After having some poor experiences with other suppliers, I dug a little deeper and found Solyn. Needless to say, their pricing is great compared to some of the “boutique” suppliers out there, and their service is great. Orders always ship fast, and email response to my dumb questions are unexpectedly fast as well. As long as they are in business, I’ll be a customer!

I am leaving a review again since the last one that I have done it was taken down. I bought 4 tesamorelin peptides and the quality of the product it’s horrible. I have been doing peptides for years and I have tried different labs and nothing it’s like this one. As soon as I constituted the peptide it got with a very weird texture and I had to trash out all 4 of them. This was a waste of money and I do not recommend this lab. I don’t want to receive calls or emails from you here is the why and how this happened. If you delete my review again I will write it again and again becuase this lab is NOT good at all.

Hi Favianna, we take feedback like this seriously, so we dug into this and got it resolved — your refund has been processed. Every batch we sell is independently tested, and the COAs are publicly verifiable directly on Vanguard Laboratory's website. We're always working to earn that kind of trust, and we appreciate the chance to make this right and to that end we hope you enjoy the additional items we sent at no additional charge to you.

A professional friend of mine in NC USA recommended I take these to heal my body. I am a mere mortal average man as many of you may be, I feel 10 years younger, grew up at the bottom of the poverty line eating toxins from the microwave. I owe these guys a big thanks! Thank you for everything SOLYN.

I've been really happy with this peptide site. The quality has been consistent and they were super easy to incorporate into my routine. Shipping was fast, everything arrived well packaged, and I'll definitely be ordering again. Highly recommend!!
