DSIP pricing FAQ
What is the cheapest DSIP right now?
S1 Research (Step One Ventures) currently lists DSIP at $2.20 per mg (DSIP 10mg(9.65mg), $22.00), the lowest of the 47 vendors we compare. The median is $5.80 per mg, so shopping around can save a lot.
How much does DSIP cost per mg?
Across 47 vendors, injectable DSIP ranges from $2.20 to $11.19 per mg, with a median of $5.80. Larger vials generally cost less per mg, which is why we normalize every listing to a price per milligram.
How much does a 5 mg vial of DSIP cost?
A 5 mg vial of DSIP costs between $15.90 and $80.00 across 30 vendors, with a median of $40.00. The cheapest is Tide Labs at $15.90.
Which DSIP vendors publish a COA?
44 of the 53 vendors listing DSIP say they publish certificates of analysis (COAs). A COA is the vendor’s own claim and can be copied or re-dated, so we also show independent test ratings (Finnrick) on each vendor page where they exist, and let you filter to “COA claimed” vendors.
Does DSIP come in forms other than injectable vials?
We also track sprays listings for DSIP. They are priced per mg of active ingredient too, but usually cost more per mg than lyophilized vials. Use the form filter above to compare them.
Is there human research on DSIP?
PubMed lists 462 papers on DSIP: 6 randomized controlled trials, 23 human clinical studies and 322 animal or lab-only studies, plus 1 registered clinical trial. We grade the evidence base as “Strong”: Several randomized controlled trials in humans, often summarized by meta-analyses. This describes how much research exists, not whether it works.
Is DSIP legal and safe to use?
DSIP is sold for laboratory research use only. PeptideComps compares prices and does not give medical advice, and we can’t vouch for any product’s quality or legality — check the rules where you live.
