Profile
Sustanon250 is the most well-known testosterone mix ever produced. Organon’s Sustanon250 combines the benefits of short and long-acting ester testosterones in a single injection. This would enable the person to maintain constant testosterone blood levels while getting quick acting effects.
There are a few additional advantages to taking Sustanon 250 throughout a cycle owing to the ester mix. In comparison to other testosterone derivatives, Sustanon has less side effects. Increased muscular growth, strength, libido, and recuperation after each training session.
Sustanon does not have the same sudden peak and rapid fall as other esters since it is made up of four distinct ester chains that release at various periods. Regular testosterone levels assist to avoid estrogen surges and severe HPTA (hypothalamic-pituitary-gonadal axis) suppression.
Although long-term usage of any testosterone may produce side effects, sustanon is blamed by many bodybuilders for milder consequences. As with any other testosterone ester, this is a myth.
Esters
Because each ester has a half-life, the steroid released from the ester peaks and falls at various periods. Imagine a rapid rise followed by a rapid fall in the steroid’s blood serum levels. This may be a few hours or days.
Testosterone, like other steroids, has a limited half-life. In order to bind an ester chain to testosterone, producers utilize a chemical procedure. The ester chain makes the hormone oil soluble and slows its excretion. As a consequence, testosterone cannot bind to androgen receptors until the ester chain is removed.
Finally, introducing the ester chain reduces the steroid’s dosage frequency to just a few times each week. This compares to many daily doses of the basic hormone. The basic hormone, without an ester link, enters and exits the body quickly. This requires several daily shots to maintain a successful cycle of TRT therapy.
Sustanon 250 uses four esters in the same oil carrier to provide consistent testosterone release from each injection. The idea behind combining four esters is to create a cascade effect, utilizing the peaks and troughs of each ester to maintain levels stable. They developed a near-perfect TRT steroid by mixing various esters. Meanwhile, the shorter-to-mid-length esters like phenylpropionate build up, while the longer decanoate ester is only nearing its maximal release.
Testosterone Decanoate 100mg
This is a long ester used in steroid. It has a half-life of about 2 weeks (roughly 15 days), implying an active life of nearly a month. In simple terms, decanoate takes 30 days to leave your system after injection. This ester’s peak should be around 11-12 days, not 15.
Sustanon is a “once a month” medication due to the decanoate ester. Based on this ester alone, users believe you can inject one sustanon each month. This is true for TRT, but not true for bodybuilding. Consider that by day 11-15 (two weeks in), you’ve peaked and used up most of the steroid. So you need another injection to maintain blood levels.
Testosterone Isocaproate 60mg
This ester is utilized to bridge the gap between propionate and decanoate esters. Because it has a 9 day half-life, I’ve never understood why it wasn’t utilized instead of cypionate or enanthate. I think it’s price.
Being developed for TRT, we may presume sustanon’s margins are large. Organon is renowned for earning 500%+ margins on this steroid. Using more costly esters is therefore unnecessary. Why mess with what works? They will lose money if they add the more effective cypionate or enanthate esters.
Testosterone Phenylpropionate 60mg
This is another mid-range ester utilized to maintain testosterone levels as the propionate ester leaves the system and the decanoate ester takes over. Though some research indicate a 5.5 day half-life for testosterone phenylpropionate, it is generally considered to be 4.5 days. Like propionate. It’s strange that this ester is utilized since its half-life is so close to propionate.
Based on my research, I think the phenylpropionate chain is chosen because base propionate has a shorter half-life than experts assume. Exogenous testosterone is processed differently by males. So the phenyl form of propionate is given to maintain testosterone levels.
Testosterone Propionate 30mg
One of the most common testosterone esters ever utilized, propionate is one of the shortest esters used in steroid preparations. Using testosterone propionate alone, inject every other day (EOD). The isocaproate and phenylpropionate ester are just beginning to fully release when the propionate ester wears out.
Propionate has a half-life of 4.5 days, although many bodybuilders think it is closer to 3. This may be due to the way the ester is cleaved by various guys with varying health.
The propionate ester is the sustanon formula’s foundation. It’s included as a TRT medication since it instantly boosts males with TRT symptoms. Imagine how wonderful you feel after years of poor libido, depression, and weight gain due to low testosterone levels following your first sustanon injection. Adding propionate to sustanon TRT is mostly a psychological benefit.
Injecting
Some people wind up injecting sustanon every 3 days. They believe it helps them use the propionate ester and maintain a constant medication release. Although the four ester was created to save the user several injections each week, it seems bodybuilders prefer to use it every three days. But this isn’t the optimum sustanon dosage. The best injection schedule is 5 days. Most users will happily inject once a week.
Adverse effects Sustanon 250 has the same side effects as any testosterone. The aromatase enzyme converts testosterone to estrogen, causing water retention and gynecomastia (bitch tits). The 5-reductase enzyme converts testosterone to dihydrotestosterone (DHT), causing hair loss and prostate enlargement. These adverse effects may be reduced by using SERMs like nolvadex (tamoxifen) or aromatase inhibitors like aromasin.
Higher testosterone levels cause more oil to be produced on the skin, increasing the risk of acne. If you consume 500-750mg sust per week or more, you will sweat more and have a “solvent-like” urine smell.
Using testosterone raises bad cholesterol levels. You should eat more omega-3 fats, probiotics, and fiber (psyllium husk).
