Top outcomes
18.75-56.25 mg daily of a standardized CO2 extract (the cited trial gave 6.24, 18.75 or 56.25 mg a day in three doses, found no effect overall, and only a subgroup on 18.75 mg a day had fewer attacks). Leaf and extract products are labelled at 100-300 mg daily, standardized to at least 0.2-0.7% parthenolide, above the highest dose in the cited trial.

A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength
British Journal of Sports Medicine (2018) · Meta analysis · n=1863
49 RCTs, 1863 participants: protein supplementation increased 1RM strength (2.49 kg), fat-free mass (0.30 kg) and muscle fibre cross-sectional area during prolonged resistance training.
The points come from one dose-comparison RCT in 48 resistance-trained young men, who took 0, 10, 20 or 40 g of whey protein isolate straight after leg exercise, three hours after a high-protein breakfast (PMID 24257722). Over the next four hours myofibrillar muscle protein synthesis rose 49% above 0 g with 20 g and 56% with 40 g, and 10 g gave no added stimulation. The authors conclude 20 g is enough for the maximal response in about 80 kg men, and 40 g mainly raised amino acid oxidation and urea production. This is an acute measure of protein synthesis, not muscle growth over weeks of training, and the trial did not report tolerability, so no ceiling dose is set.
