What it is

How to use

• Use only as directed by a qualified healthcare professional. Follow prescription instructions and read the product label before use.
• Administration is by intramuscular injection. If you are not trained, do not self-administer—seek a healthcare provider or trained practitioner.
• Observe sterile technique: use a new, sterile needle and syringe for each injection and rotate injection sites to reduce tissue irritation.
• Dispose of used sharps safely in an approved sharps container.

Why it works

• Multi-ester formulation: combines fast-, intermediate- and long-acting esters to produce a staged increase in circulating testosterone.
• Rapid-onset component (propionate) provides earlier elevation of hormone levels after administration.
• Longer-acting component (decanoate) helps maintain elevated levels for an extended period between administrations.

What to expect

• Individual responses vary according to dose, baseline hormone status, health, diet and activity level.
• Some effects may be noticeable over days to weeks; the longer esters can remain active for several weeks after administration.
• Using exogenous testosterone can suppress natural hormone production; monitor under medical supervision.

Good to know

• Do not use if you are pregnant or breastfeeding. Seek medical advice if you have a history of prostate or breast cancer, cardiovascular disease, liver disease or other serious medical conditions.
• Stop use and consult a healthcare professional if you experience unexpected or severe reactions.
• Keep out of reach of children and pets.
