there was a time when 4 grams of citrulline was huge. I agree it’s less than what most offer now but I still think it’s plenty to get a good pump. Especially with all the glycerine. Would I buy this stuff? Not unless it was cheap. Would I take it as a gift and use it like the OPs situation? For sure. So my opinion on it is that for a gift, not great, but not too shabby and definitely worse out these
