Thank you for your support and for sharing your experience — we really appreciate it.

We understand how frustrating this situation is. We replied to all emails and also sent a mass email explaining that the shipping carrier unfortunately lost a large number of packages, which is why some orders only show “label created.”

Because we don’t want our customers to be affected by this, we are reshipping all missing orders at our own expense, even though we are not receiving any compensation from the carrier.

We’re very sorry for the delay and are doing everything we can to get your order to you as soon as possible. If you have any questions, please feel free to contact us anytime.

Great responsivenes

I ordered just before X-mass so I guess my parcel got lost by PostNL. Boris was very responsive when sending him emails and ended up sending the order again and even promised to ad some free goodie for a future order. It is great to be able to connect and get responses quickly when you are concerned about the your order, that is really not the case everywhere. Looking forward to try the peptides now. :)

Absolutely amazing customer service

Absolutely amazing customer service. Me and Boris have emailed eachother back and forth and he is super nice and very helpful. Email response time is very good too. Unfortunately my package got lost but he resent the package for free and even upgraded the peptide amount. Very professional and reliable. They provide batch-specific COA's which is very good and they test their product for purity.

Reliable, kind and good hearted!

They have good and very personal customer service. With peptides it takes time, so I can't leave instant result review, but from what I see and feel I can vouch they are thrustworthy and I will order from them in the future!

First of all, all product keys are clearly listed on our website under “Latest Test Results.” The information you mention is publicly available and transparent.

Secondly, could you please let us know which email address you used to contact us?.

Lastly, according to our records, you have not purchased or used our product. We believe it is only fair to try a product before leaving a review. Constructive feedback is always welcome, but leaving a negative review without firsthand experience is misleading.

If you decide to try our service in the future, we would be happy to assist you.

Kind regards,

Borid

Outstanding customer service – highly recommended

I have ordered from RC Peptides three times, and unfortunately the third package was lost by PostNL.
Despite this, the support I received was absolutely outstanding.

I was in constant contact with Boris, who handled the situation in a very professional, friendly, and reliable manner. In the end, he personally made sure that my entire order was resent at his own cost, completely free of charge, and it arrived safely.

This level of customer service is rare and definitely not something you can take for granted. Communication was fast, clear, and solution-oriented from start to finish.

I can highly recommend RC Peptides – not only for the product quality, but especially for the integrity and customer support behind the company.
Thank you again, Boris!
