1) The trick to effectively using a PNP type product is too learn how deeply to inject. Too shallow and you may get a lumpy or blurred appearance, too deep, and the oil may travel to a space you don't want to increase the size of (like your armpit!).

2) Start slow! It hurts, there is no question, it will hurt for the first 3-4 weeks, 1-2 being really bad. For this reason you very slightly increase your dosages to get the desired results. Here was what I typically recommend:
Weeks 1-2:
1cc per muscle group every 4 days
Weeks 3-4:
2 ccs per muscle group every 3 days
Weeks 5-6:
3cc's per muscle group every 3 days
Weeks 7-8 off
Repeat, or increase dosages more...

3) Get a tan! An excellent product if you are unable to tan is Tan Perfect, use it. Or get a natural tan. PNP type products can cuase brusing and small dark spots if injecting improperly. They don't look bad, but to help cover them, dark skin does wonders, as well as makes you look much more defined.

4) ALWAYS ASPERATE! You should always asperate when injecting, but this is of great importance when injecting into muscle group literally PACKED with nerves, and blood vessels. Every time you stick a needle in yourself, you run a very small chance of hurting yourself, but if you asperate, you can almost totally eliminate this from happening, which is the idea....GET BIG, not dead. Mind you, it's not just a PNP type product that will do this, any injectable product, out side of blood materials, holds the potential to cause damage.
