Test-P injections are made as a rule every day or every other day. Steroid cycle lasts 6-8 weeks. Testosterone enanthate and cypionate cycles shall be run not less than for 10 weeks. On shorter cycles long esters will not be able to expose their full potential. For enanthate and cypionate is one injection every 5-7 days is enough. However, some athletes prefer more frequent injections in order to provide more even hormone level in blood and to avoid dramatic fluctuations. And don`t forget, that steroid aromatizes very easily to estradiol. Independent on the compound you use, keep your estradiol under control by taking aromatase inhibitors (anastrozole preferably). Antiestrogens (SERMs) are in this context not recommended, because they will reduce the cycle efficiency.
