To find out, I'll be eating 4 POUNDS of them, every week, for the next 10 weeks to see if they contribute to the next testosterone blood draw the 3rd week of June!
The benefits I've found so far:
- They're delicious!
- If you have a sweet tooth like I do, they help to satisfy that desire.
- Eating 4 Pounds over one week is pretty easy when divided into pre-portioned containers:
According to the research I've done, the skins of red grapes 🍇 contain resveratrol.
Resveratrol is an aromatase inhibitor.
Aromatase is an enzyme which breaks down testosterone into estrogen.
Inhibit aromatase, preserve testosterone, therefore higher maintained testosterone levels.
The question is, how much resveratrol is needed, and how much resveratrol is there in grapes?
4 Pounds of grapes a week seems reasonable to me...
I suppose a separate study could be performed utilizing JUST red grapes...
Summer's just around the corner though; so let's find out if eating 40 Pounds of red grapes in ten weeks, along with the other foods and supplements I'm using, will raise testosterone!
To see the other measures I'm taking in this personal study, and see the results, follow 
Testosterone levels were 428 and 437, measured for a baseline in November and February, let's see what happens in June!
