Title: Secrets of the Fringe Part 4

Timeline: Season 2, (I would now place this whole fic after Bishops Reunion 2:14 coz I Yesterday I googled the show and found that 2:15 Jacksonville looks set to be the start of the storm. Jacksonville airs Feb 4 2010)

Characters: The whole FRINGE cast

Summary: walter makes sense of the drugs

Disclaimer: I own them, in my dreams, no seriously I do, I get to analize them, take them apart, it's great fun.

However in real life someone else has the rights and gets all the money, not that I mind. As long as they don't sue me for playing.

Notes: A great amount of research went into this chapter of the fic. All of the drugs mentioned here are either banned as stated, and were availible when Cortexiphan was developed. All of the drugs mentioned, are the component names which Walter would know drugs to be. Please don't try to recreate any of these drug coctails, chanes are you'll kill yourself

Beta: Thanx again Chickideeee. this one she as good as co-wrote, I was focused on the tech side of it, she made sense of the characters.

A/N my story and it is Cortexophen okay.


Peter woke hearing a sound, he would have thought that by now he had gotten use to Walters' mid-nightly wander to the fridge. He first registered the scent, it was different, he then knew he was not home. He lay quietly listening to the movements, remembering that he was in Olivia's apartment and that he must have fallen asleep. He heard the footsteps approach the lounge then felt a cover being placed over him, and felt her hand rest on his cheek before she turned away.

Olivia walked to the kitchen, busied herself with making coffee. Her head still mildly aching, she pinched the bridge of her nose, in an attempt to control the flood of memories from her last trans-dimensional jump.

A drug to assist the activation of the recruits, was that what killed those men? If Mr La Grange just been a slip up and the dose had been meant for someone else, who was it?

How were they playing with the drug?

A drug that would allow for the recognition of others- had that been why she had been willing to walk away from Mr La Grange, instead of charging him with rape? His bragging had been as good as a confession.

Olivia took her coffee to the table, and sat down as she turned on her laptop.

Logging into her profile she checked the case over again.

Peter watched her, from the couch, seemingly unknown to her. About ten minutes later Olivia turned to look towards him.

"Peter you can get up if you like."

"You knew I was awake?"

"Yes, I heard the difference in your breathing."

"You can hear me breathe?" He squinted.

"Yes, just like I can hear the neighbours bathroom tap is dripping, and her husband snoring.

"How exactly?"

"Lets just call it one of the side effects of trans dimensional travel."

He swung his legs over the end of the couch, sitting up and rubbing his face, before looking warily at Olivia.

"What time is it?"

"It's just past three."

"And you're working again." He rolled his eyes.

"There is not much else for me to do, I can't sleep when my hearing is like this."

"Ever thought of, maybe say, reading a book."

Olivia looked over at him, a new sharpness in her gaze.

"I'm on a case Peter."

"Yea and you'll burn yourself out if you don't watch it." He said slowly, as with Walter.

"I can't help it, I'm trying to piece together what William said."

"You remembered." It was a statement more than a question.

"Yes, but it does not make any sense yet." She sighed.

"Care to share?"

"Not yet. Not until I find a pattern" Olivia was reluctant to tell him about what William had said about him and Walter, her concern being that this case had something to do with it.

"Well I'd better be getting home to Walter." Peter said, pushing himself up off the couch

"Take the cruiser, you can pick me up."

"Okay, I'll see you later then."

"Yeah." She never even averted her gaze from her work to see Peter's slightly crestfallen face.

The following morning, as she entered the lab, Olivia proceeded to her office. Pulling her note pad closer she continued out to the main lab.

"Okay Walter I need your attention" Olivia spoke to Walter as she placed the papers down on a desk. Peter and Astrid drew closer.

"Right this is what I have so far. All of the Toxicology reports confirmed the following substances in all of the victims."

She handed Walter and Peter each a piece of paper

Peter proceeded to read out loud:

Dopamine;

Piperine;

Protodioscin;

Zimelidine;

Dextrofenfluramine;

Levofenfluramine;

Tadalafil;

then looked at Walter.

Walter turned around, scanning the paper.

"Any thoughts?" Olivia prompted.

"Dopamine is a very powerful neurotransmitter that stimulates the hypothalamus and pituitary glands to release growth hormones. It is also known for enhancing mental alertness, improving coordination, elevating energy levels, and for promoting lean muscle growth."

"Piperine has proven to be a bio-enhancer that increases the body's' ability to extract nutritional substances and improves the body's' defence mechanisms, enabling better utilization of food and supplements"

"Protodioscin converts DHEA (which is the precursor of testosterone) into testosterone, allowing for higher testosterone levels, it also stimulates the liver by helping to convert cholesterol and fats into hormones and energy."

Walter turned around looking at them again

"When these combine the increased testosterone levels would promote protein synthesis, resulting in a positive nitrogen balance. This allows for faster recuperation and recovery from muscular stress, it also has a positive impact on both strength and stamina."

"Belly and I did work on this for the government a while back. Where did I put those notes..." He turned, moving to look for them.

"Walter forget the notes." Peter chirped. "What else?"

"Many years ago before my admission to the mental hospital-"

Peter made to interrupt Walter, but was halted by Olivia raising a hand in his direction.

"The government approached myself and Belly to produce a drug that could enhance a soldiers capabilities in situations of battle." Walter paced, trying to remember. "We found that by combining Dopamine, Piperine and Protodioscin, we could increase the soldier's strength and stamina. The Piperine would to some means limit the amount of food a soldier would require to maintain himself. This could be a derivative of that work." Walter said, waving the paper "But-"

"But what Walter?" She snapped, and Peter glared.

"Belly and I theorised that the combination of these drugs given with LY-94939would create the ultimate performance drug. We were however shocked to find that combining these drugs also increased sex drive, higher sperm counts and semen production."

"I'm not even going to ask how you figured that out Walter." Peter muttered under his breath, and Astrid elbowed him in the ribs gently.

"What is LY-94939?" Astrid asked.

"LY-94939 is more commonly known as Nisoxetine, a very powerful norepinephrine reuptake inhibitor, no longer legal for use in humans." Peter answered. "Walter what were you thinking?" He almost barked.

"Back then it was being researced as an antideperssant, it had all of the effect that would enhance the other drugs used." Walter threw back.

"With one flaw- it is highly addictive." Peter snapped.

"Hey, hey!" Olivia called them back to attention. "Walter, what about the rest of the drugs on the list?"

"Zimelidine, which is a serotonin re-uptake inhibitor they have used in the place of LY-94939, this would act as an anti-depressant. I remember Belly was using it for the development of Cortexophen."

"Okay- whoa there Walter. Your telling me this drug could be linked to Cortexophen? Not only is Zimelidine out-rightly banned for use, you are now connecting these two drugs together." Peter looked at Olivia. "Do you understand what he's saying?" He noted her expression. "You knew because William told you."

"Yes." She nodded her head.

"Cortexophen is a much more complex drug than this, I remember Zimelidine well because it was the one drug that caused flue like symptoms." Walter mumbled, looking at Peter.

"Why was Zimelidine banned?" Astrid asked feeling more a by-stander in the events.

"Zimelidine was been banned due to serious and often fatal, cases of central and or peripheral neuropathy, however in 1980 it had just been discovered and the side effects unknown."

"Walter what of the others?" Olivia prompted again, having noticed Walter's glance at Peter. Did this mean Peter was also subjected to the trails?

"Well Combining Dextrofenfluramine and Levofenfluramine results in Fenfluramine."

Walter continued, Olivia made a note.

"Fenfluramine would control one's appetite, it was used as an appetite suppressant it would make you less inclined to eat. I don't know anything about Tadalafil."

"Oh I can help you with that." Peter chimed, "Tadalafil is a PDE5 inhibitor, commonly known as Cialis or the weekend pill, used for the treatment of erectile dysfunction."

"They have developed a drug to treat that, how interesting. Agent Farnsworth I need information on that." Walter turned to Astrid, who looked shell shocked.

"Too many long words for me Walter. You lost me a while back."

He just smiled gently at her, as Olivia handed over a note of the drugs, which she quickly jotted down.

"Hold up Walter. There is more than one of those on the market." Peter called Walter back from his tangent.

"Would be fascinating to find out how it works." Walter mumbled.

"It's simple really." Peter continued., "By inhibiting the phosphodiesterase type 5 or PDE5, the arteries allow for blood flow into the penis faster, and restricting the blood flow out of the penis by constricting the veins, it also has the effect of lowering the blood pressure."

"How?" Walter asked with renewed interest

"It is believed that by inhibiting PDE5s' affects pulmonary artery vasodilation, thus lowering pulmonary arterial pressure and pulmonary vascular resistance."

"Any side effects?" The woman stepped back, childishly reluctant to take part in the current topic.

"The biggest caution is that people who have taken the drug cannot within 48 hours use organic nitrate medications."

"That's it!" Walter exclaimed suddenly.

"What?" The rest chorused.

The cause of Detective Anderson's death, it had puzzled me why he would die of a heart failure when he was on angina medication."

Olivia reached for the file, looking at the medical records. "It says here that he was on a Glyceryl Trinitrate spray."

"The combination of that spray and the other drugs would have resulted in hyporythmia, that in turn lead to heart failure." Walter grinned proudly at his revelation.

"This could explain him falling to the ground, the convulsions and gripping his chest."Astrid added.

"Yes however the administration of Atropean would have corrected the matter." Walter added thoughtfully.

"Walter are you saying that by administating Atropean you could rightfully prevent a death due to the drug?"

"Oh no this drug will not kill you, it is its combined effects with other drugs that will result in your death."

"Provided you don't react to the Zimelidine." Peter added, crossing his arms across his chest.

"The dosage of Zimelidine is so low that it could not severely effect an adult, in fact it is so low that I'm beginning to question its inclusion"

Olivia studied the list of drugs again

Dopamine

Piperine

Protodioscin

Zimelidine

(Dextrofenfluramine +

Levofenfluramine) Combined = Fenfluramine

Tadalafil

Then it struck her.

"Peter look." She called him over. "If you replace the Dextrofenfluramine and Levofenfluramine with Fenfluramine, the first letters of the last three drugs read Z.F.T."

She looked at him, "That can't be a coincidence. This has to be the drug William told me about"

"Olivia what you have here is a drug that is the equivalent of Viagra on steroids- the ultimate sex drug, as our survivor in the hospital has verified it being."

"It does not make sense." She sighed, exasperated, dragging her fingers through her loose hair.

"What doesn't?"

"William Bell said they were working on a drug that was needed to activate the recruits."

"What, ZFT?"

"Well it just seems that way, but how would it work? He mentioned that they were playing with it loosing sight of its purpose, could this be the drug they plan to market?"

Peter thought for a while. "Hey, Walter..."

"Yes son." Walter pottered over, a beaker of milkshake in one hand, and the list of drugs in the other.

"Would you say this drug could be used to activate the Cortexophen subjects?"

Walter pondered the thought. "It has the bases, but not the effects."

"Walter if you had to change it, so that it would work, what would you do?"

Walter thought for a while "I would increase the amount of Zimelidine and replace the Tadalafil with Guanfacine. The soldier would need to focus"

"Walter one more thing..." Olivia spoke up, holding up a piece of paper from her jacket pocket. "William asked me to show you, What does this mean?"

Walter paled.

"What is it?" Astrid asked, noting the writing and Walter's ashen complexion.

"What Agent Dunham holds there, is the list of drugs needed to create Cortexophen."

Peter took the paper.

It read- Cor-ten-zi-din-2dipphen-cent.
