Peptides 101

A clean starting point for understanding the category.

Beginner-friendly education should lower confusion without flattening risk. This hub frames peptide categories, proof quality, and the questions buyers should ask before trusting a product.

Rule: evidence before hype

Category map

Peptide education for people who do not want to be sold to.

Each category can eventually become an SEO and education surface, but the first job is to teach evidence literacy.

Recovery and tissue

BPC-157

Tier Emerging

Often marketed around soft-tissue recovery and injury narratives.

TB-500 / Thymosin beta-4

Tier Emerging

Discussed around repair, mobility, and return-to-training stories.

Metabolic and body composition

Semaglutide

Tier A

Regulated metabolic therapy context exists, but gray-market product verification remains separate.

Performance and recovery

CJC-1295 / Ipamorelin

Tier C

Often positioned around recovery, sleep, body composition, and training support.

Evidence library

Sources are attached to product logic, not pasted in later.

The data model already separates compound summaries, source quality, side effects, and vendor proof.

COA

Lot-specific BPC-157 acetate COA

Tier B · 2025

Document lists purity, lot number, and assay method, but lab accreditation still needs confirmation.

Clinical guidance

Metabolic peptide clinical prescribing context

Tier A · 2025

Human clinical context exists for regulated metabolic therapies, but vendor claims still need product-level verification.

Review

Thymosin beta-4 tissue repair literature review

Tier Emerging · 2023

Mechanistic and preclinical discussion is stronger than direct product-level evidence.

Vendor document

CJC/Ipamorelin vendor batch packet

Tier C · 2025

Batch packet includes purity claims but lacks complete chain-of-custody and lab identity detail.

COA

Modern Aminos BPC-157/TB-500 5mg/5mg COA

Tier B · 2026

Public COA lists BPC-157 TB-500 5mg/5mg, lot BX-P-I9C1, LCMS/MS testing, average purity of 99.12%, and research-only language.

Compound detail

Each compound carries cautions, sources, and side-effect language.

This is the frontend shape a backend can eventually populate from a real evidence database.

BPC-157

Often marketed around soft-tissue recovery and injury narratives.

Injection-site irritation: Local irritation is commonly discussed for injectable products and should be monitored.

Medication interaction risk: Existing medications and conditions can change the risk profile and require professional review.

TB-500 / Thymosin beta-4

Discussed around repair, mobility, and return-to-training stories.

Medication interaction risk: Existing medications and conditions can change the risk profile and require professional review.

Semaglutide

Regulated metabolic therapy context exists, but gray-market product verification remains separate.

Source: Metabolic peptide clinical prescribing context

GI discomfort: Nausea, appetite changes, or GI disruption may appear in metabolic peptide contexts.

Medication interaction risk: Existing medications and conditions can change the risk profile and require professional review.

CJC-1295 / Ipamorelin

Often positioned around recovery, sleep, body composition, and training support.

Fluid retention: Some growth-hormone-adjacent discussions include swelling or water retention signals.

Injection-site irritation: Local irritation is commonly discussed for injectable products and should be monitored.

Medication interaction risk: Existing medications and conditions can change the risk profile and require professional review.

Proof checklist

Before the molecule, inspect the evidence.

The same checklist powers the checker, vendor scorecards, and future education pages.

1

What is the exact compound?

2

Is there a lot-specific COA?

3

Who performed the test?

4

How old is the document?

5

Do claims exceed the evidence?

6

What is missing?

Evidence tier

A readable label for how strong and current the proof appears to be.

Trust flag

A visible concern, such as old documentation or claims that outrun the COA.

Vendor scorecard

A broader view of transparency, support, QA posture, and market pattern.

Education becomes useful when it routes people into verification.
