The best-disclosed clean single-herb horny goat weed — 40% icariins, third-party tested.
- Berberine
Toniiq Ultra Berberine HCl 1500mg
Berberine bottle audit — purity, dose accuracy, GI side-effect ramp, and the metformin drug-interaction warning.
- Ashwagandha
Toniiq Ultra High Strength KSM-66 Ashwagandha
Eight weeks on the highest standardised KSM-66 on Amazon — 10% withanolides UHP. What 2x the standard concentration buys vs. the trial-grade 5%.
- L-Theanine

The least-unverified pick — strongest testing claim, highest standardization, fair price.

Transparent Labs BULK Pre-Workout
The clinically-dosed, fully-disclosed benchmark — dosed to the milligram, no proprietary blends.
- Creatine
Transparent Labs Creatine HMB
Creapure monohydrate + 2g HMB per scoop — where the HMB addition pays off (untrained) vs. doesn't (trained lifters per Wilson 2013).
- Protein Powder
Transparent Labs Grass-Fed Whey Protein Isolate
The highest protein density here, with a genuinely clean grass-fed label.
- NMN
Tru Niagen Nicotinamide Riboside (NR) 300mg
The stable, best-studied NAD+ precursor — clearly NR, not NMN.

- Electrolyte Powder
Ultima Replenisher Daily Electrolyte — Original Variety Pack
The sugar-free, magnesium-forward pick — minerals without the salt load.

EPA/DHA-per-dollar review — purity, oxidation, and how the bottle compares against the trial-dose ranges from the literature.
- Cistanche
WIXAR Naturals Cistanche Tubulosa (50% Echinacoside)
The 50% standardization spec at a value price — same active number, thinner paperwork.
