I know Ligandrol is not a peptides but since this forum has no SARM's category, I will leave the information here.
Can you use LGD 4033 in solo cycle?
first, since I'm new here i will introduce a little, I am a trainer for 15 years and love experiments in special to test sarms peptides and other products like steroids.
About the question, NO, do not use LGD 4033 solo.
Why? Ligandrol decreases your personal testosterone, so you have started using it ... and in time it will have a side effect like low test.
What to do? Stack Ligandrol (LGD 4033) with antiestrogen products, on of them Arimidex or Exemestane.
Hope I brought clarity..
