Pricing FAQs
Which plan should I choose?
Free is perfect for trying Gilly. Monthly if you're new to GLP-1s and want flexibility. Annual if you're committed and want the best subscription value. Lifetime if you're in it for the long haul and hate subscriptions (most popular for serious users).
Can I upgrade later?
Yes! Start with Free or Monthly and upgrade anytime. If you're on Monthly for 12+ months, you'll have paid the same as Lifetime - so upgrade early to save money.
What happens after the introductory period?
Lifetime pricing will increase after the introductory period. Lock in at $59.99 now, and that's your price forever - you're grandfathered in with all future updates included.
Do you offer refunds?
Yes! Not satisfied within 30 days? Email us for a full refund, no questions asked. We're confident you'll love Gilly, but we want you to feel secure in your purchase.
