Best pep for muscle/leaning
for context. Reta for 5 months, very low dose (.25ml,2x week), One cycle of KLOW for 8 weeks (current off cycle). Goal weight attained with Reta. Overall feeling healthy and energetic. Starting gym training sessions targeting muscle buildup (goal is not to get super jacked, but toned/leaned). Wondering what is the best option for this. Tesa, Ipa, sermorelin, CJC, combos of these...? Not sure about continuing KLOW at this point.
Thanks in advance
