Zinc
Taking methyltestosterone increased the amount of zinc in the blood and hair of boys with short stature or growth retardation. It is not known whether this increase would occur in other people or whether zinc supplementation by people taking methyltestosterone would result in zinc toxicity. Until more is known, zinc supplementation should be combined with methyltestosterone therapy only under the supervision of a doctor.
Explanation Required
-
Andro supplementation has been shown to increase blood levels of testosterone in women, but not in men. No studies have investigated the possible additive effects of taking andro and methyltestosterone, but either increased drug effectiveness or more severe side effects are possible. Until more is known, these agents should be combined only under the supervision of a doctor.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
-
DHEA
DHEA (Dehydroepiandrosterone) supplementation has been shown to increase blood levels of testosterone, as does methyltestosterone. No studies have investigated the possible additive effects of taking DHEA and methyltestosterone, but either increased drug effectiveness or more severe side effects are possible. Until more is known, these agents should be combined only under the supervision of a doctor.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
