Street names: N-hexanoic-Tyr-Ile-(6) aminohexanoic amide, PGL-500

Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines

⚡What it does

Potent HGF/c-Met-pathway activator in animal studies — 'brain repair' nootropic claims
Marketed for cognition and neuroprotection

c-Met activation is also a tumor-growth pathway — the theoretical cancer concern is serious
Essentially zero human data
Microgram-to-milligram dosing confusion = real overdose risk

Substance	Class	Top risks	Street price
DIHEXA	'Research chemical' — no human approval	c-Met activation is also a tumor-growth pathway — the theoretical cancer concern is serious; Essentially zero human data	~$40–$100 per vial grey-market
BPC-157	Unscheduled — 'research chemical', not approved for human use anywhere	ZERO human clinical trials — all human use is anecdotal self-experimentation; Unregulated synthesis: purity, sterility, and actual content unverified	~$20–$60 per 5 mg vial grey-market
TB-500 (Thymosin Beta-4 fragment)	Unscheduled — 'research chemical'; banned in sport	No approved human use or trials — same self-experimentation class as BPC-157; Growth/repair factor activity raises theoretical cancer concerns	~$25–$70 per vial grey-market
Melanotan II	Unscheduled	Unapproved — regulators (FDA/TGA/MHRA) have issued warnings and seizures; 'Melanotan rage' — documented mood/aggression changes	~$20–$50 per 10 mg vial grey-market
GHRPs & GH Secretagogues	Unscheduled — 'research chemicals'	All are 'research chemical' grade unless pharmacy-sourced: purity unknown; Water retention, carpal-tunnel symptoms, insulin resistance with chronic use	~$15–$40 per vial grey-market
IGF-1 & MGF analogues	Unscheduled — 'research chemicals'; IGF-1 is Rx	Hypoglycemia — IGF-1 pulls blood sugar down hard; dangerous in diabetics; Theoretical but serious cancer concerns — IGF-1 feeds tumor growth	~$30–$80 per vial grey-market

Street prices are regional estimates. Potency and cuts vary constantly.

These brands are sold as this compound. Same molecule, different label and supply chain — quality varies enormously between them.
