Retatrutide45–541–3 monthspositiveStill usingObservation date: 2026-09

I started Retatrutide at a very low dose to see if it would help me loss some weight. I found that it worked immediately and am happy to say that I have lost 7 pounds so far. I also take GHK-CU for hair and skin benefits. So far I have noticed that my nails grow faster and my hair seems to be growing with a little more thickness.

I had a lot of pain in my GI tract and needed something to help overcome it and was introduced to BPC-157 by my son. It immediately helped with the pain and over a few weeks the inflammation was nearly gone. It helped the doctor and I focus on the true issue, which is possibly fatty liver.

It has been unbelievable, I never thought that the results would happen so fast. I lost 20 pounds with some adjustments to diet and exercise. I also sleep a little better at night which is what I was told is a key part of this peptides ability to work.

I was told that this medication could help for many of my old military injuries and after being on it for a while it has made a big difference. I can do more things with less pain, such as lifting weights or simply climbing stairs at my house. It just feels so much better to get up in the morning.
