Hi!
Have you considered posting in the Weight Loss section of the forum with your current daily caloric intake, exercise routine, and current stack (supplements, peptides, etc.) and requesting advice? I'd start there.
Also, how much weight have you lost so far? My weightloss flat-lined for a couple months when I was about 50 pounds down. I'd lost weight until I hit one of my body's set points, or weight that I had previously been stable at for an extended period of time. This is a known phenomena that happens. Your body might also just need a break from losing. It's stressful to continuously and/or quickly drop pounds, as it makes your survival instincts kick in, and they can override your weight loss efforts. I'm now down almost 90 pounds, and floating around a weight that is comfortable for me, aside from the loss of cushion for my tailbone and hips - ouch! It took patience and discipline to get here.
Then, after you have really looked at your diet and movement, consider your peptide dose, assuming you're already on one. Is it time to move up a bit? Or, even try a different vendor. That seemed to help me, as non-sensical as it may seem. However, I mostly attribute that to the new vendor being known for well over-filled vials, and my dose being subsequently higher due to me choosing not to strictly account for that in my reconstitution math.
The product that you are asking about does not currently have studies based on human consumption. That doesn't mean it's definitely harmful; however, it does mean that we really don't know a whole lot about it. I do see that one side effect can be insulin resistance. It's also stated that it has a lowered chance of increasing the growth rate of tumors, but that chance is still non-zero. If you have a personal history of cancer, I'd stay away from any HGH types.
Personally, I prefer to stick to peptides and other items that are more studied; however, everyone has different risk tolerance levels. Only you can decide if Frag 176-191 is a risk you're willing to take.
Weight loss is non-linear, and it is best to go slow and listen to your body. A stall could be just what your body needs to regroup and de-stress after losing a large percentage of body weight. Slow and steady is best. Fat burners are typically not as great as vendors make them out to be. There is no 'magic pill/injection.' The closest to a magic fix that I've had experience with is tirzepatide, but I still had to do the work - managing my diet and activity levels over an extended period of time- to see results. Consistency is important, but sometimes your body needs a break. A short-term increase in calories may be beneficial if you have been heavily restricting.
Feel free to share more details of your journey thus far. It's difficult to point someone in a direction if you don't know where they've already been.
