200-500mg is my recommendation. Some companies offer it in 110mg capsules, some are 115mg, some are 100mg. So it depends what brand you are using.
Spartan Nutrition's "4-Glory" is 115mg per capsules, 60 caps per bottle, putting it at the highest amount of 4-andro per bottle I've seen.
Primeval Lab's "4-Andro" is 100mg/60 caps.
Olympus Labs is 110mg/60 caps, or, 110mg/90 caps
I'd recommend you stack 4-andro with 1-andro. By itself it won't be too impressive. A recommended stack is 300+mg of both 1 and 4-andro, ran for 8 weeks. Common to include 500-700+mg of epiandro on that stack as well. SERM PCT afterwords
