I don’t think Steve’s website is still maintained or responding to enquires.
From his cohort and peptides pioneers, there are still people taking GDF11 plus other peptides, but they are not actively engaging on websites, they prefers a low-profile approach while testing and advancing with the anti-aging exogenous peptides.
Regarding your question on dosing: yes that’s correct, we have learned that dosing on the femtograms per week range is still effective, and actually reducing/eliminating side-effects of prolonged (multi-years) exogenous administration.
Standard biomarkers are the ones identified by Steve, and they are still valid.
Just a hint: GDF11 is key peptide, but over the years I have identified other peptides, which taking together are significant countering the aging signs on individual, actually I might say one is effectively rejuvenating (e.g. stronger endurance, limited fatigue post heavy exercises, etc… and for men receding hair line reversals

Hope above will help.
