Equilon 100
Active Substance: Equilon 100
Description
What is Equilon 100?
Equilon 100 is a non-pharmaceutical, multi-ester blend of the anabolic steroid boldenone. It is designed to provide a sustained release of the active hormone into the body over time. The "100" in its name typically refers to a concentration of 100 mg of boldenone per milliliter.
Its reported composition is a mix of different esterified forms of boldenone, which have varying half-lives:
-
Boldenone Acetate: ~10 mg
-
Boldenone Propionate: ~30 mg
-
Boldenone Cyclopentylpropionate: ~20 mg
-
Boldenone Undecylenate: ~40 mg
This combination is intended to create more stable blood levels of the drug, with the shorter esters (acetate and propionate) providing an initial effect and the longer esters (cyclopentylpropionate and undecylenate) maintaining the effect over an extended period. It is sometimes compared to "Equipoise" (boldenone undecylenate) or "Sustanon" (a multi-ester testosterone blend).
Reported Benefits and Side Effects
Benefits:
-
Increased lean muscle mass with less water retention compared to some other steroids.
-
Improved appetite, enhanced recovery from training, and strength gains.
-
Lower estrogenic side effects than steroids that aromatize more readily.
-
A potentially favorable anabolic-to-androgenic ratio.
Side Effects:
-
Androgenic effects: These include acne, increased body and facial hair, and accelerated male pattern baldness in those genetically predisposed.
-
Estrogenic effects: Although boldenone has a lower aromatization rate, it can still cause estrogen-related issues such as gynecomastia (development of male breast tissue), water retention, and fat gain.
-
Cardiovascular risks: Boldenone can negatively impact cholesterol levels (decreasing HDL or "good" cholesterol and increasing LDL or "bad" cholesterol) and may raise blood pressure, increasing the risk of cardiovascular disease.
-
Endogenous Testosterone Suppression: The use of exogenous steroids can suppress the body's natural testosterone production, which can lead to testicular atrophy and fertility issues.
-
Virilization in Women: Use by women carries a high risk of virilization, which includes voice deepening, clitoral enlargement, and menstrual irregularities.
-
Other Risks: Potential for injection site pain and infection, and possible negative effects on the liver and kidneys.
Pros and Cons
Dosage and Frequency
According to non-medical sources, a typical dosage for men is approximately 200–600 mg per week. For women, the reported dose is much lower, around 50–100 mg per week, but with a high risk of virilization.
Due to the mixed esters, one or two injections per week are often reported to be sufficient to maintain stable blood levels. Cycle lengths are typically cited as 8–12 weeks.
Half-Life and Detection Time
The half-life of one of its main components, boldenone undecylenate, is about 14 days. However, the presence of multiple esters with different half-lives means the overall "active life" is a blend of these rates.
The detection time, or how long the substance can be found in the body via drug testing, is reported to be very long due to the undecylenate ester. Some sources report it can be detectable for up to 5 months.
Estrogenic, Progestogenic, and Prolactin Effects
-
Estrogenic Effects: Boldenone does aromatize into estrogen, but at a lower rate than testosterone. As a result, estrogenic side effects can occur but are generally considered less severe.
-
Progestogenic Effects: Boldenone is not considered a highly progestogenic steroid; it does not strongly activate progesterone receptors.
-
Prolactin Effects: Boldenone is not known to be a strong stimulator of prolactin. However, some anecdotal reports mention the possibility of a minor increase, which can be compounded by other compounds in a cycle.
Anabolic:Androgenic Ratio
The reported anabolic-to-androgenic ratio for boldenone is
. This means that its anabolic (muscle-building) strength is considered equal to testosterone, while its androgenic (masculinizing) strength is approximately half that of testosterone.Pharmacological Properties
