Short answer: Buying through third-party marketplaces carries the usual risks of unverified sellers, including no guarantee of an authentic product or access to the official 60-day refund policy.
Why authenticity is a genuine concern for a proprietary-blend supplement
Since the exact formula composition isn't independently verifiable at a glance, buying from an unverified seller adds a real risk of receiving a counterfeit or altered product.
Why the guarantee specifically doesn't transfer to third-party purchases
Jelly Force is available online through the official website — a direct statement worth taking as the recommended, guarantee-eligible purchase channel.
💡 Worth knowing: this same caution about third-party marketplaces is worth applying broadly across any proprietary-blend supplement purchase, not just this specific product.
