Peptide regulators: FDA, MHRA, and TGA
Regulations differ by country. PepExact does not answer legality questions — here are the primary authorities for the United States, United Kingdom, and Australia.
What PepExact is — and isn't
PepExact is an educational measurement tool. It takes numbers you already have — a vial size, the water added, a dose — and returns the units on a syringe, with the arithmetic shown. That is the whole product.
It does not sell peptides, link to vendors, recommend doses, or advise on obtaining or importing anything. And it does not provide legal advice. Nothing on this page is legal advice.
Why there is no single yes or no
“Peptides” covers many substances and forms. Whether a specific one may be possessed, imported, or supplied — and under what conditions — depends on that substance, its presentation, and how the law treats it where you are. Those are questions for the regulator and the law, not for a calculator.
Where the authoritative answers live
- United States — FDA. The Food and Drug Administration regulates medicines and related products in the US.
- United Kingdom — MHRA. The Medicines and Healthcare products Regulatory Agency is the UK medicines regulator.
- Australia — TGA. The Therapeutic Goods Administration regulates therapeutic goods in Australia. For AU-focused framing, see Are peptides legal in Australia?.
Common questions
Can PepExact tell me whether a peptide is legal where I live?
No. PepExact is a measurement calculator. It converts a vial, water, and a dose into syringe units and nothing else. It has no information about the legal status of any substance and does not provide legal advice.
Which regulator should I check in the US, UK, or Australia?
United States: the Food and Drug Administration (FDA). United Kingdom: the Medicines and Healthcare products Regulatory Agency (MHRA). Australia: the Therapeutic Goods Administration (TGA). Status depends on the exact substance and form — only the relevant regulator is the source of record.
Does PepExact sell peptides or help obtain them?
No. PepExact sells nothing, links to no vendors, and offers no guidance on obtaining, importing, or sourcing any substance.
