DSIP
Mechanism of action
What DSIP does in the body — step by step.
DSIP is a nonapeptide (sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) isolated in 1977 from the thalamic venous blood of rabbits.
Its molecular mechanisms of action remain incompletely understood.
Interactions with GABA receptors, a modulating effect on the hypothalamic-pituitary axis and neuroprotective properties via antioxidant pathways have been discussed.

Frequently asked questions
What is DSIP?+
DSIP is a nonapeptide (sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) isolated in 1977 from the thalamic venous blood of rabbits.
What type of peptide is DSIP?+
DSIP belongs to the Neuropeptide class.
What is DSIP used for?+
In research, DSIP has primarily been investigated in the context of: Cognition. These are research findings (evidence: preclinical), not proven benefits in humans and not a usage recommendation.
Is DSIP legal in Germany?+
The regulatory status of DSIP in Germany is not clearly classified.
Is DSIP FDA-approved / legal in the US?+
No. DSIP is not FDA-approved as a drug in the US; it is mostly sold as a research chemical and not for human consumption.
Is DSIP legal in Canada?+
No. DSIP is not authorized by Health Canada and not intended for human consumption.
Where can I buy DSIP?+
Peptica sells nothing and names no sources. DSIP is "unclassified" in Germany; obtaining unapproved substances outside clinical studies is illegal and carries quality and safety risks.
What is the dosage of DSIP?+
Peptica publishes no dosing. There are no approved dosing guidelines for DSIP; figures circulating online stem from animal studies or anecdote, not from validated human protocols. This is not medical advice.
Is DSIP banned in sport (WADA)?+
DSIP is currently not on the WADA Prohibited List.
What are the known risks of DSIP?+
Documented risks include: Lack of current safety data — long-term profile in humans unknown; Possible interactions with central nervous system pathways not sufficiently studied. This is not a complete safety assessment and not medical advice — see the risks section for the full list.
How well researched is DSIP?+
The evidence is classified as “preclinical”. 3 studies are cited on this page.
What is the molecular weight of DSIP?+
DSIP has a molar mass of about 848.8 Da.

Dossier
Legal · Structure · Sources.
DSIP is not an approved medicine in the EU and is not on the WADA Prohibited List. Importing it as a research chemical is a legal grey area — depending on the specific intended use, the German Medicines Act (AMG) may apply. In the absence of clinical data, a sound risk-benefit assessment is not possible.
Legal status varies by country and can change. This is not legal advice.
