Gary is totally Legit. I’ve had to have 2 returns (all my fault) and Gary has been true to his word in refunding me. On top of that, his peptides are also legit!! Thanks so much Gary!!

Support is awesome and they go above and beyond to ship fast quality products. Very happy with my ex

Support is awesome and they go above and beyond to ship fast quality products. Very happy with my experience with Penguin Peptides and have made multiple purchases. On my first order we were pleasantly surprised to get a special promo with a 10 vial storage case with an ice pack. Nice touch. Love this company.

Updated Certificate of Analysis meets purity standards, but lacks some testing info

The recently updated Certificate of Analysis aligns with their purity standards, but I can't locate any details about endotoxin or heavy metal contamination testing. Their products are legitimate and competitively priced, yet I don't feel the same level of certainty as with other brands. While it would take significant negligence to allow such toxins to be present, they would gain more trust by offering that type of testing.

Consistent Fast Shipping and Great Support

I've placed more than a dozen orders, and the shipping has consistently been quick; being in California, I receive my orders within three days. On one occasion, they missed including a peptide, but the support team responded to my email the same day and promptly shipped it. I have an autoimmune condition, and the peptides I’ve purchased have significantly helped me. While I'm still learning about their purity, I have been satisfied with my experience so far.

Shipping is fast but no results

Shipping is great and fast but after using for several months and at 7.5mg tirzepatide I haven't lost any weight. Plan to go up to 10mg next week but not hopeful. So disappointing.

Spooky fast delivery!

Shipped fast, well packaged, and quality products. They are always running different sales which makes it easy to try new products and stock up on my monthly usuals for the best price.

Consider this….

I have significant spinal issues from military service and rely on a spinal cord stimulator, periodic steroid injections, and chiropractic therapy, and I’m frustrated with my condition. I've tried BPC157/TB500, which, while not a miracle cure, has notably improved my sleep and reduced stiffness and discomfort. I find this combination almost as effective as my spinal cord stimulator. I wake up feeling refreshed and I can’t tell you the last time that has happened. If you are in otherwise good health and you need to stop your pain cycle, maybe consider this combo.
