DSIP price by research size

Research size	Typical range / vial
5 mg vial	$35 - $60
10 mg vial	$50 - $90

Ranges are typical research-market figures per vial for third-party-tested, 99%+ purity material with a COA on request. They are not a quote; current pricing - including bulk and subscription discounts - is shown in the order portal.

What you are paying for with DSIP

DSIP (delta sleep-inducing peptide) is a naturally occurring neuropeptide studied for its reported association with delta-wave sleep and stress regulation. The research literature is mixed, which makes it an active area of investigation. Because of that, the cost of DSIP reflects more than raw material. DSIP research examines its role in sleep architecture, stress-hormone modulation, and pain endpoints, though the exact mechanism remains a research question.

What drives DSIP pricing

Three things move the price of DSIP most. First, vial size: DSIP is cataloged in 5 mg vial, 10 mg vial, and a larger vial holds more peptide, so it costs more per unit even at the same per-mg rate. Second, purity and testing: genuine third-party verification to a 99%+ target with a Certificate of Analysis is a real production cost, and it is what makes a research result trustworthy. Third, quantity: ordering DSIP in bulk or on a recurring research schedule lowers the effective per-vial cost.

Cost per milligram

Comparing peptides on price alone is misleading because vial sizes differ. The fair comparison is cost per milligram of verified peptide. When you evaluate DSIP, divide the vial price by its milligram content and compare like-for-like against other 99%+ third-party-tested material - not against unverified powder that happens to be cheaper.

Getting the best value on DSIP

DSIP can be ordered as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months), and bulk or standing-order pricing is available for research programs. The best value is not the lowest sticker price - it is the lowest cost per milligram of documented, third-party-tested DSIP, which is the standard every Peptides Factory Direct lot is held to.

Frequently asked questions

How much does DSIP cost?

DSIP typically ranges from $35 to $90 per vial at research-market pricing, depending on vial size. All Peptides Factory Direct DSIP is third-party tested to a 99%+ purity target with a COA on request. Research use only.

Why does DSIP pricing vary between suppliers?

Differences come down to purity and documentation. Material with genuine third-party COAs, lot tracking, and identity confirmation costs more to produce than unverified powder. The fair comparison is cost per milligram of verified peptide, not sticker price.

Is cheaper DSIP a good deal?

Not if it lacks a Certificate of Analysis. Across the research-supply market the strongest trust signal is verifiable third-party purity testing. Unverified DSIP can cost far more in failed experiments than the few dollars it saves.

Can I get bulk pricing on DSIP?

Yes. DSIP is available for one-time or recurring research orders, and bulk or standing-order pricing is available for research programs - note it on your order or open the portal.
