The Book of PeptidesThe Book of Peptidessoluble alpha-Klotho
The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. None of the compounds covered are approved for the uses described here by the U.S. FDA, Australia's Therapeutic Goods Administration (TGA), New Zealand's Medsafe, or the equivalent regulator in most other countries.
Most are sold for laboratory research only, a few are prescription-only drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful wherever you live. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.
Cross-checked against 50–100 independent sources per claim — the house standard. How this reference is checked
Reference values as published in the research record — not a recommendation, instruction, or dose suggestion for any person. Not medical advice.
No established human dose — this compound doesn't have a settled protocol yet.
Not reconstituted — vials delivery, so there's no vial to draw from.
Klotho is not a peptide but a ~130 kDa glycoprotein, made in cell culture, not by peptide synthesis, and dependent on correct glycosylation. The best evidence is preclinical: Castner and colleagues (Nature Aging, 2023) gave 18 aged rhesus macaques one subcutaneous injection; 10 mcg/kg improved working memory within hours and still at two weeks, while 30 mcg/kg did nothing.
The member edition is the full write-up: every claim cross-checked against independent sources and challenged before print. What didn't survive the check isn't in here.
The full published spec sheet — dose units, timing, frequency, and cycle length — is included with membership.
