I don't think anyone could give you a concrete answer on that. Most peptides have little to no human data on them. Even BPC 157 and TB 500 are questionable. I would say in your situation stay with the proven. Eat, sleep, train, ensure your diet is aligned with your goals of losing our gaining weight and be consistent, then be consistent some more, then be consistent even more. Creatine as the primary supp. Leave the peptides for when you have money to burn. JMO
