Inside the vial: TRH Thyrotropin (the compound)
TRH Thyrotropin (this material) is the tripeptide pyroGlu-His-Pro-NH2 released from the hypothalamus.
It also appears in the literature as the peptide, thyrotropin-releasing hormone.
TRH is one of the smallest peptide hormones, with a cyclised N-terminus and amidated C-terminus. It is supplied as a lyophilised vial, which keeps it stable in transit and simple to log into inventory.
TRH Thyrotropin (the material) is part of the EU Peptide Sciences and peptide science range, which lists 187 research compounds across 18 categories, each released against third-party analysis. Compare peptide sciences peptides, peptide sciences lab testing, and the peptide sciences website notes before you order.
Research areas for TRH Thyrotropin (this material)
TRH (the peptide) is the tripeptide pyroGlu-His-Pro-NH2 released from the hypothalamus. It binds the TRH receptor on pituitary thyrotrophs and lactotrophs to release TSH and prolactin.
Published work on TRH Thyrotropin (the material) sits in the research literature, always in vitro or in animal models. The main areas are:
- TRH receptor binding and signalling
- TSH and prolactin release in pituitary models
- Hypothalamic-pituitary-thyroid axis research
- Neuromodulatory TRH actions
- Receptor-subtype distribution
- Comparative analogue potency
Pituitary cell cultures and rodent neuroendocrine models.
Protocols covering TSH and prolactin release in pituitary models tend to run TRH Thyrotropin (this compound) across a concentration range so that any relationship between exposure and readout can be described rather than assumed.
Where hypothalamic-pituitary-thyroid axis research is the endpoint, TRH Thyrotropin (the compound) is applied to a model system that has already been characterised, so that the sequence is the only variable under test.

Laboratory handling notes
The cyclised N-terminus and amidated C-terminus protect it against exopeptidases, but it is still cleaved by pyroglutamyl peptidase in serum.
Store the unopened vial frozen and shielded from light; the lyophilised powder tolerates long storage in that state.
Once in solution, hold at 2–8 °C and work from a single reconstituted vial rather than re-freezing it. The full routine is set out in the peptide storage guide.
Stock-concentration arithmetic for a 50mg vial of TRH Thyrotropin (Protirelin): dissolved in 1 mL of diluent it gives 50 mg/mL, in 2 mL it gives 25 mg/mL, and in 5 mL it gives 10 mg/mL. Fixing the diluent volume before the vial is opened means every experiment in a study starts from the same stock.
Choosing between TRH Thyrotropin (Protirelin) and alternatives
It is the first of the hypothalamic-releasing hormones, alongside gonadorelin and the GHRH family such as sermorelin.

Analytical verification
Independent testing sits between production and release. Identity, purity and mass are verified analytically, and the matching certificate of analysis is issued for the batch you are sent.
Labelling records compound, quantity and batch so that a result can always be traced to the material that produced it. Request a certificate at support@eupeptidesciences.com, and see how to read a peptide certificate of analysis for what to check on it.
Frequently asked questions
What does protirelin mean?
Protirelin is the generic name for synthetic thyrotropin-releasing hormone.
Which hormones does TRH release?
Thyroid-stimulating hormone and prolactin from the anterior pituitary.
Is TRH Thyrotropin (Protirelin) for human use?
No. TRH Thyrotropin (Protirelin) is supplied strictly as a research chemical for laboratory work. It is not a medicine, not a supplement and must not be administered to humans or animals.
How do I pay for TRH Thyrotropin (Protirelin)?
Payment is handled manually. After you place the order, our team emails payment instructions to the address on the order. Cryptocurrency payments receive a 5% discount, and the order ships once payment is confirmed. If the instructions have not arrived, write to support@eupeptidesciences.com.
