Peptides and steroids are completely different things with completely different actions in the body. Side effects as with everything are dose and cycle length, dependant. If what you're asking is to use peptides instead of steroids the answer is no my friend.
HGH, IGF-1 and so on, are to be used in combination with steroids, especially the very androgeninc ones like test and tren and not only. Insulin and thyrormones come in play to create a very good but alas, expensive synergy.
