Start with the same specifications
Compare the same compound, formulation and nominal vial strength. A familiar short name is not enough: CJC-1295 with DAC and CJC-1295 No DAC are separate product families. Blend ratios also matter; two 10 mg blends can contain different component quantities.
Check the supplier’s full specifications and batch documentation. A price comparison does not establish identity, purity, sterility or research suitability.
Single vial or multi-vial kit?
A kit price is the price of the whole pack. Five 10 mg vials contain 50 mg nominal mass, not 10 mg. Compare the amount you must buy as well as the unit cost.
Illustrative example, not a supplier offer: a US$200 kit containing five 10 mg vials is US$40 per vial and US$4 per mg. A single 10 mg vial at US$50 is US$5 per mg but requires less upfront spend.
Yopepi excludes unclear bundles and variants without reliable size and price information. Use the price per mg calculator to compare whole-pack totals.
Check shipping and checkout taxes
The comparison shows published USD listing prices, excluding shipping and checkout taxes. Check the final total for your delivery address, minimum spend, coupon conditions and any extra fees.
Illustrative example: a US$50 vial plus US$20 shipping costs US$70 before tax. A US$55 vial plus US$5 shipping costs US$60 before tax. The second listing has the higher headline price and the lower delivered subtotal.
Read the observation time
Connected feeds are scheduled for daily checks, rather than live checkout monitoring. Each offer carries an observation timestamp. A failed refresh does not make a previous observation current, and availability may change between checks.
“Not confirmed” availability is not a promise of stock. Always reopen the supplier listing before procurement.
Understand the coverage
“Best price found” applies to eligible listings in Yopepi’s connected coverage for the selected size and filters. It is not a claim to monitor every US supplier. Directory inclusion is not an endorsement, and paid advertising does not improve a supplier’s price ranking.

Keep markets separate
The US comparison uses USD listings. The Australian comparison uses AUD listings. Yopepi does not convert currencies or assume that cross-border shipping is available.
