Research Compounds vs Approved Medicines
A plain-English guide to the difference between research compounds, clinical trial medicines, prescription medicines, compounded medicines and unapproved therapeutic goods in Australia.
Quick summary
The terms used online can be confusing. “Research compound”, “research use only”, “clinical trial medicine”, “prescription medicine” and “unapproved therapeutic good” do not mean the same thing.
Research compound
A substance may be studied in laboratory or scientific contexts. This does not mean it is approved, safe, lawful for supply, or suitable for human use.
Clinical trial medicine
A product may be investigated in humans under controlled clinical trial conditions, with ethics, protocol and regulatory requirements.
Approved medicine
An approved medicine is included in the Australian Register of Therapeutic Goods for lawful supply in Australia, subject to its approved conditions.
Why the difference matters
In Australia, therapeutic goods are regulated because they can affect health, disease, injury or physiological processes. A product’s legal position may depend on its ingredients, intended use, claims, supply method, prescription status and ARTG status.
Simple rule
A product being discussed in research does not mean it is approved as a medicine. A product being sold online does not mean it is lawful, safe, sterile, effective or appropriate for human use.
Comparison table
This table explains the key differences in simple terms.
| Category | What it means | Important limitation |
|---|---|---|
| Research compound | A substance discussed or studied in scientific, laboratory or experimental contexts. | Research interest does not prove safety, effectiveness, legality or suitability for human use. |
| Research use only | A label or statement often used to indicate that a product is not intended for human therapeutic use. | The wording does not automatically make supply lawful and does not prove quality, sterility or regulatory compliance. |
| Clinical trial medicine | A product investigated in humans under a clinical trial framework, often with ethics approval and trial protocols. | Being in trials does not mean the product is approved for general public use. |
| Prescription medicine | A medicine that generally requires assessment and prescription by an authorised health professional. | Prescription-only medicines are generally not permitted to be advertised to the public. |
| Approved medicine | A medicine included in the ARTG for lawful supply in Australia, subject to approved conditions. | Approval is product-specific. It does not automatically apply to similar compounds, imported versions, research products or copies. |
| Unapproved therapeutic good | A therapeutic good that is not included in the ARTG. | The TGA says these goods have not been assessed for safety, quality or effectiveness. |
| Compounded medicine | A medicine prepared for a particular patient in specific circumstances by an authorised practitioner or pharmacy. | Compounded medicines may still be subject to advertising restrictions and are not the same as ordinary retail products. |
What is the ARTG?
The Australian Register of Therapeutic Goods is the public database of therapeutic goods that can be legally supplied in Australia. It can include product, sponsor and manufacturer information.
Included in the ARTG
The product has been included for supply in Australia, subject to its category, conditions and approved use.
Not included in the ARTG
The product may be an unapproved therapeutic good. Access may only be possible under specific pathways where strict conditions are met.
Unapproved therapeutic goods
The TGA describes unapproved therapeutic goods as products not included in the ARTG. This means they have not been assessed by the TGA for safety, quality or effectiveness.
Not assessed
Unapproved does not mean TGA-tested, TGA-endorsed or clinically accepted for general use.
Specific pathways
Access pathways may exist in limited circumstances, such as clinical trials, authorised prescriber arrangements, special access pathways or personal importation conditions.
Not a shortcut
Access pathways do not mean a product can be promoted, advertised, resold or supplied freely to the public.
Prescription medicines
Prescription medicines require professional health assessment. The TGA notes that advertising prescription-only medicines to the public is generally prohibited because it can encourage inappropriate self-diagnosis and undermine the role of health professionals.
Health professional assessment
A doctor or authorised health professional considers the patient, condition, risks, medicines, contraindications and monitoring needs.
Public advertising restriction
Prescription-only medicines and unapproved therapeutic goods are generally not permitted to be advertised to the public.
Clinical trials are different
A medicine being investigated in clinical trials is not the same as being approved for public supply. Clinical trials operate under structured research protocols and regulatory requirements.
Controlled setting
Clinical trials usually involve defined eligibility criteria, monitoring, ethics oversight and reporting requirements.
Research question
The purpose is to study safety, dosing, effectiveness or other scientific questions under controlled conditions.
Not public approval
A compound being in trials does not mean online products are approved, lawful, equivalent or safe.
Common misconceptions
These are common misunderstandings seen in online peptide discussions.
“It says research use only, so it must be fine.”
No. A label does not prove lawful supply, quality, identity, purity, sterility, safety or suitability for human use.
“It has a COA, so it is approved.”
No. A laboratory report is not the same as ARTG inclusion, TGA approval, GMP manufacture or medical supervision.
“It is in studies, so it is safe.”
No. Research may identify possible risks, uncertainties or reasons a compound should not be used outside controlled settings.
“A similar medicine is approved, so this version is approved.”
No. Approval is product-specific. Similar compounds, copies, overseas products or research-grade products may have different legal and safety status.
What this means for readers
This website is designed to help readers understand regulatory concepts, not to encourage use or provide treatment guidance.
Use official sources
- Check the TGA website.
- Search the ARTG where relevant.
- Understand whether a product is prescription-only.
- Read official warnings and safety alerts.
- Speak with a qualified Australian health professional.
Avoid assuming
- Do not assume online supply is lawful.
- Do not assume “research use only” means safe.
- Do not assume overseas products meet Australian standards.
- Do not assume a COA proves clinical safety.
- Do not use online claims as medical advice.
