Yes there is a difference but not a huge one. Test Cyp has a 12 day half life where as Test E has a 10 day the reason for this is because Test C has an extra carbon atom attached to it making it weigh ever so slightly more. Some users have reported slightly extra water retention as a result with C as opposed to E. no clue as to why most choose E over C they are both equally as effective and provide pretty much the same result. Test Cyp seems to be used by more doctors for TRT patients for some reason...I have 3 relatives receiving TRT now all are on Test Cyp. One difference I have seen is Test Cyp comes in 200mg per ml form where as you never see Test E below 250mg per ml no clue why that is but that is just something I have noticed although I have seen some Test blends containing 200/200 of both Test E/C so there ya go
Selecting the type of treatment that is going to be best for your needs requires a doctor’s input into the subject. This can only occur after the completion of blood analysis because the hormone specialist will need to review these results along with the findings from a physical examination and medical history questionnaire to determine the best approach for each individual. There is no comparison when looking at testosterone enanthate or testosterone cypionate vs. testosterone propionate . The short-term effects of testosterone propionate make it a costly and often painful proposition for most men, and it is not as safe to use long-term as the other forms of treatment.
