Prices are for research materials sold for laboratory use only. PeptidePub may earn a commission from vendor links or codes at no cost to you. This does not affect testing grades or rankings. See our methodology. Best value is the lowest $/mg among vendors with verifiable published testing; Best tested is the vendor passing the most of our 7 testing checks.
Which size should I buy?
Bigger vials cost less per mg. Right now the cheapest 60 mg option is $1.50/mg, about 83% less per mg than the cheapest 5 mg option at $9/mg.
The saving only counts if you can use the vial within its storage window. This peptide's guide lists a reconstituted use-within window of single-dose vial or pen: use as supplied; multidose KwikPen instructions are product-specific. See handling and storage.
Smaller vials cost more per mg but waste less if a vial sits open past its window. Filter to 5 mg and Filter to 60 mg.

The catalog is refreshed daily from vendor data sweeps, and the page reflects the current catalog values at build time. When vendor pricing or codes change, the comparison and cheapest-offer answer update from the same source data.
