Review

I have purchased peptides from 3 different companies now and had a great buying and customer service experience with all 3.

This company is no exception. For that, they get 2 stars.

However, after purchasing GLP# as well as CJC1295+Ipamorelin (noDACS) from other companies with great results the first time, I knew what to expect from a good product.

I came across a deal via Peptide Critic for the (supposedly) same item at GenPeptides, so I purchased these items again through this company, as a 'bundle'. Great deal - if it works as advertised.

Before purchasing, I submitted the lab report for verification and it came back positive. However, after running it through AI, it pointed out that there were some pretty important gaps in the lab results compared to all other competitors I had previously used. After I inquired with the company, their response was: "Batch-specific sterility and endotoxin testing were not performed, so we cannot provide results or make batch-specific sterility or endotoxin claims. Additionally, we do not perform heavy metal testing."

This was a little concerning to me but I went ahead with the purchase.

I began using the product a day or so after receiving, reconstituting identically to my previous items, and I can report that after 3-weeks, the effects just aren't there. Even increased doses see zero response.

Maybe it works for others, but I'm not having any luck with products from this company.

Hi,

Thank you for sharing your experience. We appreciate the positive comments regarding your customer service experience. However, we wish to clarify factual points in your review:

First, our records do not match the timeline your shared. Your order was placed on July 16, 2026, and delivered by UPS on July 22, 2026. You sent your questions regarding the COA on July 27, 2026, five days after delivery.

Your review states that you “went ahead with the purchase” after contacting us. That sequence is not accurate. The order was delivered to you five days prior to you reaching out.

Second, regarding your reported results: we are sorry that your research is not meeting your expectations. Please note that individual reported outcomes do not establish the purity, identity or content of a product. Those are established through laboratory testing, which we provide with every batch. Reasons for your research outcomes may include your selected research protocol, especially if it involves a product that requires increasing the research amount at regular intervals.

We welcome scrutiny into our company, but we ask that the timeline be accurately represented. Please note, our COAs are readily available at the time of purchase, and we welcome customer questions regarding the COAs.

I think the site looks great, and I love that the COAs are available right there above every product! I'll be putting in an order.

I am not sure about this company. There is user @Geno that praises this company at every occasion, looks suspicious. I added it to favorites, then removed. Maybe more people need to take a look.
