Plum Labs Research Review: Lot-Level COAs From Three Named Labs and a Researcher Gate

Plum Labs Research is run by Plum Collective Holdings, LLC from a street address in New Rochelle, New York. It sells research peptides as freeze-dried powder in 3 mL vials, along with blends, a few raw 1 g powders and reconstitution solutions, and states that everything is for laboratory research only.

We looked at the homepage, the shop, two product pages, a category page, the COA guide, the FAQ and refund page, and the terms. The store's strength is lot-level paperwork from named labs; its gaps are identity data on product pages and some descriptive copy.

What Plum Labs Research sells

The shop listed about 45 items, sorted into groups such as copper peptides, neuropeptide research, metabolic research, regenerative research, laboratory blends and reconstitution solutions. Examples include Epithalon, DSIP, GHK-Cu, NAD+, a CJC-1295 and Ipamorelin blend without DAC, Cagrilintide and Eloralintide. A cosmetic research materials group holds raw powders such as AHK-Cu and Syn-Ake rather than finished skin products.

Listed prices ran from about $5 for sterile solution to $149 for the largest blend. No founding year or owners are named.

Lot reports from Kovera Labs, ILS-Labs and Freedom Diagnostics

The COA guide names three labs and explains how to check a report number on the issuing lab's site. It lists the tests the store uses: HPLC purity, identity by mass spec, net content, sterility, endotoxin, heavy metals by ICP-MS and a three-vial conformity check, with a fentanyl screen on some batches. Panels vary by product and batch.

Each product page shows the lot currently shipping and earlier lots. The Epithalon 10 mg page, for example, showed lot PLR-ET-102 as currently shipping, tested in June 2026 at about 99.46% purity and 10.64 mg net content, plus an archived Freedom Diagnostics lot from March 2026. Each lot links its full report PDF.

Two gaps stand out:

• Identity appears as a test category, and the sample COA in the guide uses LC-MS, but the product page summary shows no observed versus expected mass.
• A compound not yet in stock had no report on its page.

Labeling and purchase checks

A gate asks visitors to pick a researcher type and confirm they are 21 or older and buying for in vitro or laboratory research. Research-only notices appear on product pages, in the footer and in the terms, which bar resale for human or veterinary use. The site says it is not a compounding pharmacy, and we saw no dosing content.

Some product descriptions, though, go beyond identity and handling to summarize study findings, which falls short of strict research-use labeling.

Ordering, shipping, refunds and support

Orders ship by UPS from New Rochelle to US and Puerto Rico addresses, and eligible orders can be processed the same day. Shipping is free over $200; other rates appear at checkout. The terms say risk passes to the buyer once the carrier has the parcel, and optional package protection is offered at checkout. Payment methods are not listed.

All sales are final once an order leaves the facility. Damaged, incomplete or wrong orders must be reported within 72 hours of carrier delivery, with photos of the box, label, products and lot numbers. The store then chooses between a replacement, store credit or a full or partial refund, paid to the original method in about 7 to 10 business days. Parcels marked delivered and carrier delays are excluded.

Support is by email, Monday to Friday and on Saturday until 3 PM Eastern.

Verdict: who Plum Labs Research suits

Plum Labs Research suits labs that want to see the exact lot they will receive, with a report they can check against the issuing lab. It is a weaker fit for labs that need identity results visible before ordering, or more flexible returns.

Before ordering:

• Match the lot number on your vial to the report on the product page.
• Check the report number with the issuing lab.
• Ask support for the identity result for your lot if the summary doesn't show it.
