Learn proper forum etiquette.
First, this begins by introducing yourself to the community with a thread in the New Member Introduction subforum. Tell us about yourself, your goals, your experiences, your expectations, etc. Use this subforum for your initial interactions with other members of the community.
Next, you should have many questions about AAS/PED use. Educate yourself by reading and posting your questions/experiences/feedback in one of the 24 relevant subforums. This should be done before you even consider participating in the "Steroid Underground" subforum.
Shortly after doing this, most New Members will quickly gain full access to the MESO Forums.
If you still don't have full access to all the features of the MESO, there is a simple solution: just continue reading, learning, asking, sharing, and posting. (NOTE: posting many threads on MESO-Rx Forum just for the sake of posting may be penalized. Be sure and take the time to post well-thought out questions and/or experiences and information to could be of value to others).
The last questions you should ask are the ones about source acquisition.
