Supplement Refund Policy
Last Updated: July 25, 2026
At Thirmik, your satisfaction is our priority. We stand behind everything we make, and we want every customer to feel confident in their purchase from the moment they place an order.
Our Promise
If you are not completely satisfied with your Thirmik purchase, we are here to help. This policy applies to all supplements sold through thirmik.com and covers your rights as a customer, our obligations as a brand, and the process for resolving any issues that arise.
By placing an order with Thirmik, you acknowledge and agree to the terms outlined in this policy. We reserve the right to update this policy at any time. Changes take effect immediately upon posting to our website.
The 90-Day Satisfaction Guarantee
Try your first supply risk-free. If you use your Thirmik supplement consistently as directed and are not satisfied with your results, you may be eligible to submit a guarantee claim within 90 days of your original order date.
Important: The 90-day window starts from the date of your very first order and does not reset with each new shipment. Recurring subscription orders placed after the initial purchase are not separately covered under this guarantee.
Eligibility Requirements
To qualify for a guarantee claim, you must meet all of the following requirements:
- Submit your claim within 90 days of your original order date.
- Use the product consistently and as directed throughout the period.
- Provide proof of purchase.
- Provide a brief description of your experience and how you used the product.
- Submit your claim directly to Thirmik before initiating any chargeback or payment dispute.
Supporting Evidence
Supporting documentation is optional but helps us review your claim more quickly. Helpful examples include:
- Usage notes or a description of your routine.
- Photos.
- Recent health records or test results you already have.
We understand many clinical tests are performed infrequently, often a year or more apart, so we will never require new testing to process your claim.
Claims submitted without supporting evidence will still be reviewed but may require additional information and take longer to process. We reserve the right to request additional documentation before approving any claim.
How to Submit a Claim
Email us at hello@thirmik.com or use the contact form at thirmik.com/contact with:
- Your order number.
- A description of your experience.
- Any supporting documentation (optional).
We respond within 1 business day, and claims are typically reviewed within 3 business days.
What Happens If Your Claim Is Approved
If approved:
- Your refund will be issued to your original payment method within 5–10 business days.
- Original shipping, handling, and processing fees are non-refundable.
- No physical return is required due to the nature of health products.
- You may keep, gift, or safely dispose of the product.
Guarantee Exclusions
- Claims submitted after the 90-day window.
- Products not used consistently or as directed.
- Change of mind, subscription confusion, or medical advice from a healthcare provider.
- Fraudulent or abusive claims.
- More than one refund per product, customer, household, or payment method.
- Recurring subscription orders placed after the first shipment.
- Promotional bundles, final sale offers, or replacement orders.
- If free promotional items were included (such as Buy 2 Get 1 Free), their retail value may be deducted from the refund.

Damaged, Defective, or Incorrect Products
If your order arrives damaged, defective, or contains the wrong item, contact us within 7 days of delivery.
To File a Claim
- Email hello@thirmik.com.
- Include your order number.
- Include clear photos or video of the issue.
- Include a photo of the shipping label and packaging.
Once reviewed, we will replace the item at no cost. If a replacement is unavailable, we may instead issue a refund.
Subscription Billing (If Applicable)
By enrolling in a Thirmik subscription, you agree to recurring charges at the interval disclosed during checkout.
Renewal Reminders
We send an email reminder 3 days before every renewal. It is your responsibility to cancel or modify your subscription before renewal if you do not wish to be charged.
Renewal Orders
Recurring subscription orders are not covered by the 90-Day Satisfaction Guarantee.
However, if your renewal order is unopened, contact us within 14 days of delivery. At our discretion, unopened renewal orders may qualify for a partial refund or store credit.
Managing Your Subscription
- Cancel, pause, skip, or modify your subscription anytime through your account or by contacting us.
- Cancellations must be made at least 24 hours before the next billing date.
- Cancellations stop future billing only and do not reverse charges already processed.
- Introductory pricing automatically converts to the standard subscription rate unless cancelled before renewal.
Lost, Delayed, and Stolen Packages
Lost or Severely Delayed Packages
If tracking has not updated for 30 consecutive days, we will file a carrier claim and arrange a replacement shipment at no additional cost.
Stolen Packages
If tracking shows "Delivered" but you cannot locate your package, contact us immediately. We will investigate with the carrier. Compensation requires supporting evidence and cannot be guaranteed.
Incorrect Address & Unclaimed Packages
- Please verify your shipping address before placing your order.
- Address changes cannot be guaranteed after 2 hours.
- Orders sent to incorrect addresses provided by the customer or left unclaimed are not guaranteed to qualify for refunds or replacements.
Order Changes & Cancellations
Orders are processed quickly, so we cannot guarantee changes or cancellations once placed.
If you need to modify an order, contact hello@thirmik.com as soon as possible.
Once an order has shipped, it cannot be changed or cancelled.
Refusing delivery or failing to claim a package does not constitute a return and is not eligible for an automatic refund. Duties, customs fees, and import taxes are non-refundable.
Medical & Health Restriction Cases
Consult your healthcare provider before using any Thirmik supplement.
If your doctor advises against using the product because of a medical condition or medication interaction, contact our support team. We will review your case individually as a courtesy.
Medical advice alone does not automatically qualify for a refund.
These statements have not been evaluated by the Food and Drug Administration. Our products are not intended to diagnose, treat, cure, or prevent any disease.
Refund Processing
Refunds are available only under:
- The 90-Day Satisfaction Guarantee.
- Verified damaged, defective, or incorrect products.
- Eligible unopened subscription renewals.
- The European Union cooling-off right.
Approved refunds are returned to your original payment method within 5–10 business days.
If you have not received your refund after 14 business days, please contact your bank before contacting us.
Please do not initiate a chargeback while your refund is being processed. Doing so can delay your refund by up to 75 days or more.
All requests are reviewed individually. Approval is never automatic or guaranteed.
Chargebacks & Payment Disputes
Please contact Thirmik before initiating a chargeback.
Starting a chargeback before contacting us:
- Voids eligibility for the 90-Day Satisfaction Guarantee.
- Voids eligibility for discretionary refund programs.
- May be considered a breach of our Terms of Sale.
We reserve the right to provide order records, IP data, delivery confirmation, and consent logs when responding to chargebacks.
European Union 14-Day Cooling-Off Period
Customers in the European Union may cancel or return unused products within 14 days of delivery, provided the product remains unopened and in its original condition.
Proof of purchase is required.
Holiday & Seasonal Shipping Delays
Orders are normally processed within 1–3 business days. During major holidays and peak periods, carrier delays may occur.
Refunds are not issued solely because a carrier delivered later than expected.
Fraud Prevention & Policy Abuse
We monitor claims for misuse of our refund and guarantee policies.
We reserve the right to refuse service, deny claims, or suspend accounts in cases involving:
- False non-delivery claims.
- False product defect claims.
- Duplicate or excessive refund requests.
- Inconsistent billing or shipping information.
- Repeatedly refusing or failing to claim packages.
- Abuse of promotional offers.
- Fraudulent chargebacks.
Limitation of Liability
To the maximum extent permitted by law, Thirmik is not liable for indirect, incidental, consequential, special, or punitive damages arising from the use or inability to use our products.
Our total liability shall never exceed the amount paid for the product giving rise to the claim.
All products are provided "as is", and individual results will vary.
Changes to This Policy
We may modify or update this policy at any time. Changes become effective immediately upon publication on our website.
Your continued use of our products or services constitutes acceptance of the updated policy.
