Short cycles will allow a much quicker HPTA recovery than a long cycle and this allows one to kepp a higher percentage of ones gains. In fact full testosterone rebound often happens in but a week. Gains often continue in the weeks after the short cycle is over simply because ones natural test production often jumps a little higher than normal becuase the pituitary really hammers out the LH and the testes have not shunk.
My natural test production is quite good for a man of 40, at 550. I tested my test level a week after I stopped a 14 day cycle and it had rebonded to 650 from the immediate pre cycle 550. On day 15 it was down to 54!
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes.
