Good quality, fast shipping

Ordered Epitalon and NAD+. Arrived in 3 days. Packaging was discreet. Quality seems fine. No issues.

Reliable source for peptides

This was my fourth order from Zesty Rat Research, and they're still consistent. I got the BPC-157 and TB-500 again. Shipping took about 5 days to get to me in Florida, which is standard. The product quality seems to be the same as my previous purchases, which is why I keep coming back. Only minor thing is the website can be a bit slow sometimes during peak hours.

Reliable source for research needs

This was my fourth order from Zesty Rat Research. I got some Semaglutide this time, and like before, the purity was as expected based on their COAs. I've used them for various compounds over the past year, and they've always been consistent. Shipping took 5 days to reach Arizona this time, which is about average for them. I wish they had more payment options besides crypto and cards.

So happy with my order!

Oh my goodness, I just received my order of Semaglutide and it arrived so fast! Everything was packaged perfectly and securely. I was a bit nervous since it was my first time ordering from them, but wow, I'm genuinely impressed! The quality looks really good, just as described. I'm definitely going to be a repeat customer here. My only tiny feedback would be adding more detailed descriptions for some of the lesser-known compounds, but overall, fantastic experience!

Decent overall, few hiccups

I ordered some Melanotan II and PT-141. Shipping was a bit slower than expected, took 6 days to reach Austin. Packaging was good and discreet, which I appreciate. The products themselves seem to be of good quality, no complaints there. Customer service was responsive when I inquired about the shipping delay, but it would be great if tracking updates were more frequent. Value for money is fair, but I'd like to see more payment options beyond crypto and cards.

Excellent experience with Tesamorelin!

I just received my Tesamorelin from Zesty Rat Research and I'm super happy with it! The product came quickly, even with standard shipping, and it was packed really well. The website was easy to navigate when I placed my order. I appreciate that they provide COAs right on the product page. I'll definitely be coming back for more supplies! The only small thing is I had a question and customer service took a day to get back to me, but the answer was helpful.

Good product, quick shipping

I ordered some BPC-157 last week. It shipped fast and arrived in 3 days. Quality seems consistent. The packaging could be a bit more discreet, but otherwise, everything was fine.

Got my Epitalon, all good

So, I grabbed some Epitalon from here, just trying it out. It came in a decent amount of time, like a week or so after I ordered, which is pretty standard. Everything looked legit when it arrived. The whole process was pretty chill, no major fuss. Just wish they'd send tracking updates a bit sooner after purchase, felt a little in the dark for a day or two.
