Does cannabis tank testosterone? If so, how, and what natural supplements counter the effects? Info here.
My first and last drug deal happened in a grocery store parking lot. My friend was a marijuana "enthusiast," and she arranged the buy with her regular dealer. I was sweating bullets. The guy got in my car, money and weed exchanged hands, and it was over.
An hour later she went puff-puff, but I declined the pass. I'd tried marijuana before and didn't love the effect. Also, I'd heard that cannabis tanked testosterone levels. I didn't want that.
Today, in most places, all you have to do is walk into a retail store, present an ID, and buy your weed. It's as easy as buying beer, no shady parking lot deals required. That means more upright citizens are giving it a shot. They use it for fun, stress and anxiety relief, and as an alternative to harsh prescription drugs.
But the question remains: does marijuana reduce testosterone levels?
Weed and T: What We Know
For an informal meta-study, I dug up all the relevant research spanning the last five decades. The studies yielded mixed results.
One 1974 study observed that chronic marijuana users had significantly lower plasma testosterone levels compared to non-users. The decrease was dose-related – higher consumption correlated with greater reductions in testosterone.
However, in a 2021 prospective analysis, researchers found no significant differences in T levels between marijuana users and non-users. The study concluded that pot use didn't have a substantial impact on male reproductive hormones.
Likewise, other studies suggest that acute use of THC (the psychoactive compound in marijuana) may lead to a temporary decrease in testosterone. However, these effects are usually mild and transient – T levels return to normal after the effects of THC wear off.
Some studies also suggest that long-term heavy use may be associated with slightly lower testosterone levels, while others find no significant long-term impact. Any changes tend to be modest and unlikely to cause clinical hypogonadism in most men.
Then there are all the confounding factors. Does a chronic weed smoker have other habits that affect his hormones? Is he a drinker, too? Does he work out?
Testosterone aside, there's stronger evidence that weed can negatively affect sperm count, motility, and morphology, potentially impairing fertility. A 2015 study found that smoking ganga more than once per week was associated with low sperm count. But weirdly, the same study showed that their testosterone levels were fine, even on the higher side.
So, does weed lower T? Maybe. It seems to reduce levels while you're high, but then they pop back up. A heavy daily user, referred to as a "total pothead" in the literature, might have slightly lower T levels, but mainly because he's stoned all damn day.
How Could Marijuana Lower T?
If weed lowers testosterone, even just temporarily, how does it do it? Well, THC seems to influence the hypothalamic-pituitary-gonadal (HPG) axis in men, suppressing the production of luteinizing hormone (LH), which stimulates testosterone production. (A related hormonal effect may occur in women via the hypothalamic-pituitary-ovarian or HPO axis.)
How to Fight Any T-Dropping Effects
If you're going to partake, you mainly want to thwart the effects on LH production, along with staying topped off in certain vitamins and minerals that support LH. Here's how to do it:
1. Take Longjack
Longjack (Tongkat Ali or Eurycoma longifolia) enhances the HPG axis by stimulating the gonadotropin-releasing hormone (GnRH), which signals the pituitary to produce more LH. It also reduces cortisol which indirectly supports testosterone and LH production.
Usage: Take 300 mg using standardized LJ100 formulated with Labrasol (an agent used by the pharmaceutical industry to increase bioavailability). That's one softgel daily using Omega-Man High Absorption Longjack (Buy at Amazon).
2. Try Resveratrol
Resveratrol acts as an aromatase inhibitor, reducing estrogen conversion and signaling the hypothalamus to increase GnRH and LH production. It also improves the sensitivity of LH receptors in Leydig cells.
Usage: Take 600 mg daily: two softgels of Rez-V High Absorption Resveratrol (Buy at Amazon). Rez-V uses active trans-resveratrol and a specialized delivery system to increase absorption.
3. Top Off Your Vitamin D and Zinc
The idea here is to make sure you're not already lacking in these two nutrients. You don't want to add a vitamin or mineral deficiency to marijuana usage.
Adequate vitamin D levels are strongly linked to improved testosterone and LH production. It optimizes testosterone and LH by enhancing GnRH secretion and pituitary response. Make sure your blood levels of vitamin D are in the high-normal range by taking the microencapsulated form. D Fix High Absorption Vitamin D (Buy at Amazon) contains 5000 IU.
Zinc deficiency is also linked to suppressed testosterone and LH levels. Supplementation restores LH by supporting overall reproductive hormone balance. Take 30 mg daily using the chelated form. That dosage is part of the Elitepro Vital Minerals (Buy at Amazon) formula.
