Nandrolone Phenylpropionate (NPP) is an injectable anabolic/androgenic steroid. It is highly anabolic and mildly androgenic. NPP is very similar to the very popular steroid Deca which is nandrolone but with a longer ester (decanoate). Nandrolone Phenylpropionate is, therefore, a shorter acting Deca for all practical intents and purposes.
Anecdotally, it seems to produce less water retention than its longer acting cousin so consistent with injectable testosterones, where we find that shorter esters provide much less water retention. NPP has also been proven to have more side effects than Nandrolone Decanoate especially in regards to reducing the presence of ‘Deca Dick’ and offers a cleaner, sharper look to the muscles than its longer acting cousin.
Due to the chemical structure of NPP this product is susceptible to crashing if exposed to temperatures below 6° Celcius (48.8F) for any length of time. Storage MUST be maintained between 6C and 30C as stated on the vial label and customers in cold climates must be advised that this product could reach you in a ‘crashed’ state. If it does then please read our ‘How to Recover Re-crystallized Gear’ in the forums.
