A letter for each compound × outcome, drawn from randomised trials and meta-analyses — with effect size and every caveat spoken plainly. The preclinical never poses as proven.
How we grade →There is no production yet, so there are no batch assays to show. When there is, this is the commitment: independent testing, each result verifiable by its task number, and a blind retest on request. Until then this block describes an intention, not a practice.
Reading a COA →One person writes these grades: Yakiv Bilenko, who also runs Vallydia and sells its serums. There is no independent reviewer, and none is promised. What can be checked instead is the record: our own copper peptide is graded B, the competing peptides B, B and C. We do not grade upward what we profit to sell.
For compounds eligible through a licensed pharmacy, we point you to legitimate access as information — never a grey checkout. Dosing is a clinician's call, never a product page.
The reference does not sell. The shop does not grade. Keeping the two apart is what lets either be trusted.
A compound's grade is written from the published evidence, by the same method whether or not we sell the thing — and the register shows our own ingredient graded no more kindly than its competitors. Whether we can offer it to you is a separate, lawful-lane decision made per region — a cosmetic carries a price; a research compound carries only a follow.
No dosing, reconstitution, or administration guidance is published for research compounds anywhere on this site. That restraint is deliberate.
Yakiv Bilenko writes the evidence grades and runs Vallydia. There is no editorial board and no panel — one person, working from published trials, meta-analyses and regulatory texts, by the method set out here.
There is no independent clinical reviewer, and none is promised. What the method offers instead is that the reasoning behind each grade is written out and its sources listed, so you can check the argument rather than take a credential on trust.
The interest, stated plainly: Vallydia sells its own cosmetic serums, and some graded ingredients compete with them. Vallydia is self-funded; it takes no supplier or brand money, and no ingredient maker has paid for, reviewed, or seen a grade before publication. The claim worth checking rather than believing is the register itself — our copper peptide is graded B, while the competing peptides are graded B, B and C.
A neutral reference and a lawful-lane shop. Information for those who seek it — never promotion.
