My attempt at decreasing my shortness is coming along slowly but surely. Previous results are here: Bone Length Increase. Lots of people have reported small incremental gains(including myself) and then the gains taper off. I think that might be due to telomere shortening. LSJL upregulates genes in the TGF Beta, ECM, PI3K, and Wnt pathways. The TGF-Beta pathway results in telomere shortening(TGF Beta isn't bad, I like to think of it as paying a toll, you get a cell division you have to pay with a telomere).
Astralagus(or possibly TA-65 as Astralagus may not have sufficient quantities of TAT2) may reverse telomere shortening. Post epiphyseal fusion, LSJL either works by new osteoblast bone deposition beneath the subchondral plate or by organic development of chondrocytes(all that's needed is Type I collagen & hydrostatic pressure which is generated by LSJL to cause differentation of mesenchymal stem cells into chondrocytes). Why I and others experienced rapid growth and then slowed(many have reported noticing growth of millimeters within the first week) is that the telomeres of the MSCs are too short to allow for further cell division.
Pre-fusion you not only want to simulate telomeres but you want to stimulate DNA Methylation, cGMP, IGF-1, Testosterone, etc. Of course, telomerase can be stimulated by things like aerobic exercise as well which explains why height gains have slowed but not ceased as the body might need time to replenish.
Right now I'm doing 30 seconds clamp, 30 seconds 75 lbs dumbell, and 30 taps with 10 lbs dumbell. I'm pretty consistently 5'9 1/2" which is up from my initial 5'8 1/2" but no big height gains lately.
