About this compound

What is IGF-1 LR3?

IGF-1 LR3, also called Long R3 IGF-1, is a modified form of insulin-like growth factor 1, designed to bind less readily to IGF-binding proteins. It acts on the IGF-1 receptor, which drives signaling involved in cellular growth, differentiation, metabolism, and tissue development.

★★★★★ Rob G.

High purity USA made products. Wouldn't trust anything less, especially when it comes to peptides you have to be cautious.

★★★★★ Amanda P.

Super consistent quality with Zova. Probably have spent close to $1k with them and have had no issues at all.

★★★★★ Liz R.

Ordered on a Monday and my peps got to me on Wednesday. Nice packaging, overall just great experience from purchase to delivery. Excited to put these peppers to use.

★★★★★ Owen B.

Really happy with the quality of these peps. They have the COA to back up the purity too, which is huge. Bunch of these companies throw false claims left and right, so its good to find one thats legit.

★★★★★ Elena R.

BOGO reta might honestly be the best thing to happen to me, LOL. Saw the facebook ad and had to check em out. I'm seriously glad I found these guys, would recommend.

★★★★★ Tyler H.

Their reta is the real deal. Haven't looked back since purchasing. Great customer service as well when I had some storage confusion.

★★★★★ Adam B.

One of the few USA made peptide companies around. Would recommend to anyone looking to start.

★★★★★ Morgan P.

They've been my go-to pep supplier for about seven months now. I started ordering from them at the beginning of 2026 and haven't had any issues. At this point, I honestly wouldn't use anyone else.

★★★★★ Alex S.

Fast shipping, great products, and even better price! Will continue to buy Zova labs products going forward.

★★★★★ Raymond L

Great products with great results. Me and my families go to for all our peptide needs.

★★★★★ Katherine T.

I have ordered from Zova three times in the last few months. They provide consistent products, fast shipping, and great customer service.

★★★★★ Priya N.

This site has best prices I've seen while still having COA's and USA made products. Will definitely be coming back for more.

★★★★★ Marco J.

Top-quality stuff, nothing much more to say. Highly recommend to all fellow peptide users. Owners are some good guys as well.

★★★★★ Heather M.

My peptide source since 2025. This brand has grown a lot since then, but quality has stayed the same, which is nice to see.

★★★★★ Reese S.

Exceptional quality, tremendous results, fast shipping, and great packaging. Wouldn't want to buy from anywhere else, Zova is legit.

★★★★★ Nadia S.

Stocked up on some peptides a few weeks ago from here, haven't had any issues. Was nice to get a free bac water with my order as well.

★★★★★ Alena M.

Best source of Reta out there. I would recommend for anyone looking to get into peptides. 10/10 products.

★★★★★ Jason M.

Been buying from Zova since January. Great products and great overall brand. Won't use anyone else.

★★★★★ Leah T.

Had to get the BOGO reta to stock up for the winter. I can confirm Zova is definitely legit.

★★★★★ Caitlin H.

Would recommend this company to anyone. Timely delivery and the best quality products I have used yet. I have already ordered twice and cannot wait to continue using their products.

★★★★★ Laura J.

Peptides can really change many aspects of your life depending on how you use them. This right here is a quality source.

★★★★★ Jared N.

This is a company that focuses on quality from start to finish. You can just see it in the website. One of my buddies is a part owner, and he's quite the perfectionist to say the least.

★★★★★ Olivia P.

The company is affordable and reliable. 10/10
