Sustanon 250« is an oil-based injectable testosterone blend, developed by the international drug firm Organon. It typically contains four different testosterone esters: testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg). An intelligently "engineered" testosterone, Sustanon is designed to provide a fast yet extended release of testosterone. The propionate and phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks (respectively). This is a big improvement from standard testosterones such as cypionate or enanthate, which provide a much shorter duration of activity, and a more variable blood level. A slightly shorter acting Sustanon 100, which uses only three esters, is also made by Organon in certain areas (see: Sustanon 100).

As with all testosterone products, Sustanon is a strong anabolic with pronounced androgenic activity. It is most commonly used as a bulking drug, providing exceptional gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of testosterone, this injectable is noted as being slightly more tolerable than cypionate or enanthate. As stated throughout this book, such observations are only issues of timing however. With Sustanon, blood levels of testosterone are building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, testosterone will break down equally without regard to ester. Many individuals may likewise find it necessary to use an anti-estrogen, in which case a low dosage of Nolvadex«(tamoxifen citrate) or Proviron«(mesterolone) would be appropriate. Also correlating with estrogen, water retention should be noticeable with Sustanon. This is not desirable when the athlete is looking to maintain a quality look to the physique, so this is certainly not an idea drug for contest preparation.
Being a strong androgen, we can expect the typical side effects. This includes oily skin, acne body/facial hair growth and premature balding. The addition of Proscar«/Propecia« should be able to minimize such side effects, as it will limit the testosterone to DHT (dihydrotestosterone) conversion process. Sustanon will also suppress natural testosterone production rather quickly. The use of HCG (human chorionic gonadotropin) and/or Clomid« (clomiphene citrate)/Nolvadex« (tamoxifen citrate) may be necessary at the conclusion of a cycle in order to avoid a hormonal crash. Remember though, Sustanon will remain active in the body for up to a month after your last injection was given. Beginning you ancillary drug therapy immediately after the steroid has been discontinued will not be very effective. Instead, HCG or Clomid«/Nolvadex« should be delayed two or three weeks, until you are near the point where blood androgen levels are dropping significantly.
Although Sustanon remains active in the body for approximately three weeks, injections are taken at least every 10 days. An effective dosage ranges from 250mg (one ampule) every 10 days, to 1000mg (four ampules) weekly. Some athletes do use more extreme dosages of this steroid, but this is really not a recommended practice. When the dosage rises above 750-1000mg per week, increased side effects will no doubt be outweighing additional benefits. Basically you will receive a poor return on your investment, which with Sustanon can be substantial. Instead of taking unnecessarily large amounts, athletes interested in rapid size and strength will usually opt to addition another compound. For this purpose we find that Sustanon stacks extremely well with the potent orals Anadrol 50« (oxymetholone) and Dianabol (methandrostenolone). On the other hand, Sustanon may work better with trenbolone or Winstrol« (stanozolol) if the athlete were seeking to maintain a harder, more defined look to his physique.
Sustanon 250 is probably the most sought after injectable testosterone. I must, however, emphasize that this is not due to an unusual potency of this testosterone combination (remember esters only effect the release of testosterone), but simply because a "stack" of four different esters is a very good selling point. To the na´ve customer it "must" be better; after all, there are four different steroids in there, not just one! But the reality is that in most instances you will get a whole lot more for your money with testosterone enanthate or cypionate. The advantages to be found in Sustanon are for the medical user only. If you tied to your doctor for regular injections, than Sustanon would allow you to visit the doctor on maybe a monthly basis, whereas you would need to fork up the cash and time for an office visit every two weeks with one of the other esters. This equates to a clear and dramatic improvement in patient comfort. But if you are a bodybuilder injecting the drug every week anyway, there is simply no advantage to be found in Sustanon at all. Blood levels will build to the same extremes either way. Don't let the fancy stack fool you - Sustanon is just overpriced testosterone.

Despite being much more costly than other esters, Sustanon remains very abundant on the U.S. black market. In fact, the high demand for this steroid has stirred new interest in its manufacture, particularly by veterinary companies in Mexico. As a result, we now have a lot more than the Organon brand name to choose from.
Quality Vet introduced a Sustanon clone to the Mexican market last year, called 4 Test. It contains 250mg/ml of steroid like the original Organon product, and the correct ratio (30:60:60:100) of esters. It comes in a 5ml multi-dose vial. Be sure to look for the Quality Vet security hologram when shopping.

Ttokkyo is no longer in business, and old lots of its Testonon 250 should be long gone now. Avoid any product with a Ttokkyo label, as it will most certainly be a fake.

Pet's Pharma recently introduced a Sustanon 250 clone to Mexico as well. The product is called Test 250, and carries the normal Sustanon 250 formula in a 10ml multi-dose vial. This item should be a very cost effective alternative to Mexican pre-loads, albeit in the package of a veterinary product (for some the greater scrutiny placed on human medicines in Mexico makes the Organon product worth spending the extra money on).
Loeffler's Testosterona IV L/A is still around, which contains the same steroid blend in a 10ml vial. Lab tests on Loeffler's Reforvit-B and testosterone propionate did not fair well during the publication of Anabolics 2004, so I can't make any guarantee about the quality of this product. Be sure to look for their hologram security sticker when shopping.
Tornel makes a version of this steroid called Supertest-250. This Mexican vet firm has a long-standing reputation as a fair quality company. It always seems to deliver a good dose of steroid, but by most accounts it is typically a little less than what is listed on the label. Tornel is usually a cheaper product than most competitive brands, so it may still be a better deal even with modest underdosing.
Norvet makes Testo-Jet LA in Mexico, which is another 10ml veterinary product. This is a new lab on the steroid scene, although they have a long history of making other vet drugs. Currently the line is not very popular, but will likely catch on if their quality is good.
Intervet, makers of Laurabolin, manufactures a 5ml vial in Australia called Durateston. Don't expect it to circulate the black market very much though, as these drugs are tightly controlled in Australia these days.
BM Pharmaceuticals is a quasi-legit company in India producing Sustaretard 250. This product comes in the form of 1ml ampules, each containing (obviously) the 250mg blend of esters. This product is very reminiscent of Russian Sustanon by Infar (see below) in its packaging (see pictures in the photo section)
Russian Sustanon, manufactured under license by Infar in India (for export to former Soviet countries), may still be in circulation. This product comes packaged in plastic strips that hold five ampules, sealed on the face with white paper label. Each ampule is enclosed in a separate compartment, and the packaging is scored so as to break off individual ampule sections. One standout characteristic is that the ampule labels and packaging bear a big green "250" imprint under the lettering.
Organon Sustanon is marketed directly in Russia now. The product looks very much like European forms of Sustanon, with clear glass ampules, colored bands, and paper labels. Note that the product name is written in Cyrillic as "CYCTAHOH".
Sostenon 250 redi-jects manufactured by Organon in Mexico are also still found, although much less commonly in recent years in light of the less expensive products now coming out of this country. The price for a Sostenon redi-ject is about $7-8 in Mexico, $10 in some more expensive tourist areas. In the United States they can sell for as high as $25 each. Note that even though Organon never had any problems with counterfeit redi-jects, they still decided to update their packaging recently with a new security feature. Specifically, they have embedded watermarks of the Organon logo all around the surface of the box. This is a difficult trait to copy without spending quite a bit of money, although probably unnecessary given that the syringes and foil sealed trays are already too costly for underground labs to consider duplicating. If you want a guaranteed safe buy, the Mexican "Pre-load" has always been one.
Less common, but still seen on the US black market, are the European versions of Sustanon from countries like Italy, Portugal, Belgium, and England. All of these products use ampules that are scored, carry colored (yellow and red) rings on the tip, and have white paper labels.
Durateston, the brand name Organon uses to market this multi-component testosterone blend in Brazil, is also seen in the U.S. on occasion. Be sure your product has the accompanying box and paperwork, which will weed out some of the cheaper counterfeits.
Two versions of this steroid have been made in Egypt by the Nile Co in recent years. The first is called Testonon, and the second Sustanon. The fact that two different versions exist may have to do with licensing issues with Organon, as only the latter product is seen to bear the Organon logo. Fakes are known to exist, so be careful when shopping. In particular, make sure the Nile logo is genuine on the box (both products), which will help you identify one of the most common fakes in circulation at this time (see photo section for comparison photographs). Also, the Nile Sustanon is highly counterfeited, but there are a couple of things you can look for to weed out most of them. For one, make sure the "/" in "250mg / ML" touches or almost touches the Organon logo. Many of the fakes have a larger than normal space here. Also, look at the letter "X" in "Exp." closely. The real product doesn't really have a normal "Western" letter X. The two halves of the letter do not intersect perfectly in the middle, and the letter actually looks more like a K or N upon close examination. Fakes are normally printed with the help of Western computer equipment with more familiar typestyles. If your X looks like a perfect X, the product you have is fake.
Sustanon 250 from Karachi Pakistan is also popular as of late. These ampules are clear glass with yellow silk-screen printing. This is one of the few versions of this steroid product sold by Organon globally that does not carry a paper label. Fakes are circulating in high volume at this time, so be careful. Note that the current real product has its lot numbers printed on with electronic equipment, and are not silk-screened on the glass at the same time as the rest of the lettering.
Organon also sells Sustanon in Indonesia without a paper label. The product comes in a clear class ampule, carrying simple dark brown silkscreen printing directly on the surface of the glass.
