jakexb, It’s entirely possible that I’ve misunderstood something, but I believe Bucky Labs has had Klotho peptide available for quite some time. However, Bucky Labs sells in in micrograms, not milligrams. I believe other peptide sellers have also had it available. But, feel free to correct me if I’m off-base on this.
Interestingly the dose they suggest is 500mcg per day, which is orders of magnitude higher than what is suggested by the biohackers that have used the bucky lab source. I forget what the equivalent dose is to rats/monkeys, but the dose they recommend is definitely more in the ballpark of human equivalent. The other threads on klotho in this forum go into more detail on the skepticism around current biohackers likely homeopathic dosing (at the instruction of Steve Perry)
