Welcome! I have been following the work of Dr Bill Andrews closely, but for the last year or so I haven't heard much from Sierra Sciences. Have you communicated much with Bill? He is a fascinating character in this field. It sounds like he was beginning to hit a ceiling with his telomere research and needed more funding.
Also, have you tried Epitalon, Cycloastragenol or Astragasolide IV? If so, what do you make of these?
I have tried GHRP-6 and it definitely improved my skin.
