Terms of Use
These terms govern use of EN Metabolism and explain the separation between this informational site and third-party merchants.
Informational Use
EN Metabolism provides general educational material about metabolism, coffee, caffeine, energy expenditure, weight management, ingredients and related research. Content is not individualized medical, nutritional, legal or financial advice and is not a substitute for professional assessment where one is appropriate.
You may use the site for lawful personal research. You should not use the site in a way that interferes with its operation, attempts unauthorized access, misrepresents its content or violates applicable law.
Affiliate Links and Commercial Relationship
Some links direct visitors to third-party merchant pages using an affiliate URL. If you purchase after following an affiliate link, the site may receive a commission without increasing the price solely because the link was used.
The presence of an affiliate relationship does not change the evidence standard used in the research sections. General evidence about coffee, caffeine or ingredients is not presented as direct proof of the finished product.
Product Orders Are Made With the Merchant
EN Metabolism does not itself sell, invoice, charge, dispatch or deliver Metabo Drops. Payment information and order details are entered on the merchant or its authorized checkout provider after you leave this site.
Any product availability, package configuration, price, taxes, currency conversion, payment method or checkout representation should be confirmed on the merchant page before purchase.
Shipping and Delivery
Shipping destinations, carriers, delivery estimates, charges and tracking arrangements are determined by the merchant or fulfillment provider. EN Metabolism does not guarantee a particular delivery time or shipping method.
Review the merchant's current shipping information before placing an order, especially for international destinations where customs, taxes or import rules may apply.
Returns, Refunds and Guarantees
Any return policy, refund period, money-back guarantee or eligibility condition is offered by the merchant, not by EN Metabolism. Merchant policies can change, so the controlling terms are the terms presented by the merchant when the order is placed or when a refund request is made.
EN Metabolism does not authorize refunds, receive returned merchandise or control the merchant's refund decision. Keep merchant receipts, order confirmations and transaction records if you may need support.
References, Research and Product Claims
Research references are provided to explain evidence relevant to coffee, caffeine, metabolism and ingredient categories. They should be read in context. A study on one ingredient, one dose or one population should not be treated as proof that a different product, dose or population will produce the same result.
Merchant representations about the product should be distinguished from independent research. Where the site discusses both, the context is intended to make that distinction clear.
No Individual Medical Advice
Supplement suitability depends on individual circumstances. People who are pregnant, sensitive to stimulants, taking medication or managing a health condition should obtain appropriate professional guidance before making decisions that could affect health.
If symptoms are persistent, severe, rapidly changing or unexplained, do not rely on a metabolism article or supplement page as a diagnosis.
Third-Party Sites and Services
External merchants, search engines, AI services and other linked resources are separate services with their own terms. EN Metabolism is not responsible for their uptime, content, privacy practices, checkout processing or policy changes.
