Does anyone here find intraworkouts useful when bulking as or only dieting?
It depends on the profile. If someone was using BCAAs only it would perhaps be more pertinent when in a caloric deficit.
With something like iForce Compete the carnitines can be used in either situation and with Amino IV the lemon verbena could be used in either situation.
It is a good question but impossible to answer without naming a specific product.
