Insufficient Evidence
7 dimensions · 100 points total · Methodology by PeptideClear
Scoping Note
This score reflects evidence specific to Pentadeca Arginate (PDA) as a distinct compound. BPC-157 animal research is not applied here — PDA is a structurally related but separate peptide with its own (largely absent) evidence base. Extrapolating BPC-157 findings to PDA is not scientifically supported.
Dimension Breakdown
DimensionScoring NotesScore
Study Design
No published human trials. A small number of animal studies exist in rodent models examining tissue repair and anti-inflammatory effects, representing the extent of the published evidence base. Animal only score applies. The absence of a human safety study — let alone an efficacy trial — is the defining limitation.
5 / 25
Sample Size
No human participants. Animal study cohorts are small (typically 8–16 animals per group). Score is 0 for this dimension as no human efficacy data exists.
0 / 20
Replication
The limited animal studies that exist originate from a small number of groups, with no meaningful independent replication. Single study or single group at best. Score reflects the near-complete absence of a replication record.
5 / 20
Journal Impact Factor
The sparse published work appears in lower-tier journals or preprint form. No publications in peer-reviewed journals with meaningful impact factors have been identified for PDA-specific research.
4 / 15
Funding Independence
The available animal research does not appear to trace primarily to vendor or commercial interests — but the overall data volume is too thin to assess this dimension meaningfully. Score reflects the limited evidence available, not confirmed independence.
4 / 10
Population Diversity
Animal only — not applicable to human population diversity scoring.
0 / 5
Researcher h-Index
No prominent lead researcher with an established publication record specific to PDA has been identified. The compound is too new and too thinly researched to have a named academic investigator. Score is 1.
