Tesamorelin vs HGH and IGF-1 LR3: Three Levels of the Axis
Tesamorelin stimulates the pituitary, HGH is the hormone itself, IGF-1 LR3 acts downstream. How the three differ in feedback, size and research use.

Comparisons
Sermorelin acts at the top of the GH-IGF axis; IGF-1 LR3 is a modified version of the axis output. A comparison of upstream and downstream tools.
Research Reviews
IGF-1 LR3's persistence comes from evading binding proteins, not from intrinsic stability. What the clearance literature shows and what grade labels mean.
Lab Handling
IGF-1 LR3 is an 83-residue folded protein with three disulfide bridges. Why peptide reconstitution practice does not transfer, and what does.
Comparisons
IGF-1 DES and LR3 both alter the N-terminus to reduce binding protein capture, but by opposite means: one removes residues, one adds them.
Peptide Profiles
IGF-1 LR3 is a recombinant IGF-1 analogue with an N-terminal extension and an Arg3 substitution that reduces binding-protein affinity. What that changes.
