I get tons of questions about what I think the best natural testosterone booster is. Based on the data, I will have to say it’s Ashwagandha. Very interesting study published last year about resistance training athletes supplementing with ashwagandha. 57 men between the ages 18-50 supplemented with 300mg 2x a day of KSM-66 ashwagandha(5% withanolides) or a placebo for 8 weeks and researchers tested for changes in muscle mass, body composition, and serum testosterone levels.

To sum up, researchers found a statistically significant difference in 1RM in bench press and leg extension, muscle size in arms, thighs, and chest, a decrease of 3.5% body fat(vs 1.5% placebo) and a 15% increase in total serum testosterone levels(vs 2.5% placebo). The average STARTING test levels were 630.45ng/dL, which is definitely not considered low. This is why I think ashwagandha is the best natural test boosting compound. Contra by @myoblox contains 600mg of KSM-66 ashwagandha(the one from this study) along with other ingredients to help metabolize estrogen.
