Bolus is a practical and reference guide for the use of recombinant human growth hormone (rhGH; GH) and GH secretagogues (GH releasing peptides). Bolus represents a breakthrough in planning and designing protocols for contest bodybuilding and anti aging applications. This research-based text details how to systematically examine the physiological parameters required for crafting an optimal, objective oriented course (protocol) for the purpose of competitive untested bodybuilding. The author brings years of practical and research work, as a bodybuilding practitioner and coach for contest and lifestyle bodybuilders, in order to share his unique insights concerning planning, designing, and implementing protocols that use this class of growth factors - GH in its recombinant and secretory forms. This text is written in a manner that challenges professionals, and includes in its intended audience doctors and chemists, while remaining accessible to bodybuilding practitioners and coaches. It begins by giving the reader the basic tools for understanding GH research. This scientific foundation empowers the reader to formulate a sound plan and design process. Next, the text examines how to apply this knowledge using clear worked examples. Finally, a theoretical section that contains basic scientific facts about GH in its recombinant and secretory forms is provided as a reference. Each section (1. Introduction to Research, 2. Practical Applications, and 3. Theoretical Reference) is written in a standalone manner so that the reader can refer back to the material as needed.
