really cares

Using Selank nasal spray
Using Selank nasal spray. Game changer for anyone with anxiety. My nervous system is stuck in fight or flight. I've tried all kinds. From head zappers, adaptogens, cannabis oil (super strength), pilates, whole plant diet, HRT, to vagal nerve simulators... probably loads more that I can't think of... Trusted company. Love that their products are 3rd party tested. Five stars from me

Glad the service came across as professional.
I’ve been using the CJC-1295 /Ipamorelin blend and IGF-1
I’ve been using the CJC-1295 + Ipamorelin blend, and honestly, the difference in how I feel alone is worth it better sleep, improved recovery, and a noticeable boost in overall wellbeing.
But when I added IGF-1 LR3, that’s when things really stepped up. It went from just feeling better to actually seeing physical changes happen faster.As a woman in her 50s and perimenopausal this stack has been particularly impactful. It’s helped support muscle preservation (which is so important during hormonal changes), while also improving my energy levels and recovery time between workouts.
Over time, I’ve noticed:
Increased lean muscle development
Better muscle fullness and tone
Gradual fat reduction
A tighter, more athletic look overall
Improved sleep quality, likely from the growth hormone support
This combination doesn’t feel extreme or overwhelming — it feels supportive, especially for where my body is at now. It’s been a solid addition to my routine and has helped me feel stronger, leaner, and more confident.
Highly recommend for anyone 40+ looking to support their body through this phase while still making real progress.
