I was amazed of how fast they responded to my email. I emailed them at 10pm Friday and they called me at 10:05 pm that same night. Never have I gotten such a fast response and great customer support from no other company of any kind of product. And the best part was that the owner called me and was so informative, friendly, and helpful. I give them 1000⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️…………….

Daisy J.
I’m genuinely very happy with this purchase. Everything arrived quickly, and the product is exactly as expected, excellent quality and a seamless experience from start to finish. I couldn’t be more satisfied and will absolutely be ordering again.
Response from PeptideGiantsApr 30, 2026
Daisy, this honestly means a lot—thank you for taking the time to leave a genuine review like this. You wouldn’t believe how much of a hustle it can be for small research-only companies like ours to even get real feedback posted—and honestly, what it takes just to make sure a review doesn’t get removed or flagged. So we truly appreciate you going out of your way. It really helps more than you know. We’re glad everything arrived quickly and exactly as expected—that’s always our goal. We work hard behind the scenes every day to keep things running smoothly and make sure our customers have the best experience possible. We’re here to stay, and customers like you are the reason why. Looking forward to your next order—and if you ever want an extra discount, just reach out and ask. We’ve got you. Thank you again, Peptide Giants 💪
Robert A.
Great customer service. The quality is above what I expected. Highly recommend them for your peptides. Now problem with the caps. Just pop them off. Don’t try to work them off slowly. This will make anyone’s seal tear. Watch a YouTube video if you are unsure of anything.
Response from PeptideGiantsApr 30, 2026
Hi Robert, Thank you for the kind words — we’re glad to hear you were happy with the quality and overall service. We really appreciate your feedback. Just to clarify on the vial tops, as this can be confusing — there are generally two types used in laboratory supply packaging. Some vials have standard crimp tops designed for single access, while others (often marked with a small arrow) are designed for use with compatible laboratory dispensing devices. With the latter, the aluminum seal is not intended to be fully removed. Applying too much force or pressure while attempting to remove it can cause the top to release suddenly — similar to a pressure pop — which may be what you experienced. There isn’t always clear guidance available on this, so it’s a common misunderstanding and something we try to help clarify when possible. As always, all of our products are intended strictly for research and laboratory use only. If you ever have questions about handling or packaging, feel free to reach out — we’re always happy to help. Thank you again for your support. Bruno Peptide Giants
