What is uncertain
Read off the same rows as above. Nothing here is added that the entry does not itself record.
- Thin evidence: Lean mass / strength (grade C).
The evidence in words
The verdict
For lean mass / strength, Phosphatidic Acid earns evidence grade C (small effect, low consistency) — the evidence is limited or mixed. Few small trials
How it might work
It activates mTOR, the central regulator of muscle-protein synthesis, in response to mechanical load.
How to use it
750 mg/day (often split), around training.
Safety & cautions
Appears safe; limited long-term data.
Bottom line
A plausible muscle-growth aid with only a few supporting studies. Modest at best; not a priority over protein and creatine.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- 750 mg/day with training.
