Asthma inhalers are not comparable to liquid albuterol
I am hearing that there has been some debate on the boards about whether or not liquid Albuterol is effective because many have asthma inhalers and it hasn't done anything for them!
First off, asthma inhalers don't have anywhere NEAR the concentration of liquid Albuterol. LA is formulated at 4 MG/ML, you would get a tiny fraction of that in an inhaler.
The reasons that you would get LA as opposed to clen are:
1) shorter half life, allowing for greater control over its stimulatory effects.
2) can be run longer than clen with less receptor downregulation, allowing for an overall greater fat loss.
3)Less chance of negative side effects. Because of clens long half life, more and more of it needs to be taken in order for it to remain effective allowing for a greater build up in your system and therefore a higher chance of negative side effects.
4) More studies showing improved strength and endurance in humans with Albuterol.

PURPOSE: The ergogenic effect of acute beta2-adrenergic agonist administration in nonasthmatic individuals has not been clearly demonstrated. Therefore, the acute effects of oral administration of the beta2-adrenergic agonist salbutamol (4 mg) on muscle strength and endurance performance were studied in 16 nonasthmatic men in a double-blind randomized cross-over study. METHODS: Peak expiratory flow (Mini Wright Peakflowmeter), isokinetic strength of the knee extensors and knee flexors at four angular velocities (Cybex II dynamometer), and endurance performance in a cycle ergometer test until exhaustion at 70% of maximal workload were measured. RESULTs: Peak expiratory flow increased from 601 +/- 67 L x min(-1) to 629 +/- 64 L x min(-1) after salbutamol (P < 0.05). Peak torque was higher after salbutamol than after placebo (4.4% for the knee extensors, 4.9% for the knee flexors) (P < 0.05). Mean endurance time increased from 3,039 +/- 1,031 s after placebo to 3,439 +/- 1,287 s after salbutamol (P = 0.19). When four subjects complaining about adverse side effects were excluded from the analysis, the increase in endurance time (729 +/- 1,007 s or 29%) was statistically significant (P <-0.05). Salbutamol did not affect VO2, respiratory exchange ratio, heart rate, and plasma free fatty acid and glycerol concentration during exercise; plasma lactate and potassium concentrations were increased (P < 0.05). CONCLUSIONS: Under the conditions of this study, oral salbutamol appears to be an effective ergogenic aid in nonasthmatic individuals not experiencing adverse side effects.

INTRODUCTION: While resistance exercise (REX) attenuates knee extensor (KE) mass and strength deficits during short-term unloading, additional treatments concurrently administered with REX are required to reduce the greater losses seen with longer periods of unloading. METHODS: To determine whether Albuterol helps REX attenuate unloading-induced KE losses, two groups of subjects strength trained their left thigh three times per week, and otherwise refrained from ambulatory and weight-bearing activity for 40 d while receiving a capsule dosing treatment (Albuterol, placebo) with no crossover. A third group served as unloaded controls (CTRL). On days 0, 20, and 40, the following data were collected from the nonweight-bearing (left) thigh: cross-sectional area (CSA); integrated electromyography (IEMG); and concentric and eccentric KE strength measures. Thigh CSA was estimated using anthropometric methodology. IEMG was used to provide root mean square (RMS) values from submaximal (100 nm) and maximal isometric contractions. Concentric and eccentric strength were measured from eight-repetition unilateral leg press sets. RESULTS: Repeated-measures mixed-factorial 3 x 3 ANCOVAs with day 0 values as a covariate showed group by time interactions for concentric and eccentric total work (CTW, ETW). Tukey's post hoc test showed REX-Albuterol evoked significant (p < 0.05) day 40 CTW and ETW gains vs. within-group day 0 and within-time REX-placebo and CTRL values. By days 20 and 40, CTRL subjects incurred significant decrements. CONCLUSIONS: Albuterol augmented the effects of REX to increase CTW and ETW. Research identifying possible mechanisms responsible for such changes, as well as the safety of REX-Albuterol administration in other models, is warranted
