After dropping 79kg I'm left with a great deal of sagging skin, so clearly the reason must be that I never took Glow as a preventive measure. (Honestly, I'm glad to be dealing with this particular issue.)
From everything I've come across or grasp about human physiology, a peptide simply isn't capable of changing this. The bands of elastin and collagen fibrous tissue running through the subcutaneous fat, which anchor skin to the tissues beneath, have been stretched out over a long period. Any of them still holding tension will contract in size after weight comes off, but once they've lengthened I simply can't accept that they'll remodel. It's not impossible that localized treatments might do something, yet achieving uniform results with them would likely be unachievable.
If peptides were driving connective tissue growth on that scale (throughout the entire body beneath the skin, and enough to firm up sagging skin), I'd be deeply concerned about them spurring fibrous tissue growth in other places too, such as the heart, lungs or kidneys, leading to severe organ dysfunction.
Naturally, absent an enormous clinical trial there's no way to ever know whether it worked. If you reach the end without loose skin, it will appear as though it worked. I'd be genuinely astonished if you could placebo-effect your way into subcutaneous tissue remodeling.
