Planet Peptide

Planet Peptide is operated by Neos Bio, LLC out of Bradenton, Florida, and its origin is more personal than most vendors in this space: the company says it was founded in memory of the founder's brother Chad, who died in 2022 after health symptoms it describes as having been overlooked for years, and that loss is the stated reason the catalog leans toward metabolic and neuropeptide research compounds. The current lineup runs roughly fifty SKUs across single-vial and ten-vial bulk formats, spanning GLP-1-class research peptides such as Tirzepatide-RUO, Retatrutide-RUO, Cagrilintide-RUO, Semaglutide-RUO, and a CagriSema blend, recovery and growth peptides including BPC-157, TB-500, CJC-1295, Ipamorelin, and GHK-Cu, and a smaller neuropeptide line covering Semax, Selank, and Cerebrolysin. Orders placed Monday through Friday ship the next business day; the company is closed weekends and states it sells exclusively through its own website, warning buyers that any other storefront using its name is unauthorized. On testing, Planet Peptide does not publish a dedicated certificate-of-analysis page on its own site, a gap flagged by the vendor-comparison site PickPeptides, which lists it as lacking third-party COAs despite an aggregate 3.9-out-of-5 rating across twenty-five buyer reviews collected there. Independent purity data exists outside the company's own site: the batch-testing tracker Finnrick logs results for Planet Peptide across nine different peptides. Buyer feedback skews positive on logistics, with most reviewers describing two-to-four-day shipping and responsive support, but it isn't uniform: one buyer reported a Retatrutide vial arriving gelled after a three-week delay, and another said certificates posted on the site had gone stale by more than six months. Planet Peptide's catalog spans both single-vial and multi-vial bulk formats with substantial pricing differences between tiers — a structure atypical among peptide suppliers on the platform. Bulk multi-vial pricing (10-vial packs, verified against single-compound URLs): TB-500 bulk 10-vial at $1/mg, BPC-157 bulk 10mg at $2.23/mg, GHK-Cu from $0.50/mg (single-vial) rising to $3.75/mg at bulk-10 tier. Single-vial pricing is higher but still competitive for several compounds: Semax from $4/mg, MOTS-c from $4.25/mg, Selank from $4.50/mg, Tirzepatide from $3/mg (60mg vial), Semaglutide from $7/mg (10mg vial), Retatrutide from $6.45/mg (20mg vial). Researchers needing larger quantities will find the price-per-mg drops sharply at the multi-vial tier for the tissue-repair and GH-secretagogue staples.
