It is never gonna be a impressive as clen. But the fact that it has the effects it has with essentially zero sides for most people is why alot of people like it, including myself.Can you post links to the studies you’ve read? The 4 studies I’ve read in support of albuterol use were pretty disappointing.
So I looked again and there's really not much impressive research around salbutamol for fat loss. In my experience, anecdotally, it has significantly helped my cuts before, but it certainly is no clen. I've never done clen either so yeah. There are a few studies that show salbutamol to have fairly impressive activity on hypertrophy and muscle mass. So perhaps in a cut it is simply surpassing appetite and possibly helping to maintain muscle to some degree, especiallywhen paired with anabolics. I don't have a solid answer. anyway, links below.
Hypertrophy/power output/strength:
Effect of salbutamol on innervated and denervated rat soleus muscle - PubMed
The objective of the present investigation was to perform a 14-day time-course study of treatment with salbutamol, a beta2 adrenoceptor agonist, on rat soleus muscle in order to assess fiber type selectivity in the hypertrophic response and fiber type composition. Male Wistar rats were divided...

Beta2 -adrenoceptor agonist salbutamol increases protein turnover rates and alters signalling in skeletal muscle after resistance exercise in young men - PubMed
The effect of beta<sub>2</sub> -adrenoceptor stimulation on skeletal muscle protein turnover and intracellular signalling is insufficiently explored in humans, particularly in association with exercise. In a randomized, placebo-controlled, cross-over study investigating 12 trained men, the...

β2-Adrenergic agonist salbutamol augments hypertrophy in MHCIIa fibers and sprint mean power output but not muscle force during 11 weeks of resistance training in young men - PubMed
In this study, we examined the effect of β<sub>2</sub>-agonist salbutamol at oral doses during a period of resistance training on sprint performance, quadriceps contractile function, skeletal muscle hypertrophy, fiber type composition, maximal activity of enzymes of importance for anaerobic...

Metabolism and fat loss:
The effect of caffeine and albuterol on body composition and metabolic rate - PubMed
In rats, albuterol with caffeine produced significantly greater increases in lean body mass and reductions in fat mass without changes in food intake after 4-8 weeks of treatment. Since caffeine and albuterol are approved for the treatment of asthma in children and adolescents at the doses...
