How to read peptide prices
The sticker price is almost meaningless on its own β what matters is cost per milligram of actual peptide. A "$25 vial" of a 2 mg peptide ($12.50/mg) is far more expensive than a "$70 vial" of a 30 mg peptide ($2.33/mg). Always divide price by total milligrams before comparing.
price Γ· total mg in the vial/kit. The single most useful number. Use our reconstitution calculator to turn mg into per-dose cost.
Multi-vial kits (e.g. BPC-157 10Γ5 mg) lower the per-mg cost but cost more up front. Singles are cheaper to try, pricier per mg.
Oral SARMs/compounds sold as capsules (60Γ10 mg = 600 mg) look cheap per mg but aren't injectable peptides β different bioavailability.
What actually drives the price
- Purity & testing. Third-party HPLC/MS testing with published COAs costs the vendor money β and is the difference between research-grade and gray-market powder. Cheaper isn't better if purity is unverified. See how to verify peptide quality.
- Vendor type. Research-chemical vendors (like Swiss Chems) price per mg; compounding pharmacies price per prescription and cost more but are physician-supervised.
- Compound rarity. Bioregulators and novel peptides (IGF-1 LR3, Pinealon) cost more per mg than commodity peptides (GHK-Cu, GHRP).
- "Too cheap" is a red flag. Prices far below the ranges above usually mean underdosed or impure product. Demand a recent COA.
What about Ozempic, Wegovy & tirzepatide?
The GLP-1 weight-loss drugs aren't sold as research peptides β they come from pharmacies, and pricing is a different world (brand retail ~$1,000+/mo vs compounded alternatives). We cover that in depth in compounded semaglutide pricing, Ozempic alternatives, and the compounding pharmacy guide.
