I love KLOW/GLOW. Its great for inflammation, joints, muscle repair and overall skin health. However, it wont do anything for weight loss or retaining muscle. For retaining muscle, I would look into either cjc/ipamorelin, sermorelin or tesamorelin. You'll want to make sure you're doing some weight training in order to fully benefit from these though. Alternatively, you could always drop the tirz and transition to reta, since it has less muscle loss overall. If you're still waiting to lose more weight, you may also want to increase your tirz dose. 5mg is fairly low and a lot of people don't hit the "sweet spot" until they get to 7.5mg. Combining with cagri can help break a stall, but most people stack with cagri just to decrease the food noise further. Hope this helps!
