Matched peptides
Highest match first. The score is the share of this entry's targets the peptide carries; it is a match score, not a verdict.

What the quotation does
For the peptides you pick it lists the products vendors in your country offer, each clickable, and ranks them three ways: best price (product price per mg), best value (price per mg after the water, syringes or needles the format forces), and best overall (value, days usable after opening, handling and quantity, weighted in the open). Every number's working is printed under it.
