The original preload, as prescribed by Dr. Tom:
100-250mg 5-htp
500-1500 L-Tyrosine
500-1500 DL-Phenylalanine
1000-2000 L-Glutamine
You may also want to take some magnesium to lesson jaw clenching.
Start low with the 5htp, it can make you sick to your stomach. Some people shy away from the Tyrosine since it ups dopamine production, and dopamine is one of the contributors to axon trimming, so it *may* result in higher tolorance.
Take the load 1 to 2 hours before dropping your first pill with OJ or grapefruit juice. When you take additional X, take 50-100mg 5-htp + 500-1000mg DLPA. Take 50-100mg 5-htp before you go to sleep for the night, and 50mg again when you wake up.
5-htp (L-5-hydroxytryptophan) is used by the body to make seratonin (L-5-Hydroxytryptomine), that wonderful brain chem that makes you feel so damn good on X. Tolorance and post-roll depression are caused by extremely low levels of seratonin, so even if you skip the other aminos, take the 5-htp. DLPA gives you an energy boost, and is used in the production of endorphins, never a bad thing to have... just make sure you get *DL*, not just D or L. Glutamine is one of the two fuels (along with Glucose) used by the brain. If you are not going to be eating for upwards of 18-24 hours, making sure your brain is fed is always a good idea
I'm a convert, rolling without pre-loading is like having less X IMO. And it takes the day after depression and turns it into an afterglow. Your mileage may vary.
