[QUOTE="Jasen Bruce, post: 94193, member: 14"] Testosterone propionate is definitely not for everyone, however, there are certain men who do benefit from including the ester in their therapy. Propionate needs to be injected more frequently than cypionate, roughly every 2-3 days if used as a monotherapy to keep serum testosterone stable. For this reason and due to its more robust peak (and trough) effect I personally dont favor propionate as a monotherapy, but it does appear to have anecdotal benefit when combined with a longer ester including cypionate. Some men benefit from a more robust androgen peak, perhaps those suffering from finsateride syndrome or who have trouble with downstream testosterone conversion. Others who do not metabolize the cypionate ester consistently might also benefit from including lower dosages of shortened ester for faster onset and peak before leveling out. Again, this is all anecdotal, but it appears that the different effects noticed with a cypionate/propionate blend are experienced with twice per week injections (q3days). 50mg/mL is actually a high concentration of testosterone propionate since roughly 98% of the weight is actual testosterone rather than ester, and its rapid onset and metabolism utilize all of that testosterone over a shorter period of time, resulting in 50mg yielding a higher amount of T than usually produced endogenously. Usually, less is used as replacement therapy, 12.5mg - 25mg every 2-3 days is the replacement dosage I have seen many doctors start with. Of course, due to fluctuating levels across different patients, prop will need to be titrated more carefully if used as a monotherapy (and more frequent follow ups will be produced at the beginning to ensure levels are not fluctuating from a combination).
