Terrible experience

Terrible experience. They didn't send me the product No label, bottle without identification, they don't answer my emails, they won't refund my money, and the product wasn't used because a company that doesn't even bother to respond to its customers isn't serious. Don't buy from him, because the product is questionable.

Do not buy from this company- dangerous

Do not buy from this company. I ordered IGF-1 LR3 and it came in a different vial ad to what was advertised with the vial having residue on the outside. The Bacteriostatic water I ordered came without a label and identification which is incredibly concerning and again, it came in a different vail as to what was advertised. The order also came without an authentication slip. The company claim all their peptides are 99% purity, however if you look at the digital authentication slip when viewing IGF-1 LR3 it is under 99% purity. The company also claim to have a 99% purity garuntee or you get your money back. I contacted the customer service team to discuss a refund and after sending evidence and giving a week for them to respond they have completely ignored me. Another individual from the company reached out to check in on the order. I replied and stated the issues and was ignored again. Please do not buy from this company- you dont know what you are buying is actually what you ordered which raises serious concerns about safety and their customer service team is appalling and completely unhelpful.

Quick order and effective peptides

The order arrived quickly but one of the bottles had leaked.The team offered to send me a replacement and a very generous voucher. I've been taking peptides for the past 10 years and found that my gut, skin and joints are definitely in better condition. The Glow Stack I ordered seemed to work very well, my hair and skin look healthy and the recovery was faster after intense physical days.

No temperature controlled packaging

The item was sent inside a plain bubble packet on some of the hottest days of the year. As peptides are destroyed by heat this makes the product useless

They claim on their website that:

Do you ship temperature-controlled?
Yes. All peptides are lyophilised and dispatched with ice-gel packs in insulated mailers. Free temperature-controlled delivery is included on all UK orders.

This is a blatant lie.

I love using peptides

I love using peptides. They having a real good effect on my body.
Used in the right way with the correct research they can be life changing for some people. Others it just makes good sense! UK peptides have always delivered a good product with no fuss on time so I use them a lot.
