By no means could it be said that it will "definitely" help, our physiologies are all so nuanced that everyone has varying degrees of efficacy, however I would say that using them in tandem is likely the best-case result you will get compared to either peptide alone.
Additionally, playing with timing of dosage also very much seems to have impact- especially with the Epithalon, so if you're going to give it/them a go, definitely explore PM doses VS AM doses, many find greater effect from one over the other.
