Exceptional experience
My experience with RCpeptides has been nothing short of exceptional. Very good materials and Boris is an incredibly proactive, friendly and helpful guy. I am recurring user of their services and hope to stay like that for a long time still.

UPDATED: Normal delivery ..
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.

testing and transparency need improvement.
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.
