RCpeptides Reviews 

Good and quik response from Boris. Quik delivery and well packed. Will buy again for sûre.

Updated after additional research beyond my personal experience.

Fast or normal delivery isn’t the only thing that counts.

Delivery: 4 stars

Delivery was acceptable but could have been faster. It took about two days longer than I would consider excellent from dispatch by RC to arrival at our address. This may simply reflect the price and service level chosen from the logistics provider.

Product authenticity: 4 stars

The tested vials contained the purchased product as stated.

Dosage: 5 stars

The available test results showed normal dosage levels.

COA traceability: 1 star

There is no reliable way to match a delivered vial to a specific certificate of analysis. The information on the website cannot be linked to the particular vials received.

Unfortunately, this is common among vendors, but it should not be accepted as good practice. Every vial should carry a batch identifier that can be matched directly to the relevant COA.

Customer support: 5 stars

We initially contacted the wrong email address. When questions are sent to the correct support address, they are answered.

Likelihood of doing business again: 3 stars

RC remains on the shortlist, particularly if the price is competitive or something is needed urgently.

Fast shipping and nice products.

Everything Fine from Order to delivery just 29 hrs
Thank U

I have ordered from this company a few times now and they are very reliable. The shipping is also extremely fast.

Customer service is great and the product is good

The 3 stars are mainly for the fast shipping and quick responses by email.

Unfortunately, the ghk-cu I received was from a different batch than the one tested on their website. I was told the report for my batch would be published soon, but after a few weeks I’m still waiting. Even the label was completely different from the one shown on their website, which may be a small detail, but still affects the overall impression.

I also contacted them about KPV and was told a new report was coming. Once published, the purity result was far below what I personally look for when purchasing peptides, which naturally raised further concerns about the unreported ghk-cu batch I already received.

I’m leaving this as constructive feedback because I think they have potential. For now, I won’t purchase from them again, but I may reconsider in the future if they improve their testing and overall transparency.

Super fast delivery - a joy to transact with - excellent communication.

Great! Highly recommended!

This Shop is legit, fast delivery and good support.

Second time ordering and again, great service like last time. Highly recommended, 11/10!

Insanely impressed with the shipping (1day) and the product quality itself, they put a batch in each vial so you can go confirm yourself it's legit, will be buying more in the future for sure

After researching alot of different vendors I found this website through a closed community.

I placed my order a little over a month ago (10mg retatrutide). Now a month later I placed my 2nd order.

Overall experience so far is good, vials arrive packed well, no fancy multicolor labels, just the required information, all you need.

Always high quality, always fast shipping. The owner is friendly, honest, and helpful. The thank you cards and free BAC are such a kind gesture. Thank you, RC Peptides, for helping folks reach their health goals and live life more fully! 🙌

Very efficient and friendly service. Shipped and arrived overseas in next to no time. Consistent high quality products. I highly recommend.

Super fast and everything seems correct ✅ can’t wait to try the peps

update: finally was able to sort out some misunderstandings and got my order re sent and got it successfully this time! will update in few weeks on the quality after testing out the reta i bought

edit: they answered my email and apologized for the misunderstanding i will edit the review again when my order arrives.

my order got taken by customs after i had already asked if that might be a problem and was told they had shipped to finland before but then instead of them sending my order again free of charge they requested me to buy another order in order to have my lost items sent again?? process has been very confusing and i haven’t gotten any reimbursement or my order atleast sent again for my taken lost vials i already payed for.

FED ex delivery was doing some crap so my neighbors received it. RC itself seems to be very good and legit to me ( ordered enclo earlier and now enclo + Reta
Even got 5mgs extra.
Also the support was great. Fast replies good Service
Will Order again

It's the second time I order from RC peptides and they never dissapoint me, I got the products in 2 days and they gave me a 10 ml bac water for free, they have the COA from a third party testes and their products are as effective as they can be.
The client support is very efficient too, Boris responds in as little as 10 minutes and it's very professional, I asked for 2 COA's and he send it to me rigth away.
I coudn't be more satified
