Most peptide numbers online have no source. We publish the source.
Vialog is an evidence ledger for research compounds. Every figure on this site carries the species it came from, the route it was given by, the sample size, and a link to the paper. Where a widely repeated claim traces back to nothing, we publish that too — marked as what it is.
Compound records
All 99 →The grade describes the strongest evidence that exists for the compound — not whether it works, and not whether anyone should use it. Most of this category rests on animal data.
| Compound | Strongest evidence |
|---|---|
| 5-Amino-1MQ5-Amino-1MQ: verified identity, the rodent NNMT record with species, route and sample… | Animal onlyMouse, rat and cell-culture work only; zero registered human trials, and the two published oral bioavailability figures disagree elevenfold |
| 9-Me-BC (9-methyl-beta-carboline)9-Me-BC: identity verified against PubChem and FDA GSRS, the 1998 mouse study that… | Animal onlyRodent and cell-culture work only; no registered human trial and no published human data of any kind |
| ACE-031 (Ramatercept)Verified identity for ACE-031 (ramatercept), its four registered trials, the registry's… | Human dataTwo published randomised human trials totalling 72 participants; development discontinued in 2013 and the molecule is approved nowhere |
| ACE-083 (Efmitermant Alfa)Verified identity for ACE-083 (efmitermant alfa), its four registered trials with… | Human dataThree published human trials totalling 216 participants, across a four-study programme of 278 registered enrolments; development ended in 2020 and the molecule is approved nowhere |
| AHK-CuAHK-Cu has one indexed primary study and one granted patent. Every figure carries… | Animal onlyRodent hair-growth data exist only in four worked examples of a granted patent, not in peer-reviewed literature; the indexed record is one 2007 ex vivo and cell-culture paper; zero registered human trials |
| AICAR (Acadesine)Verified identity for AICAR (acadesine), the 4,043-patient CABG meta-analysis, the… | Human dataLarge randomised human trials exist, all intravenous and all in cardiac surgery, with smaller intravenous studies in haematology and type 2 diabetes and oral dosing confined to pharmacokinetic and anti-doping elimination work; not an approved medicine in any jurisdiction, prohibited in sport at all times, and no human study of exercise capacity has ever been registered or published |
| AOD-9604 (LAT-8881)Verified identity for AOD-9604, the 502-patient obesity trial that failed, and three… | Human dataRandomised placebo-controlled human trials with posted results; the four efficacy endpoints tested were not met; not an approved medicine |
| ARA-290 (Cibinetide)ARA-290 (cibinetide): verified identity, every human trial figure with population and… | Human dataFour small randomised trials in patients plus one in healthy volunteers, largest 64 subjects, none longer than 12 weeks; not an approved medicine in any jurisdiction |
| ATX-304 (O-304)ATX-304 (O-304) evidence ledger: verified identity, the single published human trial… | Human dataOne published 28-day phase IIa trial (n=65); all other findings are rodent or in vitro |
| AdamaxAdamax has no published study of any kind: PubMed returns only machine-learning papers.… | No source foundNo primary literature on this molecule in any species or assay; every figure on this page was measured on the unmodified parent peptide or on unrelated adamantylated peptides |
| Albuterol (Salbutamol)Verified identity for albuterol (salbutamol) plus every trial figure logged with… | Human dataRandomised human trials across four decades, from 1992 to 2026, including an eleven-week resistance-training trial; an approved bronchodilator, with no indication in current FDA labelling relating to muscle mass, fat mass or body composition, and no non-US register searched for this page |
| Aminotadalafil: An Evidence LedgerAminotadalafil, the tadalafil analogue found in adulterated supplements. What the… | In vitroAnalytical detection and structure-elucidation studies, plus one in vitro screen in which the compound was inactive; no pharmacology, no animal work, no human administration |

What we are actually useful for
There are roughly thirty peptide information sites. Nearly all of them publish a dosing table, a benefits list, and a vendor ranking. We publish none of those three, deliberately — the first two are medical advice we are not qualified to give, and the third is an advertisement wearing a lab coat.
Tracing numbers back to their source
A widely repeated line holds that GHK regulates at least 4,000 human genes. It appears in the abstract and introduction of a 2015 review, uncited. The primary gene-expression work that the same review goes on to describe reports 127 genes, across 64 tissue samples. The figure travels; the context does not. Every claim here is logged with species, route, sample size and citation — or marked No source found with a note on what we searched.
Reading a certificate of analysis
A COA showing 99% purity by HPLC tells you what fraction of the peptide content is the intended peptide. It tells you nothing about how much peptide is in the vial — that is a separate quantitative assay most certificates omit. Purity is routinely read as a guarantee of content. It is not one.
