Sleep & Circadian Research Peptides
One compound sits here, DSIP, and it’s out of stock. It hasn’t got a third-party purity result either. Both of those are worth knowing before you read any further.
We’re not going to pad this category out with compounds that belong somewhere else to make the shelf look fuller. When DSIP is back and when it has been assayed, this page will say so.
What DSIP is
| Compound | DSIP, delta sleep-inducing peptide |
| CAS | 62568-57-4 |
| Molecular weight | 848.8 g/mol |
| Strengths | 2mg, 5mg and 10mg |
| Purity | Not third-party tested. No purity claim applies. |
| Availability | Out of stock |
Identity's verifiable through PubChem.1 Everything else on this page follows from those two blanks in the table.
Why there is no purity figure, and why we are not filling it in
Every other category on this site has at least one compound with a named laboratory and a named batch. This one doesn't.
We could put the manufacturer's own claimed purity here and let it read like an independent result. Several things on this site would look better that way. A supplier's self-declared figure and a third-party HPLC report are not the same document, and presenting one as the other is the single easiest way to mislead in this market.
So the column stays blank until an assay exists. That's the whole rule and we're not bending it here.
What the name does and does not tell you
DSIP stands for delta sleep-inducing peptide. The name comes from the context in which it was first described, not from an established effect in people, and a compound name isn't evidence.
We're not going to summarise a sleep literature for you here. The compound has no purity result and no stock, and writing a research section for something you cannot buy and whose identity we have not independently confirmed by assay would be putting the interesting part first and the honest part last.
Regulatory status in Canada
Health Canada regulates injectable peptides as drugs and has stated in writing that labelling one "for research use only" doesn't remove it from that regulation.2 DSIP is supplied for laboratory research use only and is not approved for human or veterinary use.
DSIP appears by name on the seized-product list in Health Canada's notice.3 We publish no dosing, no protocols and no stacks.
When this category is worth coming back to
Two things would change it: DSIP back in stock, and a third-party assay with the laboratory and batch named. Until then, this page is here to tell you the truth about a shelf that hasn't got anything on it.
If you're looking for compounds that are in stock and tested today, healing and recovery research peptides has three of three certified, and longevity and cellular research peptides has two of two.

Common questions
Can I buy DSIP right now? No. It's out of stock.
Does it have a certificate of analysis? No. It's the only compound in this category and it has no third-party purity result.
What does DSIP stand for? Delta sleep-inducing peptide. That's the name it was given when first described, and a name is not a finding.
What strengths does it come in? 2mg, 5mg and 10mg, when it's in stock.
Is it legal in Canada? Health Canada regulates injectable peptides as drugs, and research use labelling doesn't change that. DSIP is named on Health Canada's seized-product list. Nothing here is approved for use in a person and we won't supply dosing.
Is it safe? No safety profile has been established, and there is no purity assay either, so this compound has less information behind it than anything else on the site.
