Some things about Deca you maybe didn’t know.

Here are some quick points about nandrolone (with links to evidence) you may have never known. Notice I am only linking evidence in humans. As many who read my work know, I will not let a good story get in the way of the truth. Animal models are to be taken with a grain of salt in most cases; but especially in the case of AAS research.

– Nandrolone increased gastrointestinal and renal tubular absorption of calcium and decreased bone reabsorption. This means that deca reduces osteoporosis or increases the rate of bone healing. Fascinating —

– Nandrolone also had the beneficial effects of stimulating the formation of extra-osseous collagen and soft tissue. What this means is that deca increases the repair rate of tendons, ligaments and skin. It may even decrease wrinkles if this repair rate is strong enough —

Numerous studies have shown that DHT is the active androgen involved in maintenance of nitric oxide-mediated penile erections. Unfortunately for Deca, we don’t end up with DHT as a result of 5a reductase like we do with testosterone use, we end up with DHN. It is reasonably hypothesised that this overproduction of DHN compared to DHT is the reason why some users report erectile dysfunction with the use of deca. However, in my experience, I see ED and libido issues with Deca quite rarely.

So there you have it. Deca may induce some of the benefits HGH is renowned for, but it may also cause limp dick in some—albeit it seems a small portion of users and is probably dose related. Okay, cool! That’s all for today folks.

I hope this helps! Any specific questions related to this post do not hesitate to ask in the comments section below or email us at

    Have run nandrolone in both decanoate and phenylpropionate forms multiple times.

    One of my favourite steroids due the healing benefits mentioned above, less water retention than testosterone and in my opinion, less side effects than testosterone at the same dose with better results.

    I run test low with it and do not suffer and ED. I found “deca dick” became an issue when running test moderately with nandrolone.

    Nandrolone in my opinion is the best steroid to use as a mass builder.
    Does the same, if not more than test in regards to lean tissue growth with less side effects WHEN CYCLED CORRECTLY.

    Currently using 125mg test e with 210mg npp plus 375mg of masteron e.

    That cycle is one of my favourites for steady gains with minimal side effects.

    For reference I’m 5”9, sit at around 90kg at approximately 10% bodyfat.

    Large doses aren’t needed!
