PeptideRadar is a research-use-only reference for peptide mechanism, indexed literature, protocol-design notes, and vendor transparency. No coaching. No health claims. Just what the papers say, what the communities report, and where to check before you source.
A 15-amino-acid fragment of gastric-juice protein BPC. Heavily cited in rat soft-tissue injury models; human RCT evidence is limited. Walks the literature, the FDA position, and the reconstitution math.
Approved in 2010 for HIV-associated lipodystrophy (brand: Egrifta). 2 mg/day subcutaneous reduced visceral fat ~15–18% in pivotal trials. The peptide with the cleanest literature, and the clearest compliance guardrails.
"TB-500" as sold by research-chemical vendors is typically an acetylated 17-mer fragment, not full-length Tβ4. Mechanism (actin sequestration), key rodent data, and why the "healing peptide" framing oversimplifies.
Pentapeptide. Ghrelin receptor (GHS-R1a) agonist. Cleaner side-effect profile than GHRP-6 or hexarelin in the published work. What the pharmacokinetics imply for dosing cadence, and what we don't know about long-term use.
Approved GLP-1 analog (Novo Nordisk). STEP trials showed ~15% weight loss at 68 weeks. Why compounded and "research-use" sourcing is a legal minefield, and how to read a vendor COA against pharmacopoeia standards.
We evaluate research-peptide vendors on four axes: third-party COA availability (HPLC and mass-spec), shipping-and-payment reliability, customer-reported lot-to-lot consistency, and response to negative findings. Every review discloses affiliate status explicitly.
Every page on PeptideRadar exists to answer one question: what does the literature actually say? We do not coach dosing. We do not make health claims. We report mechanisms, cite indexed sources, flag what's strong evidence vs mouse-model vs community anecdote, and note regulatory status honestly. If a vendor ships us a bad lot and we test it, we publish the result.
A short Friday email: one new indexed paper we found worth reading, one vendor update (price, COA, shipping), one community signal (Reddit / Discord / telegram), and a one-line take. No hype. No push. Unsubscribe anytime.
