NPP 200

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.

Some of our injectables are highly concentrated and will produce pain during injection and afterward (PIP) if injected directly. To prevent this, you need to dilute (cut) these HIGH-MG injectables with a carrier oil/base.

Generally, anything above 250mg/ml should be diluted before injection.

How to Dilute:

1. Determine which base you need:
   Look at the ingredients list on the product page OR on the label.

   Made with Grape seed oil (GSO)? Dilute with Sterile Oil.

   Made with PEG/MEG/Glycol base? Dilute with PEG/MEG BASE.

2. Mix your product with the corresponding base in a syringe (or a new sterile vial).
   Initially, mix with a 1:1 ratio, diluting more if needed.
   Example: Mix 0.5ml of Gigatest 750 with 0.5ml grape seed oil in the same syringe.
