Sustanon 250 (testosterone blend): Sustanon 250, the popular multi-component testosterone, can be found in all corners of the black market. It is produced in a number of countries and is in high demand among athletes. Counterfeit marketers have been cashing in, so take caution. Here are some guidelines when looking to purchase this. For starters, the Nile Co. Sustanon from Egypt and Sustanon 250 from Pakistan are the only versions we have seen which bear silk-screen lettering directly on the ampule glass. All other legit ampules of Sustanon will have a paper label. Many fakes are circulating with silk-screening, so look out for these. Also, Sustanon is only produced in 1ml ampules and redi-ject syringes (Mexico only). Never purchase a multi-dose vial with a Sustanon label. The Mexican redi-ject syringe is a safe buy, but we have been hearing stories of underdosed product circulating. At this time the problem seems isolated. There is also a popular copy of the Infar product from India, which has a paper label. It can be identified by noticing the rounded corners on the label, as the real Infar item is squared at the edges. Durateston: This south American version of Sustanon has become popular as of late. The ampules contain blue silk-screen writing on the surface of glass. At this point fakes do not appear to be a problem. Omnadren 250: This is a multi-component testosterone very similar to Sustanon. Legit ampules bear black or red silk-screen directly on the glass, which is easy to remove with your thumb. Currently fakes do not seem to be a problem. The Freezer Test: For a quick test, drop an ampule or redi-ject into your freezer. 250mg is very close to the limit 1ml of oil will hold in suspension. Once in the freezer, the temperature of the oil will drop reducing the total amount of steroid which can be dissolved. Quickly, you will notice the oil cloud up. This is the steroid precipitating out of the solution. If the oil in your product remains clear, you do not have a legitimate product.
Counterfeit Sustanon, bearing the name Loniton. This is a non-existant brand name. This particular amp looks odd immediately as it is much too large for 1ml and could prob hold as much as 4 or 5ml.

Testosterone Cypionate: Eight years ago this oil based injectable was found in abundance on the black market. Today, the tight controls placed on anabolics have made this item almost impossible to find. Aside from the U.S., Spain is the only country producing testosterone cypionate. Since the real U.S. item is highly unlikely to be found, only the 2ml ampules from Leo in Spain can be trusted. Counterfeits of the various American versions are everywhere, so be warned. Testosterone Enanthate: Unlike cypionate, testosterone enanthate is widely produced throughout the world. Found in a wide variety of packaging, it is difficult to pinpoint exactly what to purchase. Here are some helpful guidelines when shopping. The only Multi-dose vials which are safe to buy are those from the two Mexican companies, Brovel and Tornel. The Brovel item is counterfeited, but can be trusted if the vial cap has the raised "Laboratories Brovel" stamping in the metal. Legitimate American vials, as discussed earlier, will be a rare find whereas fakes are abundant. Avoid all American testosterone unless you are absolutely sure of the source. The rest of the testosterone enanthate you will likely come across will be 1ml ampules at a strength of 250mg. For these you can use the freezer test to determine authenticity (See: Sustanon).
