Testosterone propionate is a commonly manufactured, oil¬based injectable testosterone compound. The added propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Testosterone propionate is therefore comparatively much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule. While cypionate and enanthate are injected on a weekly basis, propionate is generally administered (at least) every third day. Figure one illustrates a typical release pattern after injection. As you can see, levels peak and begin declining quickly with this ester of testosterone. To make this drug even more uncomfortable to use, the propionate ester can be very irritating to the site of injection. In fact, many sensitive individuals choose to stay away from this steroid completely, their body reacting with a pronounced soreness and low-grade fever that may last for a few days. Even the mild soreness that is experienced by most users can be quite uncomfortable, especially when taking multiple injections each week. The “standard” esters like enanthate and cypionate, which are clearly easier to use, are therefore much more popular among athletes.

Those who are not bothered by frequent injections will find that propionate is quite an effective steroid. As an injectable testosterone it is, of course, a powerful mass drug, capable of producing rapid gains in both much size and strength. At the same time the buildup of estrogen and DHT (dihydrotestosterone) will be pronounced, so typical testosterone-related side effects are to be expected. Bodybuilders generally consider propionate to be the mildest testosterone ester, and the preferred form of this hormone for dieting/cutting phases of training. Some will go so far as to say that propionate will harden the physique, while giving the user less water and fat retention than one typically expects to see with a testosterone like enanthate, cypionate or Sustanon. Realistically however, this is nonsense. The ester is removed before testosterone is active in the body, and likewise the ester cannot alter the activity of the parent steroid in any way, only slow its release. It all boils down to how much testosterone you are getting into your blood with each particular compound ¬otherwise there is no difference between them.

During a typical cycle one will see action that is consistent with other forms of testosterone. Users sensitive to gynecomastia may therefore need to addition an anti¬estrogen. Those particularly troubled may find that a combination of Nolvadex® and Proviron® works especially well at preventing/halting this occurrence (Arimidex or Femara are even more effective options, but are also more costly). Also unavoidable with a testosterone are androgenic side effects like oily skin, acne, increased aggression and body/facial hair growth. Those who may have a predisposition for male pattern baldness may also find that propionate will aggravate this condition. To help combat this we also have the option of adding Propecia®/Proscar® or Avodart®, which will reduce the buildup of DHT in many androgen target tissues. This will help minimize related side effects (particularly hair loss), although it offers us no guarantees. And as with all testosterone products, propionate will suppress endogenous testosterone production soon into the cycle. The use of a testosterone stimulating regimen of HCG and NolvadexlClomid® is, therefore, almost a requirement at the end of the cycle, in order to avoid enduring the dreaded hormonal crash.

The most common dosage schedule for this compound (men) is to inject 50 to 100mg, every 2nd or 3rd day. As with the more popular esters, the total weekly dosage would be in the range of 200-400mg. As with all testosterone compounds, this drug is most appropriately suited for bulking phases of training. Here it is most often combined with other strong agents such as Dianabol, Anadrol 50®, or Deca-Durabolin®,combinations that prove to be quite formidable. However, Propionate is sometimes also used with non-aromatizing anabolics/androgens during cutting or dieting phases of training, a time when its fast action and androgenic nature are also appreciated. Popular stacks include a moderate dosage of propionate with an oral anabolic like Winstrol® (15-35mg daily), Primobolan® (50-150mg daily), or oxandrolone (15-30mg daily). Provided the body fat percentage is sufficiently low, the look of dense muscularity can be notably improved (barring any excess estrogen buildup from the testosterone). We can further add a non-aromatizing androgen like trenbolone or Halotestin®, which should have an even more extreme effect on subcutaneous body fat and muscle hardness. With the added androgen content any related side effects will become much more pronounced.

Women who absolutely must use an injectable testosterone should only use this preparation. This is simply because blood levels are easier to control with it compared to other long-acting esters. Should virilization symptoms develop, one would not wish to wait the weeks needed for testosterone concentrations to fall after a shot of enanthate. The dosage schedule should also be more spread out, with injections coming every 5 to 7 days at most. Obviously, the dosage would be lower as well, generally in the range of 25mg per injection. Androgenic activity should be less pronounced with this schedule, giving blood levels time to sufficiently decrease before the drug is administered again. In order to further reduce any risks, the duration of this cycle should not exceed 8 weeks. Should a stronger anabolic effect be needed, a small amount of Durabolin® (Deca-Durabolin® if unavailable), Oxandrolone, or Winstrol® could be added. Of course, the risk of noticing virilizing effects from these drugs may increase, even with the addition of a mild anabolic. Since many of the masculinizing side effects of steroid use can be irreversible, it is very important for the female athlete to monitor the dosage, duration and incidence of side effects very closely.

Testosterone propionate is very abundant on the black market right now, perhaps more so than it was a couple of years ago. This probably has a lot to do with the fact that it is a very cheap steroid to manufacture next to some of the longer acting esters. In going over some of the more popular items circulating the black market at this time, I can offer the following observations.

Animal Power has a propionate product in Mexico called Propiotest 100. This is a 100mg/mL steroid, which comes in a 10mL multi-dose vial. The company uses several security checks on its injectable products, including a security holographic sticker with the company logo embedded in the image (see: Security Stickers). Be sure to look for these when shopping.

Quality Vet is making Propionat QV 100 in Mexico, which is another 100mg/mL preparation in a 10mL multi-dose vial. Just be sure to look for their holographic security sticker when shopping, which should assure a safe purchase.

Testosterona from Brovel in Mexico is still abundant. Brovel has been around for a long time, and has always delivered a quality product for an excellent price. Remember to look for the Brovel Hologram sticker to be sure you are getting the real thing, as there are a lot of fakes of this line floating around (not this product in particular though).

Ttokkyo has ceased operations in Mexico. This firm used
to make an excellent propionate product, but even old stock will be off the black market at this point. Avoid.

Testopro L/A from Loeffler in Mexico contains a whopping 250mg/mL, at least according to the label on this 10mL multi-dose vial. Loeffler products seem to have been hit or miss in quality lately though, and a previous test of this item in particular showed it to have a bit over 133mg of testosterone propionate in each mL. This is a little better than half of the label claim, which leaves us wondering if Loeffler has ever produced a true 250mg/mL testosterone propionate. Hopefully, I will have the opportunity to test some lots in the future to find out.

Testolic from Body Research is no longer being made, following a raid on their facilities last year. Currently the Body Research name is being used by counterfeiters in Eastern Europe, mostly to make products with questionable contents.

British Dragon also makes Testabol Propionate in Thailand, another export only item (you will not find it is pharmacies when shopping on vacation). The BD line is very hot right now, with a very good reputation. Note that the have stopped using hologram stickers on their injectable products. Instead, they are using a red or blue metallic foil inlay on their labels. Be sure the product name is also formed directly into the plastic on the flip off top, and once removed reveals a dragon logo directly in the rubber stopper.

BM Pharmaceuticals is a quasi-legit company in India that makes a brand of testosterone propionate called Testopin-100. As the name indicates, it contains 100mg/mL of steroid. It is packaged in both 1 mL glass ampules and 2mL multi-dose vials. Currently, fakes of this line are not much of a problem.

Jelfa makes Testosteronum Propionicum in Poland, which makes its way most often to the European black market (rarely to the U.S.). However, it only contains 25mg of steroid in each 1 mL ampule, so it doesn’t stack up much to the more popular 100mg/mL products here in the States.

Virormone is still manufactured in the U.K., most recently by the firm Nordic. These 2mL 100mg ampules are not extremely popular in the U.s., but do circulate here from time to time. The UK has been taking steroid distribution more seriously as of late, limiting greatly the supply of domestic drugs making it to the international black market.

No testosterone propionate products are being manufactured in the U.S. at this time, so avoid all such products on the black market.

Vetoquinol sells a propionate in Canada, called Anatest. This steroid used to be sold under the Sterivet label, which is not another company but the parent company of Vetoquinol. Anatest contains 100mg/mL of testosterone propionate in a 10ml vial, giving it a dosage and volume comparable to many of the higher dosed veterinary items on the black market. Combine this with the rigid standards of Canadian drug manufacturing (if you find a legitimate product), and Anatest starts looking like an excellent product if you come across it. Unfortunately, the firm doesn’t use any hologram or sophisticated security measures. Shop carefully.
