FAQ

Are these products meant for personal use?: No. Everything we sell is for laboratory research only and is not for human consumption. The catalog reflects what we source for our own research. It is not a recommendation that anyone take any of it.
Why don’t you post COAs?: Our batches are tested through group testing, so the lab report carries our supplier's name rather than ours. Our suppliers have asked us not to advertise them online, and posting the reports would do that. Every batch is still tested for mass, purity, sterility, endotoxins, and heavy metals, and has to meet our spec: 98% purity or higher, and no more than 10% under the labeled amount. How we test →
Why are your prices so low?: Testing one vial at a reputable lab costs $300 to $1,700, depending on how much of the panel you run. Instead of paying that alone, we join groups of 50 to 150 researchers buying the same batch and split the cost. When we move to testing under our own name, that cost will fall on us alone and prices will go up slightly.
Can I test a vial myself?: Yes, and we encourage it. If your result from an accepted lab shows purity below 98%, or more than 10% under the labeled amount, we refund the product cost. A vial that tests over the label isn't refunded. See the refund policy for the labs we accept and how to file a claim.
Why do peptides ship as a powder instead of a ready-made solution?: Peptides in solution degrade — the bonds that make them biologically interesting are the same bonds that hydrolyze in water. Freeze-drying removes the water and locks the compound in a stable cake that holds its assay for months and survives shipping without a cold chain. The trade-off is one extra step on your end: reconstitute the vial with bacteriostatic water before testing.
What is bacteriostatic water?: Sterile water with 0.9% benzyl alcohol — the benzyl alcohol prevents microbial growth in the vial so a multi-dose vial stays usable for several weeks. It's the standard solvent for research peptide reconstitution. We sell 10ml and 3ml vials.
How much bac water do I add to a vial?: It depends on the peptide. The cheat sheet lists the recommended volume for each compound — typically 2 or 3 ml per vial.
What syringes do I need?: Two sizes of insulin syringe: 1 ml for reconstituting, and 0.5 ml for research use, plus 0.3 ml for amounts under 10 units. We don't sell these; the supplies checklist links the ones we suggest.
How long is reconstituted material stable?: Most peptides are stable refrigerated (2–8°C) for 2–4 weeks after reconstitution; some shorter. When in doubt, treat as 14 days. Label every vial with its reconstitution date.
Should I store the powder vials in the fridge before reconstitution?: Yes — sealed lyophilized vials hold longest when refrigerated. The shipped powder is stable at room temperature for transit, but long-term storage should be 2–8°C, away from light.
Do you carry a peptide I can’t find on the site?: Possibly not yet. The cheat sheet has a “Request this peptide” button on every row we don't currently carry — file a request and we'll consider it for the next lot.
