Lasix is probably one of the most dangerous drugs some pre-contest bodybuilders used. Even the IFBB tests for diuretics, and that is saying something Lasix was used to excrete excess water during the last day or two before a show. This was said to be especially effective with subcutaneous water (under the skin) so a “ripped to the bone, dry, and hard” look was achieved. Lasix was also used by some to lose weight for weight class oriented sports. Loop diuretics work by increasing the excretion of electrolytes (sodium, chloride, potassium) which the body normally uses to maintain intra cellular and extracellular water. Monitoring of the re-absorption of potassium, sodium, and chloride ions during use should have been a must, but few did so. Lasix can and has caused death. As to dosages, it depended upon the effect achieved. Normally 20-40-mg was taken and (over a periods of 2-4 hours) the bodybuilder evaluates the results. This was followed once or twice more at 4 hour intervals if more water loss was necessary. Too much water loss makes the body appear flat with no vascularity and makes it impossible to pump-up before walking out onto the stage. The effects of Lasix begin within about an hour of administration and continue for 6-8 hours. Once “the look” was achieved, it was unnecessary to ingest more to maintain “the look”.

Lasix is very strong and was reported to cause diarrhea, dehydration, dizziness, muscle cramps, circulatory disorders, vomiting, circulatory collapse, fainting, and cardiac arrest. It was considered far more safe to start with 20-mg and repeat every 4 hours than to use higher dosages for a shorter period of tome. Over 40-mg per dosage increased side effects dramatically!
