Evidence for hormone balance

Each row is an outcome related to hormone balance from a published study, strongest design first. Animal and cell results are labelled and are not human results. User reports are not counted as evidence here.

How strong is it?

Strongest evidence:Human RCT evidence, 4 of 4The Journal of clinical endocrinology and metabolism 1992, PMID 1379256

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.

Hormones in plain terms

MedlinePlus calls hormones the body's chemical messengers that travel in the bloodstream to tissues or organs.[4]

The hormones sermorelin studies measured

Sermorelin is a GHRH analogue, so the hormones measured were growth hormone and IGF-I; GHRH injections restored both towards young-adult levels in old men.[1]

In hypogonadal men on testosterone therapy, the combination that included sermorelin was followed by higher IGF-1, with smaller rises in men also taking an aromatase inhibitor or tamoxifen.[2]

In the children's trial, no adverse changes in general biochemical or hormonal analyses were noted during a year of daily sermorelin.[5]

The goal ledger's PubMed count for sermorelin with hormone-balance terms (a broad estrogen, progesterone and hormone-balance query) was 2 records tagged human and 0 tagged animal-only; the ledger flags the term as ambiguous.

Common questions

Does Sermorelin help with hormone balance?

The strongest study we summarise for hormone balance is human rct evidence, across 3 studies with an outcome for hormone balance. A trial result is not an approval; see the legal status.

Is Sermorelin approved for hormone balance?

No. Sermorelin is not FDA approved for any use, including hormone balance.

What is the best peptide for hormone balance?

There is no single answer. Our hormone balance overview compares each candidate by evidence grade and legal status rather than by popularity.

Does sermorelin balance hormones?

In healthy old men, short-term GHRH injections reversed age-related falls in GH and IGF-I; no cited study shows it balancing oestrogen, progesterone or testosterone.[1]
