Description
Project AD TauroTest
A testosterone support formula built around fenugreek, longjack (tongkat ali) and stinging nettle, taken as six capsules daily across three servings. 180 capsules, 30 days.
The three mechanisms, and what each is really doing
TauroTest attacks the problem from two directions, which is more coherent than most products in this category.
1. Raising production — fenugreek and longjack
- Fenugreek is proposed to act on luteinising hormone, which signals the Leydig cells in the testes to produce testosterone
- Longjack (tongkat ali) has the better evidence of the two, with results appearing most consistently in men who already have low baselines. Its active compound is eurycomanone, and the standardisation percentage matters far more than the milligram figure — see our Tongkat Ali page
2. Freeing what you already have — stinging nettle
This is the more interesting mechanism. Most of your testosterone is bound to sex hormone binding globulin (SHBG) and is biologically inactive while bound. Only free testosterone does anything.
3,4-divanillyltetrahydrofuran, from stinging nettle root, is proposed to bind SHBG competitively — displacing testosterone and increasing the free fraction without raising total production at all.
That is a genuinely different lever, and it explains why a product might improve how you feel without moving your total testosterone number much.
⚠ The 700% claim, honestly
Project AD's marketing states the formula can elevate luteinising hormone "up to 700% above baseline". You will see that figure repeated across the internet, so it deserves addressing.
What we would want you to know:
- Percentage changes in hormone markers can look dramatic while meaning little, particularly when the baseline is low. A large percentage rise from a small starting number is still a small number
- LH is a signalling hormone, not the outcome. What matters is whether testosterone actually rises and whether you notice anything — not what an intermediate marker did
- The figure traces back to ingredient marketing rather than to a trial on this finished formula
We are not saying the ingredients do nothing. Longjack in particular has reasonable human research. We are saying that a headline percentage is the least useful way to judge a product, and you should not buy on the strength of it.
⚠ The ceiling on this whole category
This applies to every natural testosterone product on any shelf, and it is the most useful thing we can tell you.
These ingredients correct suppression. They do not push levels above normal.
Longjack works most clearly in men who are already low. Fenugreek's effects are modest. Nettle frees what you already have rather than making more.
So if you are a healthy young man sleeping well, at a reasonable bodyweight, with adequate zinc and vitamin D — there is very little here to correct, and you should expect very little.
Our staff earn no commission. This is exactly the conversation we would have at the counter.
Get bloodwork first
Test total testosterone, free testosterone, SHBG and oestradiol.
SHBG is particularly relevant here, given that one of the three mechanisms targets it directly. If your total testosterone is fine but your SHBG is high, that is precisely the situation where a nettle-containing product has a plausible rationale. If your SHBG is already low, that lever has nothing to pull.
And if your testosterone is genuinely low, that is a medical conversation — low testosterone has causes worth identifying rather than supplementing around.
What moves testosterone more than any supplement
- Sleep. Testosterone is produced predominantly during sleep, and restricting it to five hours has been shown to substantially reduce daytime levels in healthy young men. This is the biggest lever there is
- Body fat. Adipose tissue contains aromatase, which converts testosterone to oestrogen
- Not dieting too aggressively. Severe deficits suppress testosterone
- Adequate dietary fat. Cholesterol is the raw material — very low fat diets are associated with lower testosterone
- Resistance training, and moderating alcohol
Specs
| Serving | 2 capsules, three times daily (6 per day) |
| Capsules | 180 — 30 days |
| Key ingredients | Fenugreek, longjack, stinging nettle |
| Type | Non-hormonal |
Six capsules daily is a substantial serving, and that is a consequence of dosing several botanicals properly rather than padding. Factor it into the cost per day.
How to take it
- Two capsules three times daily. On training days, take one serving an hour before training.
- On rest days, one dose morning and one afternoon.
- Always take one dose before bed, per the brand's directions.
- With food, since several ingredients absorb better with fat.
- Allow four weeks minimum, and eight to twelve before judging it on bloodwork.
Who this is for
- Men over about 35, where age-related decline makes a low baseline likelier
- Anyone whose bloodwork shows high SHBG with reasonable total testosterone — the clearest fit for this particular formula
- Men with confirmed low or low-normal testosterone, alongside medical advice
- Anyone who wants several properly dosed botanicals in one product
Who this is not for
Healthy young men with normal testosterone and normal SHBG. There is little to correct.
Anyone who has not had bloodwork. You will have no way to know whether it did anything — and SHBG in particular determines whether one of the three mechanisms is even relevant to you.
Anyone expecting anabolic-level results. Natural support and hormonal compounds are not comparable.
Anyone whose sleep, bodyweight or diet is poor. Fix those first — they are free and they work better.
⚠ Anyone allergic to peanuts or chickpeas — fenugreek is a legume in the same family, and cross-reactivity is documented.
Anyone with a hormone-sensitive condition, including prostate concerns, without speaking to a doctor.
Tested athletes should check the panel against their federation's list.
Not for anyone under 18, and not for women without medical guidance.
Stack it with: vitamin D, zinc and magnesium if not already covered — those three are the nutrients that genuinely suppress testosterone when low.
Frequently asked questions
How does it work?
Two ways — fenugreek and longjack aim to increase production, while stinging nettle is proposed to displace testosterone from SHBG, raising the free fraction without changing total output.
What about the 700% LH claim?
Percentage changes in hormone markers can look dramatic while meaning little, LH is a signalling hormone rather than the outcome, and the figure traces to ingredient marketing rather than a trial on this formula. Do not buy on the strength of it.
Will it raise my testosterone?
Only if something is currently suppressing it. These ingredients correct suppression rather than pushing levels above normal.
Why does SHBG matter?
Testosterone bound to SHBG is inactive. If your total is reasonable but SHBG is high, this formula has a plausible rationale. If SHBG is already low, that lever has nothing to pull — which is why bloodwork matters.
Why six capsules a day?
Dosing several botanicals properly takes space. Factor it into the cost per day.
How long before it works?
Four weeks minimum, eight to twelve before judging it on bloodwork.
Is there an allergy concern?
Yes — fenugreek is a legume related to peanuts and chickpeas, and cross-reactivity is documented.
What raises testosterone most?
Sleep, by a wide margin. Then body fat, not dieting too aggressively, adequate dietary fat, and resistance training.
