I also found l-phenylalanine to give a good energy boost (I found Twinlab l-phenylalanine to be an effective brand). L-phenylalanine easily crosses the blood brain barrier & eventually converts to norepinephrine & dopamine giving an energy boosting & anti-depressant effect. The usual dose is 500 to 1500mg with water on an empty stomach (if you have any protein at all in your stomach the phenylalanine will not be absorbed). I found it is good to set your alarm for a few hours before you have to get up for work, take the l-phenylalanine with a full glass of ice water & immediately go back to sleep & then you will be energized at work all day. You have to give l-phenylalanine a chance, probably a week before you will notice any energy increase, with higher doses giving more of an increase. I would NOT use DLPA- which is d,l phenylalanine unless you have chronic pain, because d,l phenylalanine has much more difficulty passing through the blood brain barrier. L-Tyrosine (the precursor to dopamine) does not cross the blood brain barrier & has been shown in trials to have no effect on most people.
The most energizing agent available over the counter is Primatene tablets. Primatene also is good to take in the morning if you have trouble waking up for work. Primatene tablets contain d,l ephedrine hcl USP which is the strongest form of ephedrine available & I have found it to have effects similar to Dexedrine or Adderall but unfortunately with absolutely no euphoria & some dysphoria (rapid heartbeat). It works well with 200 mg of caffeine, & could be used in this combination as a weight loss drug/thermogenic that is safer & more effective than Xenadrine. The maximum dose at one time is 50 mg (4 tablets) but that might make you too wired & dysphoric. I would recommend that you take 25 mg (2 tablets). The effects last a fairly long time 4-6 hours. But be foreworned- weight loss, lack of appetite, rise in blood pressure and pulse, insomnia, & rapid heartbeat are the usual side effects (although caffeine has similar side effects). Do not exceed 100 mg in 24 hours.Most importantly!
Do not use if you have high blood pressure or heart problems &
Do not use the herbal form of ephedra- the herb ephedra is much more dangerous than the ephedrine in Primatene tablets which is USP certified pharmaceutical grade. You never know exactly what is in the ephedra herbal formulations, & so they not only do not work as well, they are more dangerous. It appears nearly all the complaints of ephedrine complications come from the herbal form ephedra found in Xenadrine, metabolife, ripped fuel & various others- I have never heard of complaints from Primatene or Bronkaid (weaker l-ephedrine sulfate) asthma tablets.
