Peptide Giants Review: Lot-Numbered Vanguard Reports, 21+ Gate and US-Only Shipping

Peptide Giants is a research peptide store with a mailing address in Tampa, Florida. It sells freeze-dried compounds as single vials and 10-vial kits, plus supplies such as reconstitution water and 0.6% acetic acid, and it presents everything as material for laboratory and in-vitro research, not for human or veterinary use.

We looked at the homepage, the shop, a product page, the lab reports page, the shipping, refund and payment pages, the about page and the terms. The strongest point is a lot-numbered report directory; the main gap is that mass spec identity results are summarized rather than shown.

What Peptide Giants sells and how the catalog is laid out

The shop runs across five pages of about 12 listings each, so the catalog holds roughly 50 to 60 items. Single vials include BPC-157, AICAR, AHK-Cu, PT-141, IGF-1 LR3, Selank and Sermorelin, along with blends sold under shorthand names such as GLOW and KLOW. Some GLP-1 class compounds are listed under shorthand codes.

A 5 mg BPC-157 vial cost about $20 when we looked, most single vials sat between $30 and $90, and 10-vial kits were about $300. Product pages give the strength, a storage note and a short research-context description. No staff names or founding year are published.

Vanguard Laboratory reports, batch numbers and what is missing

The lab reports page lists 45 certificates in a table. Each row gives the compound, a batch number in the store's own format (for example PG-6012), a purity figure, a test date and, on most rows, Vanguard Laboratory as the issuing lab. Test dates ran from May to August 2026, and listed purity ranged from about 96.6% for one hexarelin lot to above 99.8% for AICAR. Most rows open a PDF, while a separate image gallery and one tesamorelin entry link to Janoshik verification pages instead.

The table does not say which methods were used. The BPC-157 product page adds a summary panel with HPLC purity of 99%+, an LC-MS identity result marked "passed" and a net-content figure, tied to lot 24B-1107 and dated November 2026. That lot code does not follow the directory's PG format, the observed mass is not printed, and the link to the full report opens an image file rather than a PDF.

Research-use labeling and the entry gate

A gate on entry asks visitors to confirm they are 21 or older and a qualified researcher, with an exit option for anyone who is not. Research-use-only notices sit beside the buy button, in the footer and in the terms, and the about page states that the store gives no medical, treatment or clinical guidance. No dosing content or effect claims were seen on the pages reviewed.

The terms limit use to non-clinical research, cap the store's liability at the price of the affected product and deny refunds where research-use terms are breached. The catalog is vials and lab supplies only, with no sprays, pens or capsules.

Ordering, shipping, refunds and support

Verdict: which labs Peptide Giants suits

Peptide Giants suits US labs that want a lot-numbered report for each compound and a full set of written policies. The directory is easy to scan, and most reports come from the same lab. The weak spots are the missing method details, the mismatched lot format on the product page and the lack of visible mass spec numbers.

Before ordering, match the batch number on the vial to a directory entry, open the full report to confirm the method and observed mass, and verify the certificate with Vanguard Laboratory or through the linked Janoshik page.
