Ordered reta as problem with Tirz, Reta came straight away, Tirz was/is out of stock but they sent me one of the last ones left with free Bac water and I’ve no doubt I’ll receive the other two in the coming days, really well presented, any research so far has proven fine, would recommend no problem.

Sadly I only recieved half of my order and after many emails requesting the missing item which they said would be sent out nothing was recieved and was ghosted by customer service

On my 4th order, great prices, fast shipping, legit quality and top notch customer service! I just wish they had GHK-cu and some oral versions as well. Reta, BPC, TB, MT2 👌 I’ll be back as long as they are up and running

After researching for a while I found peptide worldwide couldn't be beat on pricing and I gave them a try. Products came in and reconstituted nicely, but only the bpc 157 and cjc 1295 no-dac had a vacuum. Tb-500, epitalon, ipamorelin and melanotanII had no vacuum. Being new to this, I don't know how big of a deal this is and am using the products anyways without any noticeable side effects. Will probably order again.

I have placed several orders with Peptideworldwide and have found it to be an excellent company. The ordering process is straightforward, and the delivery is impressively quick.

They are also very accessible for any inquiries. I will certainly keep ordering from them in the future.

Thanks guys !

Ordered twice now, product is good value and reliable, I've been using their Bpc157 and Tb500 with good results. Shipping is fast enough normally a few days.
