Esiclene was not an anabolic steroid in the conventional sense. The drug was injected directly into a lagging (smaller muscles such as biceps, triceps, calves and delts, usually respond best) body part during the last 7-15 days before a contest.
Though Esiclene is anabolic it is the drugs distinct site specific inflammatory /tissue fluid accumulatory effects users pursued. When an injection is administered, the muscle responds by receiving fluid from the lymph system as an inflammatory response. Within 1-2 weeks arm sizes were reported to increase in size by as much as 1.5 inches. This effect was quite temporary as inflammation began to decrease within about 24 hours. Since 20-mg of lidocaine was contained in each vial, the swelling effect it is not a surprise that the injections were not as painful as one may think. Usually a bodybuilder would inject 1-ml into each of 1-2 lagging body parts daily for 4-7 days, then increase to 2-ml per muscle for and additional 3-7 days. Some reported an improved muscle hardness over the whole body during use.
