For customers of our official online store, we guarantee "100% effective or free".

100% effective or free

If you are not satisfied and STREPTOkill does not help to solve your problem, please return the product to our logistics center---ELMS service s.r.o., Budova B6, Ve žlíbku 1800/77, Praha 9 - Horní Počernice, PSČ 193 00---within 30 days of purchase to recieve a full refund. 

Many of our customers buy 3 packs of Streptokill in order to take advantage of our buy-2-get-1-free promotion. This promotion is also covered by the guarantee of "100% effective or free", but please note that only 1 of the 3 returned packs, should you return them, may be unsealed or partially-used. The other Streptokills must be unsealed;  the 100% money-back guarantee applies to no more than one unsealed pack.

From our experience, Streptokill helps the vast majority of people and fewer than 1% of our customers have use the return-policy guarantee. We firmly believe that you will join the 99% of patients for whom Streptokill yielded significant results, and we look forward to having you among our satisfied customers.
