My spreadsheet can't separate peptide hype from the GLP-1 slope

I keep getting pulled into IGF-1 LR3 vs HGH threads because the arguments sound tidy, but my own data is messier. I'm 14 months on a GLP-1, down 81.4 lb from my highest logged morning. My last 19 weekly averages give a slope of -0.36 lb/week, and waist is down 4.25 inches since February. Protein is 135-150 g, steps average 8,100, two full-body sessions. The contrarian part of me says: if I add another variable now, I can't credit it. The spreadsheet would just have a new column and worse attribution. I'm not anti-peptide; I'm anti-uninterpretable data. Has anyone actually tracked IGF-1 LR3 or HGH alongside GLP-1 stuff and seen a change that wasn't explainable by appetite, training, or sleep? Or is it mostly forum noise?
