Subjects performed 9 wk of isokinetic knee extensions twice weekly. Albuterol (N = 13) or placebo (N = 9) was administered for 6 wk; groups received 16 mg.d-1 of either treatment. Training consisted of three sets of 10 repetitions at 45 degrees.s-1. Data were collected at weeks 0, 6, and 9. Concentric and eccentric variables examined included: peak torque (CPT, EPT), total work (CTW, ETW), average power (CAP, EAP), time to peak torque (CTTPT, ETTPT), peak torque to body weight ratio (CPT/BW), and work to body weight ratio (CW/BW, EW/BW). Other variables included: thigh circumference (CIRC), thigh cross-sectional area (CSA), forced vital capacity (FVC), and forced expiratory volume (FEV1), MANOVA and the Dunn-Bonferroni post-hoc found differences within groups for CPT, CTW, CAP, CPR/BW, EPT, ETTPT, and CSA. Interactions were noted for CW/BW, ETW, EAP, EPT/BW, and ETW/BW; with persons administered albuterol yielding superior values. CW/BW, ETW, and EAP showed interactions at post-testing, while EPT/BW and EW/BW interacted at both midtesting and post-testing. Results indicate therapeutic doses of albuterol administered with resistance exercise may augment strength gains.
Here's a study indicating it's dosen't screw up your workout like Clen can sometimes:-

Effect of salbutamol [the European name for Albuterol) on muscle strength and endurance performance in nonasthmatic men.
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.

Effects of oral albuterol on serum lipids and carbohydrate metabolism in healthy men.

beta(2)-Selective adrenergic agonists are used in the management of bronchial asthma and preterm labor. Due to their ability to increase muscle strength and size in animal models, new applications for these agents are also being explored for neuromuscular disorders and in rehabilitation. However, the effects of long-term beta(2)-agonist administration on lipoprotein and carbohydrate metabolism are incompletely understood. This investigation evaluated the effects of a beta(2)-agonist, albuterol, on serum lipids and carbohydrate homeostasis in eight healthy nonsmoking men aged 24 to 61 years. Collection of fasting blood samples was completed in duplicate on separate days at baseline, during 14 days of oral albuterol administration (Proventil Repetabs, 8 mg twice daily; Schering Pharmaceuticals, Kenilworth, NJ) and during a 7-day washout period. Carbohydrate homeostasis was evaluated using the minimal model technique at the end of the baseline and albuterol periods. Fasting glucose and insulin, intravenous glucose tolerance, acute insulin response to intravenous glucose (AIRg), insulin sensitivity (Si), and glucose effectiveness (Sg) were not significantly changed during albuterol administration. Significant alterations (P < or = .02) were observed in total cholesterol ([TC] -9.1% +/- 2.5%), low-density lipoprotein cholesterol ([LDL-C] -15.0% +/- 2.9%), and high-density lipoprotein cholesterol ([HDL-C] +10.4% +/- 3.2%) concentrations, as well as the TC/HDL-C (-17.4% +/- 2.6%) and LDL-C/HDL-C (-22.9% +/- 2.4%) ratios. During washout, TC and LDL-C returned to baseline levels, whereas HDL-C remained elevated by 5.8% +/- 2.4% (P < .05). Thus, albuteroladministration was associated with favorable changes in the serum lipid profile without marked impairment of glucose tolerance or its physiologic determinants.
So by taking my recommended sprays, not only does it help my breathing, but it helps with my training too? or is the albuterol discussed in the studies able to be injected or taken through an oral pill?
Clen completely cashes my muscle glycogen. I can't lift heavy, and even when I lighten the weight I fail way too early in my set and without warning. I don't see how Albuterol would not do this. It may be somewhat better if you take it first thing in the morning and workout at night, but I think the depleted glycogen that clen causes leads to increased lipolysis, personally. So, if you spent the time between your morning dose letting your muscle glycogen refill, I'm not so sure you would see the same fat burning benefits. These are just random thoughts, though.
