Our contact information is on our website, however for a faster response customers can reach us by email for assistance. We strive to respond as quickly as possible and resolve any issues that arise.
We appreciate your interest in the promotion and hope you'll give us another opportunity to assist you in the future.
Customer service was great
Customer service was great! I had an issue with shipping, at no fault of sjp peptides. I made contact with them and they went out of their way to fix it. Thank you.

I feel that the website is easy to find what I am looking for to order. Unfortunately it is hard to the site to accept accepting my payment. OK

Not all of order received
Would have given more stars if I would have received the needles I ordered and paid for as well. Product is good, if you get all that you ordered 😂

Thank you for your feedback and for your comments about the quality of our products.
We're sorry to hear that you believe an item was missing from your order. However, we're disappointed that a 3-star review was left without first reaching out to our support team or submitting a missing-item claim through our website. We take order accuracy seriously and have procedures in place to investigate and resolve these types of issues when they occur.
If an item was missing, we would have welcomed the opportunity to review your order, packing records, and shipment details so we could make things right if an error occurred. Unfortunately, this is the first time we are hearing about the issue through your review.
Please contact our support team or submit a claim through our website, and we'll be happy to look into the matter for you.
We appreciate your business and look forward to assisting you.

Best place for research and high quality products
Best place for research and all the products are phenomenal!! Shipping is always fast, and the quality of the products are top of the line, and amazing, along with pricing. I’ve been a loyal customer since September of 2025, and Sjpeptides is the only company I use and trust for research. I can’t wait to try out their skincare next 🖤

I’ve had a great experience with SJ Peptides. Their transparency and commitment to quality really stand out. Shipping is always on time — and sometimes even earlier than expected — which is a huge plus. Their prices are very reasonable for the quality of the products they provide. Every product I’ve received has been high quality and exactly as described. Customer service has also been excellent anytime I’ve had questions, and their website is easy to navigate with a smooth, hassle-free payment process. Overall, SJ Peptides has been reliable, professional, and consistently delivers a great customer experience.
