Sus-250 (also known as Sustanon) is one of the most popular testosterone-based anabolic steroids. It is widely used in bodybuilding and medicine. Sus-250 is actually the trade name for a blend of 4 different esterified variants of testosterone in different proportions. The exact combination of testosterone esters in Sus-250 is as follows:
60 mg Testosterone Phenylpropionate 60 mg Testosterone Isocaproate
100mg testosterone decanoate
The reason for combining the different esters is to create a drug that can provide the patient with the benefits of slow and rapid release of testosterone into the bloodstream. Sus-250 allows a diluted injection schedule up to once every 3-4 weeks.
A brief history of the Sus-250
Sus-250 as Sustanon was originally developed by Organon in the early 1970s to offer a testosterone drug that had certain advantages in medical and clinical settings. The end result is a drug whose injection allows for a dilute administration schedule. It is a convenience for patients. Sus-250 is almost entirely a European product and has never been approved for use in the United States. A drug with a composition very similar to Sus-250 is Omnadren, developed in Poland and distributed in Eastern Europe and the Caucasus.
Sus-250 is popular with athletes and bodybuilders and especially beginners. This is due to the belief that the Sus-250 is worth its price compared to other products, as the Sus-250 is designed for medical purposes, not sports.
Properties on Sus-250
Sus-250 significantly improves muscle protein synthesis, nitrogen retention, increases insulin-like growth factor-1 (IGF-1) production. LIGF-1 is a highly anabolic peptide hormone that plays an important role in recovery processes. In addition, Sus-250 increases the total number of red blood cells, which contributes to better oxygen transport.
Intake and Dosage of Sus-250
The idea of Sus-250 in general is to provide an initial jump in blood testosterone levels 24-48 hours after injection. Testosterone levels then remain elevated for 21 days, thanks to the various esters in the blend.
Sus-250 can and can also be used as a base in a cycle, alone or in combination with other steroids depending on the purpose. An example of an effective mass cycle is the combination of Sus-250 for 12 weeks with Dianabol (Methandrostenolone) for the first 4-6 weeks. Deca-Duarbolin is also often combined with Sus-250 due to its long half-life and is suitable for a cycle of 12 weeks or more. On the other hand, Sus-250 also increased weight in combination with Parabolan (Trenbolone Hexahydrobencylcarbonate), Masteron (Drostanolone Propionate) and Winstrol (Stanozolol).
Those using Sustanon for the first time can expect to gain about 10 kilograms in a few months, using just 250mg of Sus-250 per week. More advanced athletes will obviously need higher doses to achieve the desired effect. Using Sus-250 will suppress natural testosterone production, so using HCG Pregnyl or Anastrozol is advisable.
Cures with Sus-250
Steroid cycle with Sus-250 (for mass)
Products: 15ml 250mg/ml Sus-250 (testosterone blend)
In addition :
For cholesterol: Lipid Stabil (3 capsules/day) and fish oil (4 g/day).
Estrogen control: tamoxifen (20-40 mg/day) or anastrozole (0.5-1 mg/day).
Comment : This cycle for muscle mass is similar to other cycles using testosterone, but here the focus is on the use of Sus-250, a more common form of testosterone blend in Europe. The total steroid dose for the entire cycle is 3750mg, extremely close to the amount used in cycle #2. Cardiovascular effects should be the same as in the previous cycle. Visible androgenic and estrogenic side effects are expected.
Sus-250 Side Effects
The potential side effects of Sus-250 are all related to testosterone side effects, as it is an anabolic steroid directly based on testosterone.
The first concern is estrogenic side effects. Testosterone has an affinity for the aromatase enzyme, which is responsible for converting testosterone into estrogen. Side effects of estrogen include: increased water and fat retention, high blood pressure and gynecomastia. The manifestation of these side effects depends on the individual sensitivity of the individual and the dose administered. Higher doses of Sustanon will increase the incidence of estrogenic side effects. The use of aromatase inhibitors or SERMs (selective estrogen receptor modulators) such as Nolvadex (tamoxifen citrate) is recommended.
Androgenic side effects with Sustanon can also be an issue.Testosterone is readily converted to dihydrotestosterone (DHT) in androgen-responsive tissues in the body. Because DHT is a much more potent androgen than testosterone, this can actually be a problem. Androgenic side effects include: increased sebum secretion from the skin, acne, baldness and increased hair growth on other parts of the body. These side effects can be reduced by supplementing with 5-alpha reductase inhibitors and topical DHT antagonists such as Nizoral.
Virilization is a serious problem for women using testosterone-based anabolic androgenic steroids. For this reason, women are recommended to avoid the use of such steroids. Virilizing side effects include: excessive hair growth, thickening of voice tone, menstrual disturbances and clitoral enlargement.
Testosterone has a negative effect on the cardiovascular system. This mainly results in a change in the cholesterol profile. Sustanon promotes an increase in LDL ("bad" cholesterol) and a decrease in HDL ("good" cholesterol). Additional studies show even worse values with the use of aromatase inhibitors.
It is imperative to lead a healthy lifestyle, that is, a diet rich in omega fatty acids, low in saturated fats and simple sugars. Aerobic exercise should also be included, even while gaining weight.
Suppression of testosterone
Like most anabolic steroids, especially testosterone-based ones, Sustanon suppresses natural testosterone production.
After the cycle ends and your body gets rid of all external hormones, natural testosterone production starts again.The levels will still be low and it will take some time to fully recover. Therefore, post cycle therapy is recommended for most men. The therapy will stimulate natural testosterone production and provide enough testosterone for normal bodily functions, while levels increase naturally. This alone will not cause a full recovery, which will take time, but it will speed up the process. The therapy will prevent cortisol from becoming the dominant hormone, while testosterone levels are low for a long time. If cortisol becomes predominant, it can wreck your physique.
Important note regarding natural testosterone recovery: it does not suggest an initial state of low levels. It also does not suggest serious damage to the functions of the hypothalamus, pituitary and testicles due to misuse of anabolic steroids. Another important note although post cycle therapy is very helpful, leaving the cycle for a short time does not yield good results. This must be taken into account during intensive cycles.
Sustanon or another testosterone based steroid is not hepatotoxic. Liver damage is unlikely.
