Price per mg
Aggregates of single-vial research-use listings. A price counts only if it was still shown on the seller's product page when we re-fetched it on 2 Oct 2026 (first recorded 7 Aug 2026). Prices are converted to price per mg so vial sizes compare fairly. Sizes with fewer than three sellers are not shown. Bulk powder, lab reagents, multi-vial packs and approved brand pens are excluded.

Worked example: cost per week
Arithmetic illustration only, not a recommended dose: at 2 mg per week from a 10 mg vial, at the median price per mg of $9.88, the peptide itself costs about $19.76 per week (2 × $9.88). Doses used in studies are on the dosage page.
Why prices vary
- Brand-name prices depend on insurance coverage, manufacturer programs and pharmacy; compounded versions are priced differently.
- Bigger vials usually cost less per mg, but only if the whole vial is used before it expires.
- Prices change often, which is why every figure here carries the date it was checked.
