Frequencies ship from Canada. Due to the newly implemented tariff/duty from the US government on all imported items into the United States, additional fees do apply when ordering your Sludge. 

The new duty is 35% of the value and is shown on the checkout page. Yes, we are greatly annoyed by this new duty as well. This fee goes to the Federal government, not to us. 

Please note that delivery times for Sludge orders may be delayed due to the Canada Post rotating strike. We appreciate your understanding and patience during this time.

Liquid copper sulfate is a highly absorbable form of copper. 

Used in the production and function of enzymes in the body, it's an essential mineral. 

• The creation of collagen in the body is reliant on copper
• Copper affects the cartilage matrix
• Copper is needed for DAO production to process histamine in the gut
• Helps support tendon and ligament strength
• Great for topical fungal application

Each drop of this copper sulfate equals 1mg of coper sulfate.

Copper can cause nausea when taken orally, but it normally subsides after 10-15 minutes. Some people find their dose it's tolerated better in a glass of milk.

Copper sulfate can also be applied topically. Copper is anti-bacterial and anti-fungal. Topical use on fungal infections can speed recovery.
