I only received about half of my package because it was damaged during transit. I contacted the support desk right away, and they responded quickly and immediately sent out a replacement. Mistakes happen, but their customer service was fast, helpful, and professional. I really appreciated how quickly the issue was resolved.

Excellent!

Have been using them for years. Shipping is always very fast, packaging is great, the CC payment process is easy enough, and the customer service is unmatched. Throw in the pricing and rewards and they're easily the best peptide place around.

Extreme Customer Satisfaction

I would give more than five stars if this were an option.

I have ordered several products from this company and have received only the highest quality items at favorable prices in a quick and efficient manner.

I recently had an issue with the payment process and the team reached out immediately to rectify the situation and offered several options to make the transaction as smooth as it gets.

The communication was warm and friendly so I know I wasn't taking to some AI bot and they went out of their way to ensure I was satisfied. I cannot recommend this company enough and will continue to use their services as my go-to.

(I was not compensated in any way for this review. I am simply giving credit when it is deserved.)

Always reliable

I needed to change my order over the weekend and they responded first thing Monday morning before shipping. These guys are always dependable and have the best quality products. This is the ONLY place I buy from.

Hi Chris we rectified the issue with most past clients it was the shippers not doing their job and USPS also losing packages.

Send an email to the help desk if we didn't refund you for the purchase we will give you store credit + some.

We have a new shipping company and things are a lot smoother now.

MISSING $200 OF PRODUCT FROM PEPTIDES ORDER

I recently ordered a variety of peptides. I've had 2 successful orders with the company, so figured I would make a larger one this time. I was supposed to receive 1x Melanotan II, 1x Oxytocin, 1x PT-141, 4x Selank, and 2x DSIP. Instead I simply received one of each of the peptides, leaving me short 3x Selank ($50 each) and 1xDSIP ($30 each) for a total of $180 missing from my order (plus the tax and shipping). I sent messages on the website, via email, and have called as well, but to date, no response. I truly hope they reach out to make the order fully complete and I get to change this review accordingly, but with the current lack of communication from their company, I am not sure that will take place.
