Is it safe to combine multiple research peptides?

There is essentially no published human data on combining unapproved research peptides with each other, because the trials that exist study one compound against a placebo, not stacked combinations. Community protocols combining several peptides at once are common online but are self reported, not controlled data. The individual evidence gaps for each compound do not shrink when peptides are combined; if anything, the unknowns multiply.
