DSIP
Limited human dataA fifty-year-old sleep peptide with genuine and reproducible effects for some people, and still no confirmed receptor or modern protocol.
What it is
DSIP, short for delta sleep-inducing peptide, is a nine-amino-acid neuropeptide discovered in 1977. Researchers pulled it from the blood of rabbits whose brains had been electrically stimulated into deep sleep. It was named for its apparent link to delta waves, the slow brain rhythms of deep sleep.
How it works
Here is the honest answer: nobody has confirmed what DSIP binds to. No receptor has ever been pinned down. Yet its effects on sleep, stress response, and even alcohol withdrawal have kept scientists curious for decades. Without a known receptor, the rest is observation rather than mechanism.
What people report
- ✦Some people report genuine improvements in falling asleep and sleeping deeply
- ✦Studied historically for stress and alcohol-withdrawal support
- ✦Side effects are rarely reported across decades of use
- ✦Cheap on the research market, so the cost of testing it is low
Typical use
Community use is largely sleep-focused around bedtime, but no modern dosing framework has been validated, and its very short lifespan in the body complicates timing.
Dosing reference
No approved or validated dose exists. Its half-life is minutes, which has complicated clinical use from the start. Verify any product and dosing guidance carefully.
Reference only — not a recommendation. Verify via primary sources.
Watch for
The response is bimodal: when it works, it seems to really work, but for many people it does little. Fifty years of trials never converged on a decisive result. That long a runway with no convergence is the honest signal that the effect is narrow, real, and unpredictable.

BPC-157
Healing & recoveryThe repair peptide everyone in the gym talks about — powerful in rats, still unproven in humans.
BPC-157 is a short chain of 15 amino acids. It is not a natural hormone your body makes on its own. It was built in a lab as a fragment of a larger 'body protection compound' first found in human stomach juice in the 1990s. Vendors sell this engineered piece, not a natural sequence.
How it works (optional detail)
In animal studies, BPC-157 seems to nudge faster blood-vessel growth at injured spots, which is the body's first step in healing. It also appears to quiet inflammation. The idea is that by tickling repair pathways rather than ordering one single thing, it helps tendons, ligaments, and gut lining recover speedier than they would on their own.
Dosing reference: Common community dosing is a few hundred micrograms a day, usually injected near the site or into belly fat. There is no approved human dose.

Concentration: 2.500 mg/ml (5mg in 2ml)
To get 1mg, draw:
0.400 ml
≈ 40 units on a U-100 insulin syringe
