Test Booster

Increase endogenous systemic and intratesticular testosterone in hypogonadal men. Testosterone may support improved muscle mass and strength, libido, energy level and mood and cognition.

• Preserve sperm count and fertility in men with fertility aspirations.
• Compared to exogenous testosterone, Test Booster will not lead to testicular atrophy.

Potential Side Effects

• Headache and nausea
• Nausea
• Visual disturbances (blurring)
• Estrogenic side effects such as gynecomastia, bloating or mood swings
• Joint pain, back pain, bone pain, osteoporosis, fatigue, skin rashes, depression (from anastrozole)

Clomiphene is a Selective Estrogen Receptor Modulator (SERM). Clomiphene antagonizes estrogen in the hypothalamic-pituitary-gonadal axis to induce Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH). LH stimulates the Leydig cells to produce testosterone. The resulting high intratesticular testosterone supports spermatogenesis. FSH works synergistically with LH, acting on the Sertoli cells of the testes and play a role in spermatogenesis, sperm maturation, and sperm quality. DHEA and progesterone play a supporting role in testosterone synthesis. DHEA and 7-Keto DHEA may also contribute to improved mood, energy levels and body composition. Anastrozole is a non-steroidal aromatase inhibitor which suppresses estrogen synthesis and helps to counter the estrogenic side effects of clomiphene.

Q. Strive offers Test Booster with or without anastrozole. Which version is for me?

A. Some of the increased testosterone induced by Test Booster therapy invariably gets converted into estrogen. For the most part, this is desirable. When testosterone and estrogen increase in tandem, it may amplify anabolic and libido effects. The increase in estrogen may also have cardioprotective and neuroprotective effects, improve bone mineral density and body composition, and enhance mood and cognition. However, some men, especially if obese, may have high aromatase activity that results in excessive estrogenic effects, such as fluid retention and breast tenderness. Your provider, after assessing testosterone:estrogen ratio and severity of symptoms, may consider bringing anastrozole on board to counter these side effects.^6,7,8

IMPORTANT INFORMATION ABOUT COMPOUNDED MEDICATIONS

This medication has been compounded (custom-prepared) by a pharmacy. Compounded medications are specially prepared for individual patient needs based on a valid prescription and, as such, are not reviewed or approved by the U.S. Food and Drug Administration (FDA) for safety or efficacy. These statements have not been evaluated by the FDA.

This compounded preparation:

• Has not been approved by the FDA
• Has not undergone FDA review for safety, effectiveness, or quality
• Is prepared specifically for you based on your prescriber's order
• Individual outcomes may vary

Dosing is determined by the prescribing provider based on patient-specific factors. Always follow your healthcare provider's instructions. Compounded medications are not subject to FDA approval and lack the same safety and efficacy data as FDA-approved commercial medications. This medication should be prescribed and monitored by a licensed healthcare professional familiar with the condition being addressed and the specific applications of the medication.
