An analogue of growth hormone-releasing hormone — the signal the hypothalamus sends the pituitary. It acts upstream of growth hormone rather than supplying it.

Is sermorelin the same as HGH?

No. Somatropin supplies growth hormone directly; sermorelin acts on the gland that produces it. They are regulated and used differently.

Is sermorelin FDA-approved?

It held US approval historically and was withdrawn as a marketed branded product. It is now supplied as a compounded preparation on a prescriber's order.

Why was it withdrawn?

It was discontinued as a branded product. That is a commercial and regulatory event rather than a safety determination in itself.

Sermorelin

Sermorelin is an analogue of growth hormone-releasing hormone — specifically the active fragment of the signal your hypothalamus sends your pituitary. It is not growth hormone. It is a signal that acts upstream of it.

It has an unusual history for this category: it was once an approved medicine in the United States, was withdrawn as a branded product, and now reaches patients through compounding pharmacies.

What sermorelin is

Growth hormone-releasing hormone is the signal the hypothalamus uses to tell the pituitary to release growth hormone. Sermorelin corresponds to the active portion of that signal.

The distinction from growth hormone itself is genuine and frequently blurred in marketing. Somatropin supplies the hormone directly. A GHRH analogue works upstream, acting on the gland that produces it — which is why the two are regulated and discussed differently.

Approved, then withdrawn

Sermorelin held US approval historically and was discontinued as a marketed branded product. Withdrawal of a brand is a commercial and regulatory event; it is not, by itself, a safety finding, and it should not be read as one in either direction.

What it does mean practically is that anyone receiving sermorelin today is receiving a compounded preparation. The oversight, the evidence base and the supply chain all look different from a branded approved medicine, and you should understand how before agreeing to anything.

Where it stands now

Sermorelin is prescribed by clinicians working in this area and prepared by compounding pharmacies on their order. That is a lawful route with real oversight attached, and it is materially different from buying research-chemical material online.

It is prohibited in competitive sport under WADA's rules covering peptide hormones and growth factors.

What being a compounded product changes

Compounding is a long-established and lawful part of pharmacy, but it is regulated differently from drug manufacturing, and the differences are worth knowing rather than glossing.

There is no approved label, so there is no regulator-reviewed account of adverse effects to consult.
Preparations are made for an individual patient rather than produced to a single standardised specification.
Quality depends heavily on the specific pharmacy, which is why asking which one is a reasonable question.
Insurance coverage is uncommon, so this is usually a cash cost.
Availability can change if the regulatory position on a substance shifts.

None of that makes a compounded preparation inherently unsafe. It does mean the assurances you would get automatically with a branded medicine have to be asked for here instead.

What a proper conversation looks like

A clinician working responsibly here will want to know what symptom or finding prompted the question, will measure before prescribing, and will be specific about which pharmacy prepares the preparation. Growth hormone signalling can be assessed with laboratory work, and it should be.

Expect the possibility that the answer is no. Fatigue, poor sleep, low mood and changes in body composition all have far more common explanations than growth hormone signalling, and a clinician who investigates those first is doing the job properly rather than obstructing you.

Talk to a licensed provider before considering any of this

Peptides are prescriber territory, and the useful first step is finding out what is actually going on rather than picking a compound. We connect you with licensed providers who investigate first.
