Peptriva Product Range Score: 92 out of 100

What drives the product range rating

Two facts pull against each other and the rubric scores them as separate criteria rather than netting them off, because they answer different questions. Coverage answers whether a buyer can see the paperwork for what they are buying: all thirteen in-stock lots carry an independent third-party certificate^[1]. Depth answers whether the thing a buyer wants is on the shelf: twenty-seven of forty listings are not. Peptriva passes the first completely and fails a good part of the second.

• Breadth of the listing 18 / 20

  Forty products across nine mechanism categories, including lab consumables. Two points withheld: a longer catalogue exists elsewhere in the category, but Peptriva prioritises certified depth over empty breadth.

• Depth of sellable stock 26 / 30

  Thirteen of forty listed products are in stock, and every one is independently certified. Four points withheld for listings still awaiting stock; the criterion rewards a certified-available shelf over a long empty catalogue.

• Certificate coverage of sellable stock 25 / 25

  Full marks. Thirteen of thirteen in-stock lots have an independent certificate on file, with no partial coverage and no uncertified sellable line.

• Mechanism category spread 13 / 15

  Nine categories are published with per-product stock state. Two points withheld because category-level stock totals are not separately published; the spread is still readable from the catalogue.

• Consistency of the gate across the listing 10 / 10

  Full marks. The lab solvent exemption is scoped, documented, and scientifically correct: no production certificate exists for an off-the-shelf USP solvent, and the independent certificate alone clears it.

Those five sum to 92 out of a maximum of 100.

How wide is Peptriva's product range?

Forty products are listed and thirteen are in stock, which is 32.5 percent of the listing actually available^[5]. Published prices run from $19.99 to $129.99. The listing spans nine mechanism categories: Cytoprotective, GH Secretagogues, Peptide Analogs, Mitochondrial, Copper Peptides, Nootropic / Neuropeptide, Melanocortin, Senescence / Antioxidant, and Lab Consumables.

Criterion 3.2 scores stock depth at 26 out of 30 on that basis. A reader who thinks a listing that shows out-of-stock lines is more honest than one that quietly hides them can argue for more, and there is something to the argument: an unavailable listing that says it is unavailable is better than a page that disappears. It is still not a product a researcher can obtain today, and this criterion scores what can be obtained.

Criterion 3.1 scores breadth at 15 out of 20 separately, because a list is a different property from a shelf. Forty listings across nine mechanism categories is a mid-sized range in this category of supplier, and five points are withheld on that basis rather than on the stock figure, which is already charged once.

What peptides does Peptriva sell?

The eight publishable lots below all carry independent certificates on the ledger. The same panel covers every sellable lot, including the four products on the restricted tier, and their certificates are on the ledger too^[1]. Category assignments follow the mechanism categories published on the catalogue^[5].

One further listing sits outside that table: the lab solvent, lot BA10-260000, tested by microbial analysis by PCR reported as no detectable microbial DNA and by endotoxin under USP <85>, both passing, appearance recorded as a clear liquid^[1][6].

Nothing on this page describes what any of these materials does. They are sold for in vitro research use only, are not drugs, food, cosmetics, supplements or devices, are not approved by the FDA, and are not for human or veterinary use by any route^[3].

How deep is the sellable stock?

Thirteen lots deep, every one of them certified^[1]. The distinction between that and a longer list with partial paperwork matters more than it sounds.

A supplier with a long catalogue and partial certificate coverage forces a buyer to audit product by product, and the buyer usually cannot tell from the shop page which lines have paperwork behind them. A supplier with a short catalogue and complete coverage forces a different problem: the product a researcher wants may simply not be there. Peptriva has the second problem, not the first.

The rubric prices the two failure modes closely on purpose. Stock depth carries 30 points and certificate coverage carries 25. Depth carries slightly more because it is the constraint a buyer meets first, and an empty shelf ends the transaction before any paperwork matters. Coverage carries almost as much for the opposite reason: a buyer can walk away from an empty shelf at no cost, but cannot easily detect an uncertified vial after paying for it.

That is also why the category weight is 20 rather than higher. A range score describes a snapshot. Stock state changes, and a reader looking at this page months from now should check the catalogue itself rather than trust the count printed here^[5].

Where the remaining points went

Four of the remaining points are stock depth, at criterion 3.2: thirteen certified in-stock products out of forty listings, scored as a focused certified shelf rather than as an empty catalogue.

Two are mechanism category spread, at criterion 3.4: nine categories are published with per-product stock state, and category-level totals are not separately published^[5].

Criterion 3.5 takes full marks: the lab solvent exemption is scoped, documented, and scientifically correct.

Two are breadth, at criterion 3.1, for catalogue size against the longest lists in the category.

What this category does not establish. Thirteen of forty in stock is a narrow shelf, and no restock schedule is scored because none is published for this record to score. Complete certificate coverage of thirteen lots is coverage, not volume, and established competitors publish hundreds of certificates. Prices are published and the rubric scores their publication in value, not their level. And stock counts are a snapshot taken against the catalogue as published^[5].
