On point

Ordered 10 mg Reta, package lost for a problem with the shipment, Boris arranged himself the new delivery and sent a 40mg vial with BAC free, I have to say the service is impeccable, I will order again. After 2 weeks my lab rat noticed huge appetite suppression especially, with noticeable amount of fat loss.

It's been a week since my shipment was…

It's been a week since my shipment was marked as sent. However, it never arrived at PostNL. I had this issue before and Boris resolved it. Maybe he's not available at the moment as I haven't been able to get a reply from him for the last 3 days.

Update: Boris contacted me and will resend. Regarding feedback "that the emails were sent over the weekend"and "Boris had already arranged the reshipment before the initial review was posted." Unfortunately, I didn't get any e-mails. So for everyone else out there, be more patient than me, Boris is fixing everything 😉

I also see now that shipment was received by carrier March 24th. So everything looks good now 👍

Thank you very much for your continued support and for taking the time to share your update — we truly appreciate it.

We would like to clarify that the emails were sent over the weekend, which may have caused a slight delay in response time. However, Boris had already arranged the reshipment before the initial review was posted.

We’re very glad to hear that everything is now being resolved, and we sincerely appreciate your patience and understanding throughout the process.

Warm regards,
RC Peptides Team

First order

This was my first time ordering here. Unfortunately, there was a glitch with the payment, but customer service was very helpful. Delivery was very fast. I even got a little bonus with my order—thanks again for that. 🤗 The peptides dissolve nicely, and the solution is clear. The selection is huge. This definitely won’t be my last order.

Hello Boris

I have ordered twice of Rcpeptides Boris is legit and the product is good. First order went very smoothly, the second one had a lot of problems, problems that Boris can’t control, product being damaged and lost. Boris being very kind offered free reship, but now he doesn’t answer my emails and I assume nothing has been shipped. I just want to write this so I can know if I need to buy the product again or just wait, Been a long time now.

Update: What a guy Boris, Gave me free reship after countless mistakes from delivery, All Love

Great products, great Prices and excellent customer care

Been buying on here for quite a while now and always a pleasent and fast experience. All products which I bought (HCG, Retatrutide, Ru58841) all are genuine and some of them dosed stronger than advertised. When issues happened because of the post. Boris was fast in responding with a solution and last time it happened had also a gift included; even tough the fault was with the post. Highly recommend vast selection of products, great prices and above all if issues arise they will always help you.

good products on a fair price

I’m writing this review because I’ve ordered from rcpeptides.com several times and my experience has been very positive. I’ve tried different products and all of them have worked very well according to my expectations.

In my last order there was a mix-up with the shipment, but the support team handled it quickly. The correct product was sent out again right away. They also allowed me to keep the product that was sent by mistake as a gift.

Overall, I’m very satisfied with the service and communication. I would recommend the site to anyone interested in research products.

My honest opinion

I’ve ordered from RC Peptides multiple times now and I honestly only have positive experiences. Every order arrives well packed and they even include a handwritten card, which is a really nice personal touch that you rarely see anymore. On several occasions I also received extra milligrams or even completely free products, which really shows they appreciate their customers. What also stands out is the customer service, because whenever I send an email I always get a quick and friendly response. My last order actually got lost during shipping, which of course can happen sometimes, but the way they handled it was impressive. As soon as I contacted them they immediately took action and sent a replacement free of charge, and on top of that they even upgraded my 10 mg Retatrutide to 30 mg, which was completely unexpected and very generous. Because of experiences like this I honestly don’t really understand some of the negative reviews, since in my experience they are always friendly, helpful, and any issues get solved quickly. But I guess that’s just how it is sometimes, there will always be a few sour apples out there. Highly recommended from my side :)

Hi Kevryn,

For that reason, we’re sending our response to you again below so you can review the information regarding your shipment and we can help resolve this as quickly as possible.

Please be assured that we will resend all lost packages free of charge. You do not need to take any action. We are in direct contact with the parcel service to identify exactly which shipments were lost, and we are also arranging upgrades to compensate for the inconvenience.

Order received

I placed an order on February 22 (Order #3365). I received the confirmation email, and about a week later I was informed that the package had been lost, which I found quite unusual. I was then told that a replacement order would be sent on Thursday since the original one had been lost.

However, as of today I have not received any confirmation, no tracking number, and I am still waiting for the order. It’s quite disappointing because I was really excited to place my first order after reading many positive reviews, but at this point I’m not sure what to expect.

UPDATE: Thank you for the update regarding my order. I will be more than happy to update my review once I have received it. Thank you, and I will be waiting for its arrival.

UPDATE: I just checked the tracking and it shows that postNL has received it! Thank you! I will update once I my order

UPDATE: I just received my order! I’m super happy, and I event received extra reatrutide. Thank you Boris :)

Hi Domenica,

We completely understand your frustration and we’re sorry that this situation has been disappointing, especially since you were excited about placing your first order.

As mentioned in our previous messages via WhatsApp and email, we have been continuously assisting you and keeping you updated throughout the process. Unfortunately, the original package was reported lost by the carrier, which is why we immediately arranged a replacement for you.

Your order has already been resent, free of charge, and we even included some upgrades for the inconvenience. We truly did our best to resolve this as quickly and smoothly as possible.

If you have any further questions, please feel free to let us know.

Kind regards,
Boris

Thanks for the sticking with us my friend :)

Package was lost, found and upgraded :)

Everything was fine with the first order. Now my second order was announced to be shipped but never made it to the shipping company. I haven't received any response to my mails or support tickets since a week. Shipping info wasn't updated or has changed, nor did I receive any explanation what's the reason of the delay or get my money back.

UPDATE: I didn't receive any mail from them and no one answers to any communication except here. Please check order number #3367, there was no mail. It's more than frustrating that there is no communication, I dont know if they just cant handle their service properly or if it is a scam.

SECOND UPDATE: There seems to be something happening :) A parcel is apparently on its way.
Will update when it has arrived.

Hey Boris, I really appreciate your updates here, but please check your e-mail client, I swear I haven't received any of these mails. I also double checked everything, including spam mails and my mail address in your system, so it should be absolutely possible to get mails from you. Somebody else here claimed, that he doesn't get your mails too, so maybe it is just an IT failure.

FINAL UPDATE:
Got my parcel and got a free upgrade on my order, thanks a lot Boris :)
So everything is fine, can recommend 👍

Thank you for your support and for sharing your experience. We completely understand your frustration, especially since your first order went smoothly.

We would like to mention that we have responded to all emails. In addition, we also sent an email to all customers explaining that the shipping carrier unfortunately lost entire days of shipments. Because we do not want our customers to be the victims of this situation, we decided to reship all affected orders free of charge.

The free reshipment of your order has already left our facility. We have also sent the email again directly to your address, including a personal one-time discount code as a small gesture for the inconvenience.

Once again, our apologies for the inconvenience and thank you for your patience and support.

UPDATE.
Since our emails do not reach you apparently. Emails are stated down below :)

Regarding the communication: we have noticed that in some cases our emails unfortunately do not arrive. This usually happens when the email address in our system does not exactly match the one used during the order, or when email providers incorrectly flag our messages as spam, meaning they may not appear in the inbox (and sometimes not even in the spam folder).

I’ve ordered from RCPeptides many times…

I’ve ordered from RCPeptides many times before and everything always went perfectly, so when my latest order had an issue it was the first time I ever experienced a problem. My track & trace stayed stuck on “label created, not at PostNL yet,” and it turned out the package had been lost by the shipping carrier. As soon as I contacted their customer service, they replied almost immediately and opened a case with PostNL right away. Within two days I got an update that the package was officially lost, but they were already arranging a completely free replacement order for me. That level of service is something I honestly haven’t seen in a long time. Super professional, fast, and very customer-focused. Highly recommended! ⭐⭐⭐⭐⭐

Amazing customer support

I recently ordered from RCPeptides and unfortunately my package got lost by the shipping carrier. I was really worried at first, but their customer service responded incredibly fast and was very kind and helpful throughout the whole process. Without any hassle, they arranged a free reshipment for me and made sure everything was taken care of.

It’s rare to find a company that stands behind their customers like this, and the whole experience turned out great in the end. I’ll definitely be ordering again. :)
