For bodybuilding beginners dosages of 200mg per week are usual. This is distributed in the first two weeks to 2 injections of 100mg every days. An injection of 200mg per week is then usual.
For advanced bodybuilders dosages of 200 – 600mg per week are usual.
Dosages of 1000 – 1600 mg per week can be found in the professional area. In the dosage range of more than 600mg / week you should consider increasing the dosage of other steroids since the side effects increase with Nandrolone Decanoat at doses over 600mg per week disproportionately.
Unfortunately, Deca Durabolin usage very commonly has the adverse side effect of interfering with recovery of natural testosterone production after a steroid cycle . Adverse side effect on libido and/or erectile function is also common, but typically only when dosage is at least 200-400 mg/week or when the drug is used alone at any effective dose. Problems are worse when Deca is not combined with testosterone or substantial doses of more androgenic compounds such as trenbolone , Masteron , or Dianabol . There is wide individual variability in response with regard to side effects on libido and erectile function. Depression of mood is also possible.
The initial color in vial A is red brown, vial B orange brown for GSO oil and lighter for MCT oil. You can see difference for example between trenbolone where it is bright green. There are two different test agents in each vial, which will react in different way to different chemicals. Any discoloration in vial A or B will also indicate presence of contamination. This is why you need both test vials to confirm presence of steroids and their quality. Some steroids will give different initial color in vial A. This is how you can distinguish them. Nandrolone decanoate (oil based) under UV is mat green for GSO and Arachis oil but lighter green for MCT oil. See the color coding for NPP there is huge difference and there is no doubt if you have deca or NPP.
