Below is general information about the safety of the known ingredients contained in the product Extra Strength TestoJack 200. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately, short-term. American ginseng 100-3000 mg daily has been safely used for up to 12 weeks (1018,4225,4236,6461,9732,14804,19552,22367,22368)(22369,22370). Single doses up to 10 grams have also been safely used (6461,89404). A specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) has also been used safely for up to 64 months (11351,13192,14345,91275).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
A specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) in doses of 4.5-26 mg daily for 3 days has been used with apparent safety in children aged 3-12 years (22365).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Ginsenoside Rb1, an active constituent of American ginseng, has teratogenic effects in animal models (10447); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Eurycoma longifolia has been safely used in doses of 400 mg daily for up to 3 months and in doses of 200 mg daily for up to 9 months (17924,18138,93490,97312).
POSSIBLY UNSAFE ...when used orally in excessive amounts, long-term. There are some concerns about the safety of Eurycoma longifolia due to contamination with mercury and lead or adulteration with sildenafil (17925,17926,17927,18137,49087,93494). Some research shows that 36% and 17% of Eurycoma longifolia preparations from Malaysia contain high levels of mercury and lead, respectively (17925,17926,17927,49087). While safety issues related to these contaminants have not been reported in humans, taking high doses of Eurycoma longifolia long-term might cause symptoms of heavy metal poisoning or sildenafil-related adverse effects.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Animal research suggests that there are no negative effects of Eurycoma longifolia on the offspring (93493). However, research in humans is lacking.
LIKELY SAFE ...when maca is consumed in food amounts (9926).
POSSIBLY SAFE ...when used orally and appropriately, short term. Maca appears to be safe in doses up to 3 grams daily for 4 months (9928,10218,18289,90278,108603).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Taking muira puama 500-1050 mg daily, as part of a combination product, has been used with apparent safety for 1 month (63920,103224). There is insufficient reliable information available about the safety of muira puama when used long-term.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Extra Strength TestoJack 200. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking American ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, American ginseng use might interfere with immunosuppressive therapy.
Details
|
Theoretically, American ginseng can interfere with MAOI therapy.
Details
There is one case report of insomnia, headache, and tremors when an unspecified ginseng product was used with phenelzine (Nardil), an MAOI (617). There is also one case report of hypomania when an unspecified ginseng product was used with phenelzine (618). Theoretically, American ginseng may interfere with MAOI therapy.
|
American ginseng seems to decrease the effectiveness of warfarin therapy.
Details

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes (93489). This effect has not been reported in humans.
|
Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes (93489). This effect has not been reported in humans.
|
Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
Details
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes (93489). This effect has not been reported in humans.

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
Details
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism (17923). It is not known if separating administration will prevent this interaction.
|
Theoretically, Eurycoma longifolia may further increase levels of testosterone.
Details
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo (108451). It is unclear whether this increase would occur in individuals with normal testosterone levels.

Below is general information about the adverse effects of the known ingredients contained in the product Extra Strength TestoJack 200. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, Eurycoma longifolia seems to be well tolerated.
Most Common Adverse Effects:
Orally: None reported.
Endocrine ...Some research in both humans and animals suggests that Eurycoma longifolia might increase testosterone levels (17924). If testosterone levels are increased beyond the normal range, there is risk of testosterone-related side effects which could include acne, insulin resistance, hepatotoxicity, and others.
General ...Orally, no adverse effects have been reported with the medicinal use of maca. However, a thorough evaluation of safety outcomes has not been conducted.
Gastrointestinal ...Consumption of fresh, uncooked maca may cause stomach pain (40231).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
