This substance is very similar to the more common and well-known Deca Durabolin with main ingredient nandralone decanoate. The main difference between the two is the ester attached to the nandralone compound. Deca 100 Fast has a shorter phenylpriopionate attached than the more popular long acting decanoate.
Deca Durabolin releases from the site of injection over a 2 to 3 weeks period. Deca 100 Fast releases from the injection site and lasts about a week in the system. Deca 100 Fast is therefore best when being injected every 2 to 3 days to keep the levels in the system level. Apart from the time these two substances releases and last in the system Deca Durabolin and Deca 100 Fast are virtually interchangeable.
Nandralone phenylpropionate shows a sharp increase in blood serum levels of the free form of nandralone within 24 to 48 hours from the time of injection. Because of this sharp increase and quick release of nandralone this product is sometimes preferred to the longer acting version. After athletes compete and they battle with joint pain they prefer this substance because the longer acting version will take to long to kick in.
This substance is not as androgenic as testosterones but this does not mean it is not androgenic at all. At high doses it will have some androgenic effects. In other words at low doses you will have very few androgenic effects but at high doses you might experience oily skin, acne, and body/facial hair growth. Male pattern hair loss, deepening of voice and clitoral enlargement in females is also possible. Liver toxicity with this substance is very unlikely because it is not a c-17 alpha alkylated.
All anabolic steroids have a tendency to reduce HDL (good) cholesterol and increase LDL (bad) cholesterol. The relative impact of an anabolic/androgenic steroid on serum lipids is dependent on the dose, route of administration (oral vs. injectable) type of steroid (aromatizable or non-aromatizable) and level of resistance to hepatic metabolism. With regards to nandralone at a dose of 600mg per week over 10 weeks demonstrated 26% reduction in HDL cholesterol levels. This suppression is slightly greater than an equal dose of testosterone over an equal period. In other words it shows a slightly more negative impact on HDL/LDL ratio with nandralone than with testosterone cypionate. It’s always recommended to accompany the use of this product with a low saturated fat diet and a cardiovascular exercise program.
Nandralone phenylpropionate in doses sufficient to promote muscle growth does suppress endogenous testosterone production. One 100mg nandralone phenylpropionate injection shows a rapid suppression of serum testosterone levels. After about 2 to 3 days after the injection the serum testosterone levels will decrease by approximately 30% of the initial level. Testosterone levels will increase to a normal level after about 2 to 6 months.
Doses for men vary between 200mg and 400mg over an 8 to 12 week period. The weekly dose is usually split into two doses per week due to the short acting nature of the phenylpropionate ester. Recommended dose for woman are 50mg per week (single dose once a week injection) for no longer than 4 to 6 weeks.
200mg to 400mg per week divided in two injections in the week seeing that its short acting for men.
