Brand Analysis
Old School Labs makes Vintage Burn — a more honest budget fat burner than most. Green coffee bean extract, green tea EGCG, and caffeine form a core thermogenic stack with real evidence behind it. Raspberry ketones are included despite no human evidence — honest marketing folklore rather than deception.
The retro bodybuilding aesthetic is well executed and differentiates them from the clinical-claims brands. Transparent label relative to budget tier competitors.
Value is the core proposition. At ~$1.50/serving, Vintage Burn undercuts Instant Knockout by ~30% for a modestly less clinical formula.
