Reinvention Compounds Review: Lot-Numbered COAs, HPLC-Only Identity and Mixed Formats

Reinvention Compounds sells research peptides as freeze-dried powder in 3 mL vials, and its FAQ says it makes and fills them at its own facility in the Carolinas rather than relabeling imported vials. The catalog also includes a few non-vial items. Product pages frame the range as material for in-vitro laboratory research, not for human or veterinary use.

We looked at the homepage, the catalog, a product page, the COA library and two of its reports, the FAQ, the return policy and the terms. The lot-numbered report library is the strongest part of the site; identity testing and the mixed formats are the main gaps.

What Reinvention Compounds sells

The shop sorts about 35 products into six categories: Peptides, Longevity, Metabolic Research, GHK-Cu Research, Other Research Chemicals and Topical. Most are single peptides and multi-peptide blends, with vials from about $50 to $120 when we looked.

Alongside the vials, the store sells a topical serum, a capsule product and a liquid in dropper bottles. These are self-administration formats that do not fit research-use-only supply. Product pages list the vial size, CAS number, alternative names, storage temperature and the matching certificates, with order limits tied to stock.

Lot-numbered reports from Hyte Research Division

The COA library held 61 reports covering 36 compounds when we looked, each listed with a lot number such as 202608BPC10. Most open as PDFs and two as images. The BPC-157 product page shows the same reports, so a buyer can match a vial's lot to a certificate without asking support.

The two reports we opened carry the Hyte Research Division name, a report number, a lot number and dates, and list six results:

• Identity, purity and quantity by HPLC-DAD, with purity of about 99.2% on both.
• Endotoxin, sterility and heavy metals, all marked as passing.

There are two gaps. Identity is checked against a reference standard by HPLC, with no mass spec result showing observed against expected mass. And the FAQ says batch testing is done by the manufacturing partner's lab, so these are not independent reports, even though product text calls them third-party. The store does offer store credit for the full cost of a buyer's own test at an outside lab, if the report shows the company name and batch number.

Labeling and purchase checks

An entry gate asks visitors to confirm they are 21 or older and a qualified researcher, with an option to leave. The terms set the age at 21 in the United States and 18 in Europe. Product pages and the footer state that items are for in-vitro research only, not for human or veterinary use or diagnosis, and not evaluated by the FDA. The FAQ says the store gives no personal usage guidance, and product pages limit handling notes to storage.

The serum, capsule and dropper-bottle products undercut that labeling, since they are not ordinary research supply.

Ordering, shipping, refunds and support

Orders are processed on weekdays between 8 am and 4 pm Eastern and ship from the Carolinas. The same-day cutoff differs between pages, with noon on the homepage and 3 pm or 4 pm Eastern elsewhere. USPS is the only carrier named, products ship freeze-dried without cold packs, and international delivery covers Canada and Europe on DDU terms, with duties paid by the buyer.

Unopened products are final sale. Damaged or defective items must be reported within 7 days of receipt with the order number and photos, and approved claims get a full refund or replacement, with return shipping covered for the store's errors. The terms ask buyers to report delayed or missing parcels within 5 days of the expected delivery date, treat a parcel more than 30 days late as lost, and rule out reships to an incorrect address.

Support runs through a contact form and an email address. No legal entity, street address, phone number or list of payment methods is published.

Verdict: who Reinvention Compounds suits and what to check

Reinvention Compounds suits labs that want a lot-numbered report for each vial, with endotoxin and sterility results included. It is a weaker fit for buyers who need mass spec identity or reports from a lab independent of the manufacturer, and its serum and capsule products sit outside research-use-only supply.

Before ordering:

• Find your compound and lot in the COA library and open the report.
• Ask support which lot your order will ship from.
• Arrange outside mass spec testing if identity matters to your work, and claim the testing credit.
