Sustanon 250 Profile

By Leigh Penman


This is part of a continuing series provided exclusively by MuscleSport Mag giving information on a variety of performance-enhancing drugs for educational purposes. While it is apparent that people are going to use these substances regardless of the health and legal risks involved, quality information is necessary and learning as much about them as possible can only assist an adult making a decision either way.


(Testosterone blend: 30mg Testosterone Propionate, 60mg Testosterone Phenylpropionate, 60mg Testosterone Isocaproate, 100mg Testosterone Decanoate)

Sustanon 250 is an oil based injectable testosterone blend. Its popularity lies in the fact that it presents the user with a blend of four different testosterone esters: Propionate, Phenylpropionate, Isocaproate and Decanoate. This allows for a fast yet sustained release of testosterone which stays active in the system for around three weeks.

The Propionate and Phenylpropionate esters are the first to be released in the system and take effect within the first four days, whilst the Isocaproate and Decanoate remain active for two to three weeks respectively. This supplies the user with the obvious advantage of more sustained testosterone levels throughout its active life – unlike the shorter activity of other testosterone products. However, despite this fact, some athletes choose to inject Sustenon at a dose of 250mg every seven to ten days. As with all drugs, higher doses have been reported with some using 750-1000mg/week but this is not advisable since side effects are likely to increase hand in hand with dosage.

Talking of side effects, you can expect all the usual testosterone related ‘suspects’ to manifest e.g. oily skin, body/facial hair growth, premature balding and elevated estrogen levels which can also produce noticeable water retention. However, due to its slow and sustained release, Sustanon 250 does seem to aromatize (convert to estrogen) at a lower rate than other testosterones. There are always going to be some individuals who are more susceptible to estrogen conversion than others and therefore the addition of an anti-estrogen such as Nolvadex may be necessary.

Sustenon will also suppress natural testosterone production so it may also be necessary to add HCG (Human Chorionic Gonadotropin) and/or Clomid (Clomiphene Citrate) at the conclusion of your cycle in order to avoid a hormonal crash. Keep in mind the fact that Sustenon will remain active in the body for up to a month after your last injection, therefore HCG or Clomid use should be delayed by two or three weeks until your blood androgen levels begin to display a significant decline.

STACKING TIPS: Athletes whose focus is gaining size and strength should find that adding orals such as Anadrol 50 or Dianabol produces the desired result.
Meanwhile, those seeking a harder, more defined, look should look to Trenbolone or Winstrol as a supplementary drug.

Leigh Penman, in addition to be a staff writer at MuscleSport Mag, has been writing for bodybuilding magazines, websites and nutritional supplement companies since 1985. Whilst residing in the UK, she earned the reputation of being one of the top female writers in bodybuilding-related media. Her credits included being a contributing editor on all the magazines in production as well as filling the shoes of Ladies Editor and Showbiz Editor on two publications (the later being on Arnold’s sanctioned magazine, ‘Bodypower’). During this time she also competed successfully on four occasions (placing in the top four in all contests).

Relocating to New York in the late 1990s she focused her writing attention to crystal healing techniques and metaphysics – however, she still maintained a five day workout schedule during this time and gained her personal training certificate.

Having also studied pharmacology in relation to sports performance, her writing began taking her in that direction until the present day which sees her embarking on a return to the magazine world, as well as extending her web-related work in the bodybuilding and fitness field.



Leigh has been working out for close to thirty years so she is clearly a writer who ‘walks her talk.’
