Testosterone esters were synthesized for the first time in 1936, and were found to have greatly improved potency relative to testosterone.  Among the esters synthesized, testosterone propionate was the most potent, and for this reason, was selected for further development, subsequently being marketed.  Testosterone propionate was introduced in 1937 by Schering AG in Germany under the brand name Testoviron.  It was the first ester of testosterone to be introduced,  and was the major form of testosterone used medically before 1960.  In the 1950s, longer-acting testosterone esters like testosterone enanthate and testosterone cypionate were introduced and superseded testosterone propionate.  Although rarely used nowadays due to its short duration,  testosterone propionate remains medically available. 
A Testosterone Propionate cycle during a cutting phase is an excellent way to ensure muscle mass isn’t lost during a diet. You will also find it enhances fat loss efficiency and produces a stronger more defined look. As with the off-season Testosterone Propionate cycle, the total stack and doses may need to be adjusted in order to meet your needs; again, this is a sample guide. It is also important you consult with your doctor to ensure you’re healthy enough for use. Important Note – This type of Testosterone Propionate cycle will not produce less or more water retention compared to plans that might contain Testosterone Cypionate or Testosterone Enanthate in the Propionate versions place. It’s often assumed by many steroid users that Testosterone Propionate will yield less water retention than the aforementioned versions but that’s a myth. Testosterone is testosterone and does not become active in the body until the ester has been removed. The reason many believe it leads to less water retention is a very simple one; most given extra attention to their diet and estrogen control during a cutting phase, and this will always lead to less water retention in a Testosterone Propionate cycle or any cycle.
