Know what a peptide actually does before you decide anything.
PeptideInfo is a free reference for 72 research peptides. Each entry explains the mechanism in plain words, grades the evidence by study type, lists the protocols reported in the literature, and shows the regulatory status in the US, EU, UK and UAE. References link to PubMed where a record is available.

1 tool →How an entry is written, and why you can trust the grade.
We do not rate peptides. We grade the studies behind each claim by their design, from randomised human trials down to anecdote, and each grade points at the papers it rests on. When a reference cannot be matched to a PubMed record, its identifier is removed and the entry says so.
Sources
Peer-reviewed papers, regulator databases and clinician commentary. Community reports are never used as evidence.
Verification
PMIDs are resolved against PubMed. Title and year are taken from the record. Mismatched identifiers are removed and logged in the entry’s changelog.
Grading
Each indication is graded by the strongest study type behind it: human RCT · human open-label · animal controlled · in vitro · anecdotal. A grade is only as strong as its weakest link.
Dated
Regulatory rows and the entry itself carry the date they were last checked, where recorded. Old is visible, not hidden.

Calculators that show their working.
Enter what is on your vial and what you plan to draw. The calculator shows the concentration, the volume and the syringe units, with each step written out. It never suggests a dose.

- Concentration = 5 mg ÷ 2 mL
- 2.5 mg/mL
- Volume = 0.25 mg ÷ 2.5 mg/mL
- 0.10 mL
- On a U-100 insulin syringe (100 units per mL)
- 10 units
Doses per vial at this amount: 20. This example computes from the values shown; it never suggests a dose.
