Albuterol, clenbuterol, salbutamol, salmeterol hepsi de beta 2 adrenerjik agonist grubundan. Hayvan çalışmalarnda yağsız kas kütlesini artırdığı ve yağ kütlesini(lipolizi artırarak) azalttığı bulunmuş bir madde. İnsanlar üzerinde yapılan böyle bir çalışma görmedim. Etik olmayacağı için yapılması da uygun değil. İnsan çalışmaları genel olarak yan etkilerinden bahsediyor. Genellikle forumlardan ve internetten okuyup bilg edinmişsin sanırım. Sporcu beslenmesindeki ergojeniklerle ilgili bir kitaptan bilimsel bir yayın ekleyim.
"Potential Negative Effects on
Muscle, Bone, and Cardiovascular
Function
Female rats treated with clenbuterol injected subcutaneously or sham injected with the same volume of fluid carrier each day for 14 days increased (1) muscle mass, (2) absolute maximal force-generating capacity, and (3) hypertrophy of fast- and slow-twitch muscle fibers.47 A negative finding showed hastened fatigue during short-term, intense muscle actions. In other studies, regular exercise and regular exercise combined with clenbuterol decreased the progression of muscular dystrophy in mdx mice as reflected by increases in muscle force-generating capacity.208 The group receiving clenbuterol also experienced increased muscle fatigability and cellular deformities not noted in the exercise-only group. Other research with mice indicates a decrease in force production in isolated intact skeletal muscle fiber bundles with clenbuterol administration.124
This negative effect on muscle structure and function may explain findings that clenbuterol treatment negated the benedcial effects of exercise training on endurance performance of animals, despite increases in muscle protein content.84,178 Clenbuterol treatment induced muscular hypertrophy in young male rats, but it concomitantly inhibited the longitudinal growth of bones.105 This effect may relate to clenbuterol’s acceleration of epiphyseal closure in the bones of growing animals and certainly would contraindicate its use for prepubescent and adolescent humans.
Reported short-term side effects in humans accidentally “overdosing” from eating clenbuterol-tainted meat include the following eight negative effects:
1. Skeletal muscle tremor
2. Agitation
3. Palpitations
4. Dizziness
5. Nausea
6. Muscle cramps
7. Rapid heart rate (tachycardia)
8. Headache
