While both androsterone and epiandrosterone may be used as a capsule, androsterone may be more powerful when used as a sublingual (where it is absorbed through the tissues under the tongue directly into the blood stream) and epiandrosterone looks promising to use as a transdermal (where it is applied to and absorbed through the skin). For this reason, androsterone products are often sold as a lozenge to be dissolved slowly in the mouth. The typical dosage range for androsterone is 300-400 mg/day, though some may dose higher. This is best used in 4-6 week cycles, with a mild over the counter post-cycle therapy to follow such as an all-in-one test booster and estrogen blocker, of which there are many to choose from.
A European review describes cases of allergic reactions , including bronchospasm and anaphylaxis, in patients allergic to cows milk proteins receiving injectable methylprednisolone products containing lactose of bovine origin. In most cases, the patients were younger than 12 years old and had childhood asthma . In some cases, the reaction was mistaken as lack of efficacy, and additional doses of were give with subsequent worsening of the patients condition. The European Union has recommended lactose-containing methylprednisolone products be reformulated to remove any trace of milk proteins by 2019. [ Ref ]
