What Is PeptideX

PeptideX is an education site. It indexes 94 bioactive peptides with an evidence tier and an FDA status that cites a primary source, written so a reader can see what is known and what is not approved.

// THE PROBLEM

Peptide research is fragmented and hard to navigate

There are thousands of published papers on bioactive peptides — spread across PubMed, ClinicalTrials.gov, preprint servers, and proprietary databases. Evidence quality varies wildly. Regulatory status changes frequently. Community knowledge lives in forums.

Basic facts are scattered: Is there a human trial? What did FDA actually say about this substance, salt, or route? Which drug product, if any, is approved?

// THE SOLUTION

94 compounds indexed with structured, machine-readable profiles

Evidence scored by tier: Human RCT → Animal Only → Theoretical

Source-linked regulatory context for FDA 503A/503B substance contexts

Primary-source links for FDA status, trials, and public prices

// 01 — EVIDENCE METHODOLOGY

How We Score Evidence

5/5
Multiple Human RCTs

Multiple randomized controlled trials in humans with consistent findings

4/5
Single Human RCT

At least one randomized controlled trial with human subjects

3/5
Animal + Strong Mechanistic

Robust animal data plus well-characterized mechanistic pathway

2/5
Animal Only

Evidence limited to preclinical animal studies only

1/5
Theoretical

Mechanism proposed but no controlled experimental validation

Regulatory Classification Framework
Nomination withdrawn

Previously in Category 2; FDA still identifies potential significant safety risks. Withdrawal does not establish approval, safety or compounding eligibility.

Route-dependent status

GHK-Cu: injectable nomination withdrawn; non-injectable 503A Category 1 under evaluation. Neither is approval.

Framework-specific category

503A and 503B classifications differ; Category 2 identifies safety risks and Category 3 indicates inadequate nomination information.

Status not verified

Exact identity or product-specific FDA approval is unsupported. No approval or eligibility inference.
