New to Vial Guide? Here is how the site works and what to read first.
Every number says where it came from
The same dose range means very different things for an approved drug and for a peptide only tested in rats, so every dose carries a tag.
From an approved product’s prescribing information. A regulator reviewed the dose for a specific use.
Used in a published human study. Tested in people, but not approved for this use.
Commonly reported, not established. No safety or efficacy data stand behind it.
Where to go
Look up a peptide
42 peptides and 6 blends, searchable by name, brand or alias. Each page has the dose, cycle, mixing math, status, human studies and cautions.
OpenStart from a goal
Eight guides compare the options for one goal, with example protocols worked out to the syringe.
OpenDo the math
Vial, water and dose in; syringe units out. It also plans how many vials a run takes and exports a dose calendar.
OpenCompare side by side
Up to three compounds at once: evidence, status, dose, cycle and half-life.
OpenCheck a combination
Flags documented overlaps, like two drugs on the same receptor or the same peptide inside a blend, and builds one tracking checklist.
OpenKeep a dose log
Track mixed vials and their discard dates, the doses you take and where you injected. It stays on your device.
OpenBefore you inject
Sites, rotation, technique and getting rid of needles safely.
OpenRead a lab report
What a certificate of analysis should show, and the red flags.
OpenLook up a term
Plain definitions of 503A, half-life, U-100 syringes and the rest.
OpenThree things to get right
- Units are not millilitersOn a U-100 insulin syringe, 10 units is 0.10 mL. Mixing the two up has caused 5 to 20 times overdoses. The calculator always shows both.
- Water changes the units, not the doseThe same dose takes more units in a vial mixed with more water. Work out the units again whenever the water or the vial size changes.
- Check the statusMany compounds here aren’t approved for human use, and some are banned in sport. Each page shows its approval, US compounding and WADA status, with the date it was checked.
What this site isn’t
Vial Guide is a free reference. It doesn’t sell anything, doesn’t recommend doses and isn’t medical advice. Read the disclaimer, and talk to a licensed clinician before using any of these compounds.
