A practical guide to evaluating UK testosterone supplements: which doses matter, what to skip, and how to read a label.
Why most UK 'test boosters' are underdosed
The supplement industry has been selling 50mg sprinkles of tongkat ali under premium labels for two decades. The clinical research uses 200-600mg of standardized 200:1 extract. The brands using the research dose are the only ones worth your money.
What ingredients actually have human trial data
Tongkat ali (Eurycoma longifolia 200:1), fadogia agrestis 10:1, KSM-66 ashwagandha, vitamin D3 at 5,000 IU, zinc, boron. That's the short list. Tribulus terrestris hasn't held up in well-designed human trials. D-aspartic acid results have been mixed.
Dose thresholds that matter
Tongkat ali: at least 200mg of 200:1 extract, ideally 400-600mg. Fadogia: at least 300mg 10:1, ideally 600mg. Ashwagandha: 300-600mg of KSM-66 specifically. D3: 5,000 IU is the dose that consistently moves serum levels.
Red flags to skip
Proprietary blends (means doses are hidden, usually because they're tiny). 'Maximum strength' claims without disclosed mg amounts. Tribulus listed as primary active. D3 at 1,000 IU. Any 'test booster' priced under £15 a month.
What ANABULL did differently
We dose every ingredient at the clinical research level, list every milligram on the label, and run no proprietary blends. The Stampede stack adds vascular support (3000mg L-citrulline) and cycle support (TUDCA + DIM + NAC) for guys running protocols longer than 4 weeks.
