On Travel;
I go to Thailand yearly with the wife to see family. I take my Dr prescribed Test cyp. I didn't take syringes the 1st trip - bad mistake. Pharmacies may sell you steroids over the counter but not syringes. Authorityies think prohibiting syringes will stop drug abuse... lol.
Anyway, never an issue.
Are you going to refill the vial for the trip back?
On sleep;
Have you researched Alpha GPC and Magnesiun L-threonate?

From Amazon reviewer RMW:
This is a side-by-side comparison of ten leading magnesium l-threonate supplements: Doctor's Best Brain Magnesium (75 mgs), Jarrow MagMind Magnesium L-Threonate, Life Extension Neuro-Mag Magnesium L-Threonate, Swanson Magnesium L-Threonate, Source Naturals Magtein, Vitacost Magtein Magnesium L-Threonate, Pure Encapsulations CogniMag, Dr. Mercola Magnesium L-Threonate, and Piping Rock Magtein Magnesium L-Threonate.
FORMS OF MAGNESIUM SUPPLEMENTS: Magnesium supplements come in a variety of forms, such as magnesium glycinate, a chelated form of magnesium that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for those who are trying to correct a deficiency; magnesium citrate, which is a magnesium with citric acid, and has laxative properties; magnesium oxide, which is a non-chelated type of magnesium, that has stool softening properties; and Magnesium L-Threonate, which is a newer, emerging form of magnesium supplement that appears to have promising cognitive benefits. The purpose of this review is to concentrate on Magnesium L-Threonate, better known as "MgT."
MAGNESIUM L-THREONATE OVERVIEW: In addition to support for cardiovascular and bone health, energy, metabolism, and mood, provided by elemental magnesium, researchers are now focusing on magnesium's benefits for cognitive function. Magnesium has long been known as a key nutrient for optimal brain function. More recently, scientists have found it specifically promotes learning and memory as a result of its beneficial effect on synaptic plasticity and density.
The neurodegenerative processes involved in memory loss result from deterioration of connectivity between brain cells but are not a natural function of aging. Memory loss is now known to be associated with a loss of synaptic density and plasticity in the brain. Low magnesium levels may contribute to such losses.
Unfortunately, it is very hard for your body to maintain optimal levels of magnesium in the brain. This problem is of special concern for maturing individuals, as magnesium deficiency increases over time. Most magnesium supplements are not readily absorbed into the nervous system. Until recently, no widely available forms of magnesium met the criteria needed for rapid absorption and efficient transfer into the central nervous system.
However, an innovative team of researchers from the Massachusetts Institute of Technology ("MIT") recently found a way to surmount this obstacle. They formulated a new magnesium compound called Magnesium-L-Threonate (MgT).
MgT boosts brain magnesium levels better than standard supplements. Studies reveal that MgT produces dramatic increases in synaptic density and plasticity, resulting in similar improvements in memory function itself.
MgT is now thought to be effective in several areas:
Improvement in Spatial Short-Term Memory. Spatial working memory is an essential memory function, helping you remember where things are and where you are in relation to the world over the short term. It is working memory that enables you to find your car keys as you head out the door or return to the correct page in the magazine you were reading a few minutes ago.
Enhanced Spatial Long-Term Memory. Long-term spatial memory is crucial for older individuals. It's how you remember where you live or how to get to the grocery store. Loss of spatial long-term memory is one of the main reasons that older people with dementia get lost running even simple errands.
Better Recall. One critical memory function is the ability to bring up an important memory based on only partial information, a function called pattern completion. You use pattern completion memory to find your way around a familiar neighborhood after dark or following a heavy snowstorm. In both cases, some familiar cues are gone, but a healthy brain will fill in the missing details by completing a recognizable pattern.
The MIT team is rapidly putting in place two human studies of MgT on memory function, with results expected in the near future. Meanwhile, they have recently discovered several new roles for MgT in managing memory, in this case unwanted memories of the kind associated with post-traumatic stress disorder ("PTSD"). As a Vietnam vet, and one who is very familiar with the effects of PTSD, I am following this development closely.
The suggested daily dose of MgT is 2,000 mgs per serving (a "serving" is usually two or three pills). While this supplies only 144 mg of elemental magnesium per serving, its superior absorption into the bloodstream and nervous system make it a preferred choice for aging humans to supplement with.

PRICE PER PILL: Pure Encapsulations CogniMag ($.50 per capsule) is the most expensive per pill of those in the comparison; followed by Vitacost Magtein(tm) Magnesium L-Threonate ($.46 per capsule); followed by Doctor's Best Brain Magnesium (75 mgs) ($.42 per capsule); followed by Dr. Mercola Magnesium L-Threonate ($.36 per capsule); followed by Swanson Magnesium L-Threonate ($.31 per capsule); followed by Piping Rock Magtein Magnesium L-Threonate ($.28 per capsule); followed by Jarrow MagMind Magnesium L-Threonate ($.25 per capsule), and Life Extension Neuro-Mag Magnesium L-Threonate ($.25 per capsule); followed by Source Naturals Magtein(tm) (180 Count)($.22 per capsule); and followed by Source Naturals Magtein(tm) (90 Count)($.20 per capsule), which is the least expensive per pill of those in the comparison.
However, Doctor's Best Brain Magnesium (60 Count) contains considerably more MgT per pill than the others, so in order to determine the least expensive product, we need to turn to the "price per 100 MgT of MgT." When we do, it appears that Source Naturals Magtein(tm) (90 Count), overall, is the least expensive of those in the comparison. See, below.
PRICE PER 100 MGS OF MGT: Pure Encapsulations CogniMag ($.10 per 100 mgs MgT) is the most expensive per 100 mgs of MgT of those in the comparison; followed by Vitacost Magtein(tm) Magnesium L-Threonate ($.07 per 100 mgs MgT) and Dr. Mercola Magnesium L-Threonate ($.07 per 100 mgs MgT); followed by Swanson Magnesium L-Threonate ($.05 per 100 mgs MgT); followed by Doctor's Best Brain Magnesium (75 mgs) ($.04 per 100 mgs MgT), Jarrow MagMind Magnesium L-Threonate ($.04 per 100 mgs MgT), Life Extension Neuro-Mag Magnesium L-Threonate ($.04 per 100 mgs MgT), and Piping Rock Magtein Magnesium L-Threonate ($.04 per 100 mgs MgT); and followed by Source Naturals Magtein(tm) (90 Count) (.03 per 100 mgs MgT) and Source Naturals Magtein(tm) (180 Count) ($.03 per 100 mgs MgT), which is the least expensive per 100 mgs of MgT of those in the comparison.
SOY/GMO/CHOLESTEROL CONTENT: None of these products contain soy, GMOs, or cholesterol.
STEARATES: All of these products contain magnesium stearate with the exception of Doctor's Best Brain Magnesium (75 mgs) and Pure Encapsulations CogniMag.
ASCORBYL PALMITATE: Only Doctor's Best Brain Magnesium (75 mgs) and Pure Encapsulations CogniMag contain ascorbyl palmitate.
KOSHER: None of these products is certified Kosher or Halal.
VEGETARIAN: All of these products are vegetarian, except Source Naturals Magtein, Dr. Mercola Magnesium L-Threonate, and Piping Rock Magtein Magnesium L-Threonate.
CHELATED: All of these products are chelated, except Life Extension Neuro-Mag Magnesium L-Threonate and Vitacost Magtein Magnesium L-Threonate. A chelated form of magnesium l-threonate tends to provide the highest levels of absorption and bioavailability.
MEALS: Magnesium supplements are best taken with a meal containing some fat, as they are more efficiently absorbed when taken with food.
OPINION: In my opinion, all of these magnesium supplements are excellent. It's a matter of personal preference. Price should be an important consideration. I believe additional human research is needed for MgT before the impressive product claims are substantiated.
RATING:
I have rated all of these products five stars, but, in my opinion, there is still important research to be done on MgT, particularly involving human studies. It is my understanding that the research has been completed and the results are favorable, but the information has not yet been published.
I have separately reviewed all of these products.
