Alpha-Lipoic Acid and GHRP-6: what the published research says

PubMed indexes 8 records that name Alpha-Lipoic Acid and GHRP-6 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Alpha-Lipoic Acid and GHRP-6. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Alpha-Lipoic Acid and GHRP-6.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Regulation of His-dTrp-Ala-Trp-dPhe-Lys-NH2 (GHRP-6)-induced GH secretion in the rat.

Neuroendocrinology · 1993 · PMID 8510800

Animal study

“On the other hand, chronic dexamethasone administration, acute elevation of circulating FFA levels and bombesin administration markedly inhibited GH responses to GHRP-6. In contrast to the effects exerted on GH responses to GHRP-6 estrogen administration led to a decrease in GH responses to GHRH while dexamethasone did not affect the GH responses to GHRH, highlighting a differential regulation of these hormones on somatotroph responsiveness to these peptides.”

Mallo et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Influence of endogenous cholinergic tone and alpha-adrenergic pathways on growth hormone responses to His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 in the dog.

The Journal of endocrinology · 1993 · PMID 8228729

Animal study

“Pretreatment with the cholinergic agonist pyridostigmine (30 mg per os) increased GHRP-6-stimulated GH secretion (37.9 +/- 10.1 micrograms/l P < 0.05), while the muscarinic blocker atropine (100 micrograms i.v.) completely abolished (GH peak lower than 2 micrograms/l) the stimulatory action of GHRP-6.”

Muruais et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Intranasal activity of the growth hormone releasing peptide His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 in conscious dogs.

Life sciences · 1991 · PMID 2046459

Animal study

“Based on these results, the intranasal activity of GHRP-6 should be evaluated in man. The successful intranasal administration of this peptide in man should provide GH therapy with reduced patient discomfort and better patient compliance when compared to presently available parenterally administered remedies.”

Nelson et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Oral activity of the growth hormone releasing peptide His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 in rats, dogs and monkeys.

Life sciences · 1990 · PMID 2117689

Animal study

“Although enteral activity is approximately 1% of parenteral activity, GHRP-6 is potent, especially in primates which require relatively low doses to provoke GH release. These data suggest that orally active GHRP-6 may provide a practical therapeutic alternative to parenterally administered peptides such as GHRH, especially if enteral activity is enhanced with appropriate formulation.”

Walker et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Effects of hypothyroidism, tri-iodothyronine and glucocorticoids on growth hormone responses to growth hormone-releasing hormone and His-D-Trp-Ala-Trp-D-Phe-Lys-NH2.

The Journal of endocrinology · 1989 · PMID 2497223

Animal study

“In-vitro studies carried out using monolayer cultures of rat anterior pituitary cells derived from euthyroid and hypothyroid rats showed a marked impairment of somatotroph responsiveness to both GHRP-6 and somatostatin in cultures derived from hypothyroid rats. In summary, our data suggest that thyroid hormones and glucocorticoids influence GH secretion by modulating somatotroph responsiveness to different GH secretagogues.”

Edwards et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Variables determining the growth hormone response of His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 in the rat.

Endocrinology · 1985 · PMID 4029086

Animal study

“Decreases in pituitary GH or increases in somatostatin secretion would not explain this decreased response because the GH response of MRZ 2549, an opiate agonist, was unchanged by GH-RP-6 pretreatment. In contrast to the acute effect of GH-RP-6, chronic daily injections of GH-RP-6 resulted in an enhancement of the GH-RP-6 response.”

Sartor et al. · From the abstract

Names both Alpha-Lipoic Acid and GHRP-6 in its title.

Pharmacokinetic study of Growth Hormone-Releasing Peptide 6 (GHRP-6) in nine male healthy volunteers.

European journal of pharmaceutical sciences : official journal of the European Federation for Pharmaceutical Sciences · 2013 · PMID 23099431

Clinical Trial, Phase I

“Dose dependence analysis revealed a noticeable trend for AUC to increase proportionally with administered dose. Atypical GHRP-6 concentration spikes were observed during the elimination phase in four out of the nine subjects studied.”

Cabrales et al. · From the abstract

Names Alpha-Lipoic Acid and GHRP-6 together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Alpha-Lipoic Acid, GHRP-6, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
