No, the first one is just typical of the inaccuracy in *popular*-scientific 
statements combined with them being arranged as sound bites, for effect.

The concept of a “relativistic mass” that grows with relative speed that had 
been introduced by others, had been deprecated by Einstein, and has been 
abandoned in teaching long ago (why some scientists would continue to 
disseminate this more confusing, outdated concept is hard for me to 
understand).  Instead, mass is independent of the 3-momentum, therefore of 
the frame of reference and of relative velocity:

<https://en.wikipedia.org/wiki/Mass_in_special_relativity#Relativistic_mass>

So you do not “get heavier”, but you gain momentum relative to a frame of 
reference:

  p = γ m v = m v∕√(1 − v²∕c²)

where m is your mass, p is your (relative) momentum, and v is your 
(relative) speed.  Another way to look at it is your total energy

  E = γ m c² = m c²∕√(1 − v²∕c²).

Your total energy relative to something else increases as you are getting 
faster *relative to that something*, i.e. as v increases (assuming v > 0).

There are two interpretations of this, depending on the set of theories you 
employ:

In classical mechanics, if your total energy increases, your ability 
increases to impart momentum and to do work on a system; so the forces 
between you and other things increase (F = ∂p∕∂t).

In general relativity (GR), your increased total energy is a component of 
the energy–momentum tensor which corresponds to the curvature of spacetime 
around you (G^µν ≡ R_µν − ½ R g_µν = 8πG∕c⁴ T_µν, T⁰⁰ = ρ = ∂(E∕c²)∕∂V).
An increased curvature of spacetime around you makes you travel less 3-space 
in the same time – it looks like it is harder for you to move; also, objects 
around you are increasingly forced to move towards you, following ever more-
curved geodesics of spacetime, making it appear as if a force of gravitation 
between you and them is growing stronger.

As for the second statement, it has been experimentally confirmed
a thousandfold, if not more.  And there are practical applications.

> For whatever reason. They simply can't prove the above.

When will you *ever* learn?  Natural sciences like physics are not about 
proof, but about confirming or refuting theories that are models of the 
world, by experiments.  Which *has been done*, and the two theories of 
relativity have been confirmed in every single experiment so far.

> Required instruments are not available.

Utter nonsense, as you well know.  Just *this year* one of the instruments 
required (LIGO) spectacularly confirmed GR’s prediction of gravitational 
waves.  *One year ago*, an instrument (Planck spacecraft) enabled scientists 
to determine the age of the universe using GR.  *Two years ago*, another 
instrument (the LHC) that works based on special relativity (see “total 
energy” above) enabled scientists to find the elusive Higgs boson, 
confirming our models of the constituents of matter (QED and QCD) which
also would give wrong predictions without special relativity.  And so on.
