It's nearly impossible to get a full set of composite on w/o getting buffed. So the easiest thing to do is to get some food like Breathe of Heaven or Fishkill (not the right name but close). Focus Sundaes are good too. The other alternative is spice but the downside is when you are coming down from the spice, you will sometimes go incap depening on the stat buffed.
finally, the best solution but the hardest to get is buffed from a doctor since you get the biggest buff and it lasts the longest. Just remember, if you get food, try to get a crate if you can afford it. Main reason is if you want to heal, you heal faster w/o your armor on and if you take it off, you need to buffs to get it back on.
Some other solutions:
1. Remember that stat migration takes time, about 8 hours of in-game time depending on how drasticly you change your stats. But even with full comp, its unlikely you can mod your stats enough to be able to put on/remove your armor w/o help.
2. Get it sliced. This is hit or miss and a bit of a risk unless you know the Smuggler. Smugglers can reduce the required HAM to wear the armor BUT they don't choose the effect. The other effect is that they could end up increasing the effectiveness of the armor.
Hope that helps.
