LSA isn't weak, but ur MG seeds/extract is. LSA sources are very incosistant/unpredictable in terms of content. In my experience most LSA sources seem to be WAAYYY weaker than most other people's sources, it's either bad luck or some odd conspiracy

lol... ur best bet, HBWR, ask the vendor too. It's very rare to come across the 10-15 seed batches but usually 30-100 HBWR seeds are needed, but it's WAAYYY worth it IMO.
LSA doesn't suck, IMO it's better than LSD, just hard to get a good/reliable source. The trip is reminisant of DMT/ayahuasca. It's like candy flipping with no negatives and feels completely natural. music is better than acid, visuals are just as good, and unlike acid u get a great bodyhi instead of a bodyload, no paranoia or cracked out hangover feeling that u just want to end like LSD
