Unfortunately there is not much about increasing testosterone by way of supplements, unless you do believe what vendors tell you, of course.
Lets make clear an important and too often ignored point: it is not the same to rise testosterone levels beyond physiological levels (what athletes want, for example) and rise testosterone to normal levels if for some reason it is too low.
While the former it is impossible with supplements (if it was possible don't worry we already knew and steroid would be a thing of the past) the latter might be possible.
Go for fresh ginger (about 10g/day in an infusion) instead of an extract.
Go for zinc 30mg/day and magnesium as much as you can tolerate (much depends in which form it is, probably bisglycinate is best) instead of crappy ridiculously low dosage/high price/low quality ZMA.
Tribulus and DAA are very unlikely to do much more than depleting your wallet.
Pregnenolone might lead to more issues than benefits.
Onions have been proved to rise testosterone in low testosterone individuals.
Long Jack probably works but good quality is quite expensive and there are many fakes on the market.
Vitamin D3 (best coupled with K2) up to 5000IU/day.
Sting nettle root infusion (about 5g/day).
Chamomile.
Grapeseeds extract.
But more important than supplements are lifestyle changes:
A relatively high fat diet provides cholesterol which ensures plenty raw material for TRT production.
WEIGHT TRAINING.
Avoid long low intensity endurance training (jogging and such), high intensity interval training is a much better choice (you might give Tabata protocols a try).
Sleep at least 8-9 hours.
Avoid stress at all cost.
Meditation (in order to lower stress).
Lots of sex.
Avoid carbs more than once a day, best immediately after training.
Don't snack between meals.
Drink only water (no sodas etc...).
No more than 1 or 2 glasses of wine a day.
Aim to stay (or reach) below 15% body fat.
Well...the list is longer than that but lets start to fix some of the above...and I am sure there is plenty to work on already!
Oh,...and lets make it clear: if you are not willing to make changes in your lifestyle don't expect changes to happen!
Unlikely someone wants you to believe there are no magic fix all pills, especially without an high price to pay (not speaking about money here).
