I like everything
I like everything - except the labeling is hard to read with all the dark colors and small lettering. I am not a fan of the labeling. The MG and the name of the peptide should be easier to see. Also should have a partner program.

Little hiccups, overall a great source of research grade peptides!
This company is awesome! Had one time the wrong peptide was sent to me, which was quickly exchanged, and one occurrence of research peptide getting degraded during transport, (it was during a week of>100 degrees F while it was transported) which was promptly replaced. Other than that the other 10+ orders have been accurate, pure, correct dosage, and quick to be shipped and received. Highly recommend this company due to the cheaper than average prices, and the excellent customer service.

Just ordered a vial of 10mg Reta from…
Just ordered a vial of 10mg Reta from them for the first time. I have ordered from many different vendors previously and had one I thought was solid but the quality has fallen off recently. Hoping this company has quick shipping and good products so I can make them my new main source. Will update when the package arrives.

Fast service helping with my problem
I had originally posted that I was having difficulty getting my package shipped and communication. They got back to me within an hour and had all of the tracking information and knew exactly where it was and when it was shipped and packaged right down to the minute. Apparently, in an email that I received to show me how to track it. It must’ve been sent by a different carrier so that was discrepancy, but they stepped right up and helped smooth everything over and I look forward to my packages writing soon.
