Muscle growth noticeably accelerated

Verified

Added IGF-1 LR3 to my protocol and within 3 weeks noticed faster recovery and new growth in stubborn muscle groups. Traps and delts responded particularly well. Gained 6 lbs of lean mass in 6 weeks while staying at the same body fat percentage. Impressive.

Recovery between sessions dramatically improved

Verified

Training 6 days a week was leaving me overtrained. IGF-1 LR3 allowed me to handle the volume without the accumulated fatigue. Muscle soreness resolves in half the time. Strength is going up consistently on all lifts.

Lean gains without water retention

Verified

What I appreciate about IGF-1 LR3 is the quality of the gains. No bloating, no water weight, just steady lean tissue accrual. Put on about 4 lbs of muscle over 5 weeks while slightly reducing body fat. The look is tight and dry.

Hyperplasia potential is real

Verified

The extended half-life of the LR3 variant makes dosing practical. After 4 weeks I noticed muscle fullness that feels different from hypertrophy alone. Pumps are incredible and lasting. Strength in the 8-12 rep range went up noticeably.
